## Abstract In this paper, a novel composite hydrogel was prepared by the use of dialdehyde konjac glucomannan (DAK) as macromolecular crossβlinking agent for chitosan (CS). This biocompatible material crossβlinks and gels in minutes. The structure and morphology were characterized by various analy
## Abstract Polyelectrolyte complex (PEC) hydrogels composed of various weight ratios of chitosan and hyaluronic acid were prepared. The PEC hydrogels were formed by the reaction of the oppositely charged chitosan polymers. The PEC films swelled in water rapidly, reaching equilibrium within 30 min,
