摘    要:制备出新型两亲性可生物降解聚合物膜.膜由3种成分组成,其一为新型的可生物降解交联剂,用以调节膜的降解速率;其二为亲水单体乙烯基吡咯烷酮,用以提高材料的亲水性,并最终提高材料与细胞的相互作用;其三为羟乙基甲基丙烯酸酯封端聚乳酸,用以调节膜的机械强度,通过傅里叶红外光谱(FTIR)和核磁共振(NMR)分析,结果表明,成功合成可生物降解的交联剂及大分子单体HEMA-PLA,并制备出可应用于组织工程的新型膜材料.

关 键 词:交联剂  乙烯基吡咯烷酮  羟乙基甲基丙烯酸酯封端聚乳酸    两亲性  生物降解

Abstract:A novel kind of amphiphilic and biodegradable films were developed. The film mainly is composed of three components: a novel biodegradable crosslinking agent, which is used to adjust the degradable rate of the film;a hydrophilic monomer N-vinyl pyrrolidone (NVP), which is used to improve the material's hydrophilicity, and ultimately improve the interaction between material and cells;a macromonomer 2-hydroxyethyl methacrylate-terminated polylactide acid (HEMA-PLA), which is used to control the film's mechanical strength. These films hopefully will have practical applications in tissue engineering.
Keywords:crosslinking agent  NVP  HEMA-PLA  film  amphiphilic  biodegradable
