- stretchable hydrogel electronics and devices, stretchable hydrogel sheet, stretchable and transparent hydrogel, highly stretchable hydrogel ..!!! Most hydrogels have relatively low tensile strength and low elasticity, which limits their application capacity in the biomedical field. In order to improve the mechanical properties of hydrogels, highly stretchable and tough hydrogels have been invented recently. If a sensor is to be wearable, it should generally be highly stretchable to ensure comfort for the wearer. The biocompatible hydrogel has the ability to strecht up to a strain of 5000%. Highly stretchable and tough hydrogels can be implemented in multiple diferent fields, such as mechanical sensors. Properties important to making a good mechanical sensor, such as gauge factor, self-healing, and having strong mechanical properties, can be seen within these hydrogels. Highly stretchable and tough hydrogels, with great adhesion strength and healing times, can be utilized for wound healing. The mechanical properties of tough, highly stretchable hydrogels can be used for drug delivery.

Hi... This was a really good and informative video... I wanted to ask if we could use this hydrogel to make skin patches ?
Of course you can use it. There are many articles in the literature related to this.
Have you explored the rheological properties of this hydrogel yet? Does it exhibit shear thinning properties with shear stress?
Their rheological properties can be adjustable using Ca ions.
How to store this? And what is the shelf life of this hydrogel
Informative video,, I am also working on Chitosan based temperature and pH sensitive hydrogel,, i am using CS, NIPAAM, Amps, gultaraldehyde as a crosslinker, and APS as initiator, but my gel is becoming hard he brittle, it hasn't show any elasticity, can You please make a video on Chitosan based hydrogel ASAP,, thank you
Thank you. I hope. You can use glycerin.
Wow this was nice and informative vdo! Can u plz tell me which polymer should we use for preparing gel like hydrogel ..which one gelatin or collagen or chitosan so that it should have some solud like consistency
Thank u, u can prepare their copolymer composite
Hi, thanks for the video. I thought you would add also calcium chloride or calcium sulfate in order to crosslink the alginate as well and make a double network. Am I wrong? how does the presence or absence of an alginate crosslinker affect the properties of the gel? Thanks a lot in advance for your answer.
Yes u can use Ca ions for physically crosslinking the alginate segment. Not only calcium but also other polyvalent cations can be used for physical crosslinking. In this video, bentonite clay containing polyvalent cations is used in its structure. This clay made the hydrogel harder.
the physical crosslink as a sacrifice neetwork which can dissipate energy to improve the gel's toughness.
can you please let me know why you have used those particular chemicals? what was the need and what properties do they impart in hydrogel? it will be of great help.
Sodium alginate improve the mechanic properties.
I just have a question about making leather from the cactus plant and what are the raw materials to make leather, and I know one of the materials used is polymer, and I hope someone can help about making vegan leathers.
How can I contact you
Hi...Tnx for sharing your experience. How can we increase the adhesion of hydrogels?
U can increased using natural or sentetic polymer or additive. There is a many studies in the literature.
Cihangir Bey iyi çalışmalar. Yara bakım ürünlerinde kullanılan hidrojellerle aynı mı sentezlediğiniz jel.?
Benzer, ama iyi saflaştırma yapmanız gerekir.
May I know how do you remove the remnant acrylamide monomer in the hydrogel? it is a neurotoxin, could it be put on the skin directly?
YeS, U are right.
Hello, would it be possible to get a list of the things you've used in creating the hydrogel? It would be very helpful for our research experimentation, thank you!
There is a detailed explanation in the video. If you want to search 'acrylamide-based stretchable hydrogels', there are many studies in the literature.
Hi there,
Have you ever worked with chitosan to make hydrogels? In combination or alone
yes u can use chitosan. But it is not combine with alginate because their electronic properties. Chitosan is the cationic while alginate anionic.
Hi! Do you know how to make home made hydrocolloid patches/bandages? Would love to learn if you could give me some tips!🙂
U can use PVA, starch, callogen, alginate, CMC. An u can use borax, glutaraldehyde or CaCl2 as physically crosslinker.
@@polymerscope6881 what about chitosan
?
can you sugest any resurch paper ?
U can find many article in the literature.
hi, can i know the material of the plate that used in the video ? Is plastic or styrofoam? Thank you
Popular known styrofoam plate.
Hi, i hope you notice my comment. I am willing to do somtihng similer to your work, but I will be useing natural-polymer instade of poly(Acrylamide). Could you help me to find sutable polymer or how to find.
Thank you.
U can use alginate, chitosan, gelatin etc. U can crosslink by gluderaldehyde. Or u can use PVA. Its synthetic but biocompitable. U can crosslink it by gluderaldehyte or Freeze Thaw method.
Hi. Can you tell me how long do you need to wait before adding each material in this solution?
Just wait until you have a homogeneous mixture.
Link for its paper?
What about the homopolymers formed or any interacted monomers?
This PVA polymer composite, pure PVA, not contain other monmomer or polymer.
I was very impressed by your video.
Why did you put in bentonite??
Thank you, bentonite is the good filler, I used it to increase the toughness of the material.

