Water absorbent polymers are essential in uses ranging from agriculture to personal hygiene. Explore how hydrogen bonding allows hydrophilic polymers to absorb several hundred times their own weight in water. Students investigate how a small change in chemical structure has a dramatic effect on the rates of water absorption for sodium polyacrylate, polyacrylamide, and polyacrylate/polyacrylamide copolymer. Students also investigate the effects of solute concentration on the osmosis of water into and out of these polymers and then extend that learning to design a diaper that meets real-world requirements....
