三甲基壳聚糖季铵盐水凝胶的制备及性能
Preparation and properties of N,N,N-trimethyl chitosan quaternary ammonium hydrogel
摘要
Abstract
N,N,N-trimethyl chitosan quaternary ammonium hydrogel（TMCG）was prepared in the mild condition by using reactive divinyl sulfone（DVS）as a cross-linking agent.The swelling behavior and mechanical properties of TMCG were investigated,together with the water state and distribution in swelling TMCG.The results show that TMCG is an ionic responsive hydrogel with fast swelling rate and high swelling ratio,the maximum equilibrium swelling ratio approaches to 40 times.TMCG has significant ionic responsiveness.Water molecules exist in the TMCG by three different forms of state as free water,freezing bound water,non-freezing bound water,and non-freezing bound water content increases with the increase of cross-linking agent.TMCG has good mechanical properties,the maximum tensile strength is up to 13.82 MPa,and the highest elongation at break is up to 135.3%.关键词
