摘要
聚乳酸(PLA)是一种生物可降解高分子材料,具有很好的应用前景。本文以β-环糊精(β-CD)和聚乳酸为原料采用共沉淀法制备了β-环糊精和聚乳酸的包合物(β-CD-PLA IC),以包覆率为评价指标,通过平行实验考察了制备条件对包合过程的影响,结果表明,较佳条件为:环糊精和聚乳酸的投料比为20︰1((wt%)),搅拌速度为6000转/分钟,搅拌时间为30分钟。通过傅里叶变换红外(FT-IR)光谱和X射线衍射分析(XRD)对β-环糊精-聚乳酸包合物进行表征。
Polylactic acid(PLA) is a biodegradable polymer material with good application prospects. The inclusion complexes(ICs) between Polylactic acid and β-cyclodextrin(β-CD) were prepared by co-precipitation method. a higher encapsulation rate of inclusion products was obtained when the feeding ratio was 20︰1, stirring speed was 6 kr/min and the stirring time was 30 min. The structures ofβ-CD-PLA ICs were characterized by Fourier transform infrared(FT-IR)spectroscopy and X-ray diffraction(XRD).
