摘要/Abstract

摘要： 将聚丙烯(PP)和纳米碳纤维(CNF)共混后，通过双螺杆挤出制备成不同组份的复合粒料，采用注射成型加工制备实体和发泡试样，研究不同CNF含量对PP基体复合材料性能的影响。结果表明，随着CNF含量的增加，微孔样品中的孔径显著的减小同时泡孔密度增加;注射成型的样品中，添加CNF后的模量和拉伸强度略微降低，但微孔注塑的PP/CNF复合材料的性能呈现出相反的效果。

Abstract: The polypropylene (PP)/carbon nanofiber(CNF) composites were prepared by a melt-blending method, followed by microcellular injection molding, and the effect of CNF on the properties of the composites. The results indicated that the microporous size decreased significantly with an increase of CNF content, but themicroporous density increased. Moreover, the tensile strength and modulus of conventional injection-molded composite samplesdecreased slightly in the presence of CNF, but the microcellular injection-molded ones seemed to present an opposite trend.
