✦ Synopsis

The swelling behavior of the complex film formed from pectin and chitosan was studied. The swelling degree increased sharply in the case of p H less than 2 and larger than 7. The swelling mechanisms of the complex film in acidic and alkaline medium are discussed, respectively. Moreover, the swelling degree could be modulated by means of the weight ratio of pectin to chitosan and the original weight concentration of pectin aqueous solution.

## Abstract This study investigates the improved swelling behavior of chitosan/poly(acrylic acid) complex by solvent (methanol, ethanol, and acetone) extraction. The complex is developed by photoinitiated free‐radical polymerization of acrylic acid in the presence of chitosan. The swelling ratio of

The thermoelastic behavior and equilibrium stress-strain properties of chitosan films lightly crosslinked with gluteraldehyde and swollen with water were studied. Precautions were taken to preclude changes in the swelling ratio of swollen sample films during the experiment. The results indicate that

## 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,
