摘　　要：以N,N-二甲基甲酰胺和二氯甲烷为溶剂,聚乳酸和聚碳酸丁二醇酯作为基体材料,在此基础上加入壳聚糖并负载茶多酚,经油浴恒温溶解。通过静电纺丝机制备出PBC/PLA/CS/TP完全可生物降解薄膜,使用傅立叶红外分析、差示扫描量热法、热重分析研究CS/TP对共混膜热稳定性和结构特性的影响,并测试薄膜的机械性能。通过实验得出,制得的可降解复合纤维膜具有良好的相容性且随着CS和TP含量的增加,膜的热稳定性和机械性能得到进一步的提升。Using N,N-dimethylformamide and dichloromethane as a solvent,polylactic acid and polybutylene carbonate as matrix materials,adding chitosan and tea polyphenols and dissolved in a constant temperature oil bath.PBC/PLA/CS/TP fully biodegradable film was prepared by electrospinning machine,and the CS-to-blend film was studied by Fourier infrared analysis,differential scanning calorimetry,and thermogravimetric analysis thermal stability and structural characteristics,and test the mechanical properties of the film.Through experiments,it is concluded that the prepared tea polyphenol modified PBC/PLA/CS degradable composite fiber membrane has good compatibility.With the increase of CS and tea polyphenol content,the thermal stability and mechanical properties of the membrane are further improved.
