聚5羧基吲哚聚乙交酯可降解导电共聚物的合成与表征
DOI: 10.3969/j.issn.1671-7627.2012.02.021, PP. 100-105
Keywords: 聚5羧基吲哚,聚乙交酯,导电聚合物,降解作用,生物相容性
Abstract:
以n,n′-二环己基碳化二亚胺（dcc）为脱水剂、4-二甲氨基吡啶（dmap）为催化剂,通过低温缩聚法合成可生物降解并导电的聚5-羧基吲哚（pica）与聚乙交酯（pga）的共聚物。合成的产物采用红外光谱仪（ft-ir）、核磁共振氢谱仪（1hnmr）、质谱仪（ms）进行表征。结果表明：产物经25d降解了41.7%,测得掺杂的共聚物电导率为9.1×10-4s/cm。将乳仓鼠肾细胞（bhk21）黏附于合成的齐聚物膜上，细胞增殖生长效果明显。
