I am looking to purchase sodium polyacrylate (a hydrogel) but it comes only in powder form. Is there an intrinsic property of the compound that prevents them from forming sheets out of the substance? I am not sure how to proceed in creating my own sheet of the substance other then synthesizing it from scratch in a mold.
In the end I am trying to make my own water beads, that swell in water.
Thanks for any tips/suggestions.
