Thanks mam for the simplest explanation of the differences between the blends and composites. Mam can the biopolymer-plastic mixture be categorised as blends or composite???
Yes. Biopolymer-plastic mixture is also categorized as blend and composite e.g., natural fiber reinforced synthetic polymer composite and natural-synthetic polymer blends.
can you explain about the importance to evaluate the glass transition temperature (Tg) and melting point (Tm) for polymer blends and polymer composites?
Madam pls discuss elaborately about polymer blend. Types and How can select the material for miscible/immiscble blends. Thermodynamics of blend. Solubility of polymers. Cover gate sylabus pls...
Here is video link for TGA and DMA th-cam.com/video/fUFuoLemv9A/w-d-xo.html th-cam.com/video/g9QYcFXGJgg/w-d-xo.html th-cam.com/video/wsPwICTgO5w/w-d-xo.html
It's still not clear to me that what's exact differences between miscible blend and compitable blend? As I studied, miscible is uniforme and hemogen single phase with one Tg, while compatible blend is uniforme and single phase but with tow Tg. Is that right? In the compitible belnd we cannot see phase seperation in the SEM and mechanical properties also son't change. Plesae correct me if i took it worng.
We have to be very clear about the term - miscible blends are made of polymers which are compatible at molecular scale were are immiscible blend can be made compatible by addition of a compatibilizer. And the blend containing a compatibilizer is called compatibilized blend. A compatibilized blend gives better mechanical properties then non-compatibilized immiscible blend. Compatibilized blends are also called polymer alloy.
PE and PP form immiscible blends due to entropy. Entropy measures randomness of polymer chains. To mix well with each other entropy of the mix should be higher than the individual polymers. But due to branch structure of PP and linear structure of PE these polymers do not come close to each other rather like to stay with similar polymer chains therefore do not mix well.
Polymer blend is mixture of two or more than two polymers. If the two polymers form miscible blend they form single phase. If blend is immiscible then two phases form.

Great class ma'am kindly send the notes like this for gate
Many thanks for this helpful explanation!
Glad it was helpful!
Plzz make video on blends & composites of polyimide as electrolyte membrane...or any reference.

Dear If you've got the answer please share here...

Thanks for your comment. We will try to make video covering all the topics.
Good video.. we need more videos like this
More to come! Thank you.
Please explain log and inverse additivity rule
This video is very informative thank you so much 🙏🙏
Please make video on polymer blend in detail.
Sure 👍. Thanks for your comment.
Can we make a whatsapp group about polymer?
Hello maam, can you make a video on pi-pi stacking? How does it form and what polymers show it? And it's analysis using XRD?
Its a limited interest topic...but we will try.
Great explanation
Thank you so much!!
You are welcome!
Please make videos on thermal property of polymer.. TGA, DMA
Here is video link for TGA and DMA

@@PolymerWorld will you please provide us rheology . It will be helpful for us..♥️
Really informative videos you have made. Thanks 🙏
@@mongaldutta8615 We will definitely make video on polymer rheology.

Why PE and PP blend is not compatible?? Please answer
PE and PP form immiscible blends due to entropy. Entropy measures randomness of polymer chains. To mix well with each other entropy of the mix should be higher than the individual polymers. But due to branch structure of PP and linear structure of PE these polymers do not come close to each other rather like to stay with similar polymer chains therefore do not mix well.
Might be the difference of Tg ?
Nice explained
Thanks for liking.
thanks mam
Keep watching!
Excellent👌
Thanks a lot 😊
So polymer blend single or phase
* or two phase
Polymer blend is mixture of two or more than two polymers. If the two polymers form miscible blend they form single phase. If blend is immiscible then two phases form.
@@PolymerWorld thanks for your answer
💯
Good
Thank you.
