i mean, is just dried up cooked starch, this "plastic" is not suitable from any application as its not waterproof, is extremely fragile and is almost impossible to dry uniformly without cracking/breaking. the glicerine doesn't do anything, because glycerol needs a catalyst to polimerize, maybe is making the mixture a little bit more flexible because its just oil in the end.
You probably didn´t heat them or not evenly enough. One way to test this is to heat a bit in the microwave. It will warm through and through. This gives you a nice baseline of what kind of sturdiness can be achieved. One minute will do it in any microwave worth it´s name.
Hello I'm a high school student that is currently doing experiments and writing a report based on biodegradable plastic. Can you please tell us the molecular formula and specific steps of decomposing bio plastic?
Just make it. I tell you how to do it even more easily at the end. But first your other questions: You can decompose very easily using water, it is soluable, you can guess the process from there :). For chemical composition, you need to know the composition of the monomers, in this case a polysacharide, so basically a dextrose-ring as a base. (sugar or basically two dextrose rings is C12H22O11, you do the math..) Starch itself is already a polymer, we write the monomer (the dextrose ring) with an extra n to suggest it is many monomers.. This gives you (C6H10O5)n. When heated and cooled the starch just forms longer chains, resulting in the extra strength. The acid from the vinegar is just there to help in this process, called a katalyst (something that helps in a chemical process, without being used up). I don´t exactly know what the glycerin is used for, but I know glycerol can be used to do polymerisation, so probably just for added strength (glycerin =95% glycerol, so just less pure glycerol C3H8O3). You can make a very easy bioplastic (that is truly bio, so without the propane-based or fossil-fuel based glycerol, wich is called a starch based completely biodegradable polymer: SCBP). Just corn-starch and water put in the microwave for a minute will give you a bioplastic. WARNING: put it in a plastic bag, because it WILL spatter once the water starts to cook and your mom will make you clean it. You can actually eat the resulting plastic, without any problems, as long as you don´t eat too much of it, it might clog your intestines if you do that.. So don´t overdo it. I know it was 5 months since you asked the question, but you are probably not the last student to come through here :)
Hello can I ask if did you test the durability of your product and its biodegradability, thank you.
Did it shrink amd crack? Is it water proof?
I think it's not waterproof based on my observations and it also needs improvements. Though it is a great project after all.
@@iamsherk2605 Thank you. Yes, I agree. I have developed a better formula for a video on my channel.
@@GEOsustainable did you ever produce this video? I would like to see your formula.
What type of glycerin did you use the food one or the one for the soap?
Nice work, I'm doing my project on plastic from banana peels

Hello,Why do our own bioplastics become brittle when completely dried？
You probably didn´t heat them or not evenly enough. One way to test this is to heat a bit in the microwave. It will warm through and through. This gives you a nice baseline of what kind of sturdiness can be achieved. One minute will do it in any microwave worth it´s name.
Why did it deform in the end?
probably retracting when drying
I was wondering if I could mix the two to clean copper pipes without ketchup.
would corn starch, vinegar, and water.... change into a color?
what
I don't think so... Bcz these three are already colourless
It would turn colorless
I’m sorry but 10 g of plastic doesn’t dissolve in 50 ml of water
for how many days we want to cool it
up to 2
Super

im doing exactly same thing, have you found any more info?

Hello I try to make this bioplastic but they can't made so plz suggest me and plz sent this molecular formula
hvor er det fedt for dig
