| 摘 要： | 利用溶液浇铸法制备了聚己内酯（PCL）/聚乙烯基吡咯烷酮（PVP）共混物膜,通过测试膜的表面接触角、吸水率,研究了共混膜的亲水性能;通过测试膜的断裂伸长率和断裂强度,研究了共混膜的力学性能;用XRD对膜进行表征,研究了共混膜的结构.结果表明：PVP的加入对PCL的结晶度有一定影响;随着PVP质量分数的增加,水在PCL/PVP膜的表面接触角逐渐减小,吸水率逐渐增大;适当比例的PVP含量有助于增强PCL的力学性能.

| Abstract: | Polycaprolactone(PCL)/Polyvinylpyrrolidone(PVP) blend films were prepared by using the solvent casting method.Then the hydrophobic properties of the blends was studied by testing the surface contact angle and water absorption of the films;the mechanical properties of the blends was studied by testing the films' breaking strength and elongation at break;and the structure of the blend was studied by characterizing the films with XRD.The results showed that: the addition of PVP has some influence on the crysta... |
