摘要
Abstract
The toughened poly(3-hydroxybutyrate-co-3-hydroxyvalerate)(PHBV)/polypropylene carbonate(PPC)blending films were prepared through solid-phase stretching and then characterized by using universal tensile testing ma-chine,small-angle/wide-angle X-ray scattering instrument,SEM,and DSC.The PHBV/PPC blending films exhibited an increase in elongation at break by about 66%and in tensile strength by 642.9%at a stretching temperature of 55 ºC,a stretching rate of 300 mm/min,and a stretching ratio 3.The degree of orientation of the blending films was increased from 0.88%to 38.96%at a stretching ratio of 3.This effectively promotes the crystallization of PHBV and generates a positive effect on its durability of PHBV,resulting in more stable performance.The toughness of the unstretched blend-ing film decreased by 94.8%,whereas there was only a reduction by 46%in the toughness of the blending film at a stretching ratio of 3.关键词
