BIOPLASTIC FROM POTATO STARCH

- Hello
in this video, I make bioplastic out of potato starch.
-Extraction of the starch from potatoes: • Extracting the starch ...
Here the starch act as a polymer and by adding the reagents he suffers some transformation on his bondings making the chains more linear and plastic.
Are there any other effective alternative products for glycerin?
How does the humidity effect the solidifying process?
Hola! :)
De casualidad tienes algún artículo donde pueda ver mas del procedimiento?
Alright, I made your recipe, but how many time I have to let stand the recipe ?
Thank you for your help 😊
What is adios mucha cha film made out of?
can I ask you something?? Wich ingredients do you need??
How many days it dry out?
60° how much time?
What are the names of the chemicals used? I can’t read Portuguese so I’m sorry
I tried to make beer before with starch before I knew how to convert it to surgar properly.And it came out to be like the polymer. Hard and thick. I just did it again just a few days ago and it wasn’t the case this time. Now I’ll expecting to have potato beers soon
Starch, a large-molecule carbohydrate used in making beer. To make any alcoholic beverage, there must be sugar present for yeast to ferment.
that's nice
hello,
As of my knowledge this starch based plastic are hygroscopic ( adsorb water ) is it the case with your samples?
hello, yes it is, but we did not test, to have the exact rate of how much water it absorbed , we tried to see if it was soluble in water but it did not dissolve so easily with hot water and mixing, we did not make a anti-aderent coat but thats possible
Hi, just wanna ask if it is okay to use a vegetable glycerin ?
Hi, if it is the same molecular formula then I don't see any problem. The only difference maybe the resource that is beeing used.
Can i let it dry in room temperature or do we need to put in in a oven?
you can do both, but if you put on the oven you need to control the temperature and the time
Hi can i ask something? What kind of glycerin did you use, for the soap one or for the food one?
Hello, i used the glycerin from the lab the one you buy as a quemical product, but you can substitute for the glycerin we buy at the pharmacy so i guess the one you use for the soap.
@@izaza4816 thanks for the reply!by the way this is my research study😘
@@amberjadepacia781 good luck
I need a research topic and I decided on plastic. Do you have any articles that I can read to help me?
Hello, i think is nice to understand the basics firts, like what are plastics why are they called like that, what are polymers, how are they made, its primarily charactheriscs thermoplastics, thermosets etc, its structures, processes of polymerization, and then processes into making other materials

Iza Rossi You’re so nice! Thank you very much! I subscribed❤️ I wish you all the best.
60 degree Celsius for how long?
Hola!!
Podrías explicarme bien a qué temperatura realizaste el proceso y cuáles fueron las cantidades?
Hola!
Las cantidades de reactivos utilizados fueron:
-20 gramos de fécula de patata, en casa.
-20 mililitros de vinagre
-50 mililitros de agua
- 5 gramos de glicerina
Mezclar todo y ponerlo a calentar, el calentamiento sirve como disparador de la polimerización y cataliza el proceso.
La temperatura para la polimerización fue de 70 grados durante 30 a 25 minutos, mezclando casi todo el proceso, luego se puede verter en placas de Petri.
en verdad essas son las cantidades, mas exatas:
20 gramos de almidón en polvo seco en invernadero.
con 175 ml de agua, 75 ml de vinagre y 10 ml de glicerina, colocados en un vaso de precipitados y
calentar durante 45 minutos hasta obtener una mezcla homogénea y viscosa, esparcir en platos
de petri para secar durante 2 semanas.
vaso precipitados és el bequer
@@izaza4816 hello!! can you please translate the materials to english?
Great video! Any way you can make a PLA / starch bio composite plastic? It is for a school project
you might try to make a composit material with an iron and some baking paper. watch out though glasdpoint of pla may be beyond the ignition point of potatoestarch.

Obrigado for your explanation
now how can I fit this in my 3d printer?
Hi, i don't think this plastic can be used in your 3d printer or any other polymeric processing like injection or extruder, is different than comercial "biodegradable" plastics. But you can read this article about bioplastics used on 3d printers, but most of them are degradeble and not biodegradable: www.sculpteo.com/en/3d-learning-hub/3d-printing-materials-guide/3d-printing-bioplastics/
Hope it helps :)
@@izaza4816 thanks, that save me the time and energy to experiment on these
you're welcome

Can we use glycerol instead of glycerin?
hello, yes you can since they are the same thing, only differs in the name or the level of purity.
@@izaza4816 ohh ok.. Thank you for your reply😊 I'm going to do that tomorrow
@@Sneha_294 you are welcome. That's nice, if you can, let me know the results :).
interesante
oloco, tava procurando um vídeo em inglês e achei uma brasileira kkkkkkkkkkk
Is it elastic?
Hello, we never made any tests to really see its elasticity but once you apply a tension it straches and tears. We are still testing it's properties. But this was just a demonstration for a english work. But once it dries i would't concider that elastic but has plastic porperties, is not vitrious.
if you would like i can send you the article we made
Super thank you,🥰
@@izaza4816 can u please send the article
@@yashodhaa7490 Hello, it's published in portuguese on a congress anal on this link you can read it's page 8:
