摘　　要：合成了一种由戊二醛交联的壳聚糖与聚醚形成的半互穿聚合物网络的水凝胶，用ＤＳＣ法并结合ＩＲ光谱研究了该水凝胶中水的状态及水与聚合网络间的相互作用。The chitosan/polyether semi-IPN hydrogel based on glutaraldehyde-crosslinked chitosan and polyether interpenetrating polymer network(semi-IPN) has been prepared.The physical state of water in the semi-IPN hydrogel swollen in distilled water or PH= l.25 buffer solution was studied with differential scanning calorimetry(DSC).Infrared spectroscopy was also used to provide information on the interactions of water molecules with the gel network.
