Hello,
I want to dissolve PVA in water to get a final concentration of 10%wt. My PVA is 90%+ hydrolyzed from sigma.
At the moment, I have just added the PVA (all at once) to water, but I get these itty lumps in my solution, I have thought about first dissolving the PVA in water under magnetic stirrinh for 2h and then heating it to 90C under stirring to prevent further polymerisation. I want to process the PVA to an all solid electrolyte for supercaps

Thanks,
it works pretty well, when I first let the PVA swell while stirring the solution (20C). After this I ultrasonicate the whole thing, which will remove these itty lumps. With subsequencial heating I will dissolve the pva
