Controlling Structures and Properties of NaCl‐Containing Alginate/Polyacrylamide Tough Hydrogels via a One‐Pot Process

Chemistry – A European Journal, EarlyView.
NaCl‐incorporated alginate/polyacrylamide tough hydrogels are prepared through a facile one‐pot strategy that enables direct ion incorporation during network formation. Compared with conventional soaking, this approach reduces diffusion‐limited ion gradients and provides a more spatially consistent ion distribution.
