Hey! I know this is a weird question, but I need to make a grow-toy (lie the dinosaurs that grow in water) from scratch. I can't find any informatio on it other that it is made of "a mixture of sodium polyacrylate, polyvinyl acetate (a polymer used as a binder) and ethylene vinyl acetate". However, I have no idea how to make them. Could You please walk me through the process of making it from scratch? Is it even possible without a professional equipment?

[@soro008]

Is there another alternative chemical I can uses to substitute VSA?

[@priyankameena6451]

Is there need to add APS , if we are using PNIPAm?

[@thuantv809]

I have some questions that I hope you can answer: 1/ What is the temperature of the solution after being divided and stirred before being placed in ice water? 2/ VSA put it in for the wrong purpose?

[@yumnaeriqsousi7643]

can you synthesize sodium polyacrylate

how did you fixed temperature at 10 during polymerization reaction?

[@mallikarjunjalageri5020]

Hello sir may i know standard dimensions of hydrogel using for compression and tensile purpose .

[@kunalsinha52]

I am trying to prepare this hydrogel, without VSA. Here there is no mention of Nitrogen environment, which I frequently encounter while going through literature. It would be great if you can throw some light on it.

[@hesamkasraie6820]

Thanks for sharing this video.I have a question,Can I add chitosan with PEI (polyethylenamine)to this mixture?Thank you.

[@polymerscope6881]

Of course you can add. However, since the ionic power balance will change, there will be differences in swelling values.

[@hesamkasraie6820]

Thanks for your reply.Can I have your email address?

[@nadherdaman1885]

thanks the swelling ratio increases with an increase of VSA due to an increased in functional groups of SO3 in VSA are negatively charged polyelectrolytes in the polymerization medium; therefore, strong electrostatic repulsive forces hydrogel would be obtained that has a higher swelling capacity.

I'm trying to make a polyacrylamide gel (that has Triton X for increased hydrophilicity), but the surface keeps swelling/wrinkling. How would I keep it smooth?

[@polymerscope6881]

If the polymerization reaction is slow, it will have a smooth surface.

It can also be used like this after a homogeneous mixture is provided. it is best to prepare their aqueous solutions beforehand.

After checking their swellability , is it possible to get their original texture and shape restored?

Does ethanol as solvent instead of DI water effect acrlyamide hydrogel formation ?

[@polymerscope6881]

Sure it does affect. The yield of the polymerization reaction is very low.

[@shivimaurya9631]

Sir the chemical used is not soluble in DI water bt in ethanol...so is there any way to get the polyacrlyamide gel little viscous gel using ethanol ?

[@polymerscope6881]

@@shivimaurya9631 The less you use crosslinker MBAAm, the more fluid it will be. For example, if you use the crosslinker at 0.2 mole percent of the monomer, you can get a viscous gel.

[@shivimaurya9631]

Thank you sir for the valuable suggestion😊

[@yogitabasnal]

those highy swellable are for what purpose? because as far as i know too much swellability is not prefered in vivo in humans because it puts too much pressure in the nearby tissue and increases tension. Are those swellable well suited for agriculture??

[@T--xo2uq]

Swelling is also bad for applications in batteries which is what I'm interested in... I've seen one paper that used cellulose as the copolymer, I'm trying to figure out the rest of their process, i.e. amount of AA monomer added.

[@yogitabasnal]

@@T--xo2uq ​​as far as I have observed, the hydrogels which are synthesized at higher temperatures are more swellable like at more than 60 degrees but the ones synthesized at 41 degree around are less swellable. Highly swellable can found applications in agriculture for sure

@@kunalsinha52 nitrogen purging is required to expel entrapped air/oxygen. Some people also use argon for the same. Its not mandatory though. I synthesized my hydrogels without nitrogen purging and they were synthesized really well.
