水辅助加工法制备聚丙撑碳酸酯/淀粉共混物
Poly(propylene carbonate)/Starch Blends Prepared by Water-assisted Processing
摘要
Abstract
Poly(propylene carbonate)(PPC)/starch blends with different blend morphologies were prepared by normal melt blending and water-assisted processing method.The effect of blend morphology on glass transition temperature(Tg), rheological and mechanical properties of PPC/starch blends was studied in details.The obtained results show that the starch remains its original granule structure when a normal melt blending is used.Interestingly, fine dispersed starch fibers are formed during extrusion of PPC/starch blends with the assistance of water.The formation of starch fibers in PPC matrix will increase the contact area between them leading to an enhanced interfacial interaction.Therefore, Tg, storage modulus and complex viscosity increase apparently.Additionally, when mass fraction of starch is 30%, there is a 67.7% increase in tensile modulus of PPC/starch blend.关键词