hello super late but I wanna ask if this self heals? like if we cut it up into pieces would we still be able to merge them all together into 1 piece?
This is not but u can develope self healing worms using PVA
Sir how you prepared the NA ALGINATE SOLUTION
2 g / 100 ml water
Hi! I'm unable to differentiate between hybrid hydrogels and synthetic hydrogels? I know that hybrid are a combination of natural and synthetic hydrogels, but how do I know which one is which by reading its name.
Yes u can.
Do you think that a hydrogel would work for a gel insole product for shoes? Could it work for the entire shoe?
Of course you can develop it for this purpose.
Is there any article relevant to this procedure??
In press process.
In vdo hydrogel is of film what can be added to make hard so that we can cut
U can add the multi cations contain clay such as Bentonite, it will do stronger
May I ask some questions,…Why u put bentonite to systhesis hydrogel & reason .
Betonite contains cations such multi charge cations like Ca cations, these cations crosslink the alginate chains which them makes stronger.
Is it possible to start with polyacrylamide instead of its precursor?
NO. The crosslinker is incorporated into the polymer chains through radical addition to carbon-carbon double bonds. You need active radical sites. And you can't add initiator again to start the reaction of crosslinker with polyacrylamide because there're too few carbon-carbon double bonds in polyacrylamide.
Yes u can
Dear sir, how long did the cooling process take and what was the degree?
24 hours room temperature.
Can I pour an antioxidant solution to make an antioxidant hydrogel?
Yes, for example, if u add essential oil, u can use in wound healing application such as burn therapy.
How to maintain the stability of hydrogel
keeping it moist and clean.
Hi sir... I have a question?? Sir how to preserve this hydrogel for future experiment??
You can wrap it in aluminum foil and store it in the refrigerator.
How many grams of alginate and water were added in step 1?
2 g/ 100 ml
Can I start without Na Alginate?
i.e Dissolve acrylamide in water?
Than add MBA than APS than TMEDA
If u want to make a strach, u should us Na- Alginate.
sir please how much Bentonite have you added
It is not necessary to use bentonite. if you use it it gets tough.
Hello sir, can i use collagen instead of Na-Alginate?
It can be but not flexible enough.
Can you please tell me which hydrogel should I prepare for the removal of drugs from wastewater?
You can prepare anionic hydrogels for cationic substances. So with AAm you can use AMPS, VSA, AAc. You can use chitosan polymer composite with AAm for adsorption of anionic substance.
I am working on hydrogels . Using PVA POLYMER , natural starch extracted from mango karnel , glutaraldehyde as crosslinking agent
Good job.
Can we use something elsa instead of NA algnite
What type of tests and characterisations you done after the synthesis
Dear where are u from? I'm also working on hydrogel for wearable and stretchable devices in Korea

The stirring part should be replaced by adding other components so that it can be injected into hip with artritis.
Is it possible for making strechable hydrogel using chitosan
Yes.
I tried , using glutaraldehyde,(crosslinker)glycerol(plasticizer) but didn't work out, why? Strechabillity is weak,
@@aswathyc9799 I suggest you review the sample articles on chitosan glutaraldehyde.
@@aswathyc9799 hello ,, your hydrogel from Chitosan has been prepared???
Hii, I wish to know about two things
1. Adding 15 grams of acrylamide wouldn't be toxic?? I mean will the bandage still remain biocompatible?
2. How can we reduce the stickyness of hydrogel?
If your polymer fully pure, it is not toxic, or u can use other crosslinking method such as frezee thaw, gluteraldehyte., İf u use cacl2 or Bentonite clay, it will be stronger due to crosslinking alginate segments.
@@polymerscope6881 Hello, please could you explain again. If I used the exact same materials used in your video, will it be cytotoxic?
Sir can I use cellulose in this procedure??
Yes, u can use the carboxy methyl celluslose or their derivatives.
Thank u sir.kindly suggest me what should be the quantity of cellulose?n again with this can I add encapsulated essential oils also to prepare dermal patch.
HI thıs used tens pad
Yes but expensive for this purpose.
What you did for drying ?
You can use glycerin and silica gel to prevent drying.
@@polymerscope6881 how much concentration of glycerine use
Hi! Would it be possible to know the specific rpm you used in stirring? Is it constant throughout the experiment? I would also like to know the duration of stirring if you don't mind. Thank you very much!
A mixing speed that satisfies you will suffice. The important thing is to ensure a homogeneous mixture.
How you dried this hydrogel?
U can use oven.
@@polymerscope6881 thanks for reply. Can you tell how much time and temperature
@@alchemacademy5799 did u kept on oven!
Is this edible?
No.
Sir i followed the same methodology with same chemicals concentration . And after 24 hr of drying My gel is hard
U dont use bentonite.
Yes i used Bentonite
Sir can you please send me your email so that i could ahare the pics of my gel
How u removed Air bubbles
Vacuum.
@@polymerscope6881 thanks for reply I also used vacuum while I was doing my project work to remove air bubbles
@@nileshmarkad1518 then do not start the polymerization reaction immediately after the homogeneous mixture is achieved, wait for the air bubbles to rise to the solution surface, you can try the ultrasonic bath to speed up this process.
I dont care wot its made of,i dont want that in my body. Silicone was safe……until it hardened…..and wasnt safe!
