摘要

以壳聚糖、丙烯酰胺(AM)和二甲基二烯丙基氯化铵(DMDACC)为原料，N, N-亚甲基双丙烯酰胺(MBA)为交联剂，经60Co ?-射线辐照，制备了丙烯基类单体-壳聚糖共聚物水凝胶，并研究了MBA的用量对丙烯基类单体-壳聚糖共聚物水凝胶吸水性能和保水性能的影响。结果表明，在吸收剂量为2 kGy的条件下，MBA用量较低时，随着MBA用量的提高，水凝胶的平衡吸水率反而下降；而MBA用量较高时，水凝胶的平衡吸水率受MBA用量的影响较小；凝胶吸水率随着溶胀时间的延长而增加；水凝胶在溶胀初期的溶胀动力学可用non-Fickian扩散定律来描述；随着交联剂MBA用量的逐渐增加，水凝胶的初始失水率逐渐增大，而最大失水率逐渐下降。

Abstract

Using γ-ray irradiation method, propenyl monomer-chitosan copolymer hydrogel was synthesized with chitosan, acrylamide (AM), diallyl dimethyl ammonium chloride (DMDAAC), and N, N-methylene-bis- acrylamide as crosslinking agent. The influence of crosslinker MBA amount on water absorption and retention properties of propenyl monomer-chitosan copolymer hydrogel was studied. The results showed when the amount of MBA was lower with the absorbed dose of 2 kGy, equilibrium water absorption decreased with the increasing MBAs; when the amount of MBA was higher, equilibrium water absorption was less affected by MBA; the swelling ratio of hydrogel increased with time; non-Fickian diffusion law could be used to describe swelling kinetics of hydrogel at initial stage; with the increase of the MBA amount, initial water loss rate of the hydrogel increased, however, the maximum loss rate decreased.Cited
