Glutraraldehyde(GA), epichlorohydrin(ECH), toluene diisocyanate(TDl) and hexamenthylene diisocyanate(HDI) are applied to crosslink CMCS respectively to get four aquagel: CMCS-GA , CMCS-ECH > CMCS-TDI and CMCS-HDI.

• 以戊二醛(GA)、环氧氯丙烷(ECH)、甲苯-2，4-二异氰酸酯(TDI)和六亚甲基二异氰酸酯(HDI)对羧甲基壳聚糖进行交联制备出水凝胶。 GA与CMCS用量摩尔为0.；2：1时，所得的水凝胶得到较大的溶胀度11
