| 摘 要： | 以乙二胺(EDA)为原料、三聚氰氯(CNC)为交联剂对制备的酸松弛猪皮胶原纤维(CF)进行氨基化改性,制备以胶原纤维为基质的吸附剂;并通过单因素实验法优化出了改性的最佳条件:反应物质的量比n(CNC)︰n(-NH2)=1.4,第一阶段冰水浴时间3 h,第二阶段反应温度为45℃,反应时间4 h,第三阶段反应温度为70℃,反应时间3 h;用水杨醛法测定了改性前后胶原纤维中氨基含量的变化,并用SEM、和FTIR分别对改性前后胶原纤维的组织形态、分子结构进行了表征。

| Abstract: | The aminated collagen fiber(ACF) was prepared by modifying collagen fiber(CF) with ethylenediamine and cynuric chloride as a crosslinking agent.The appropriate modification conditions were optimized by single factor experiment method: the reaction molar ratio n(CNC)︰n(-NH2) was 1.4,the reaction time of ice water bath was 3h,the temperature of the second phase was 45℃ and the reaction time was 4 h,the temperature of the third phase was 70 ℃ and the reaction time was 3h.The content of amino of collagen fiber and aminated collagen fiber were measured by the method of salicylaldehyde.The structures of collagen fiber and aminated collagen fiber were characterized and analyzed by SEM and FTIR respectively. |
