Modulating superabsorbent polymer properties by adjusting the amphiphilicity

Frontiers in Chemistry, 2022
The role of amphiphilicity in polysaccharide-based superabsorbent polymers is paramount in determining material properties. While the performance of freeze-dried polymers is improved by maximizing hydrophilicity, this may not be the case for evaporative ...
