制备了微球状交联壳聚糖并合成了交联壳聚糖(AECTS) Co配聚物。用FTIR、WXRD、TGA和DSC等对配聚物进行了结构表征。结果表明:Co2+与AECTS中的氨基、羟基发生配位而被吸附;树脂与Co2+配位后,结晶度下降、热稳定性降低。
Microsphere cross-linked chitosan was prepared and cross-linked AECTS co-polymer was synthesized. Homopolymers were characterized by FTIR, WXRD, TGA and DSC. The results showed that Co2 + was adsorbed on the amino and hydroxyl groups of AECTS and was adsorbed. When the resin was coordinated with Co2 +, the crystallinity decreased and the thermal stability decreased.
