摘要

Abstract

Three types of high-density polyethylene (HDPE) with different molecular weights (high

medium and low) were adopted to evaluate the influence of matrix molecular weight on the structure-property relation of injection-molded HDPE/mica composites through a combination of SEM

2d-WAXS

DSC

DMA and tensile testing. Various structural factors including orientation

filler dispersion

interfacial interaction between HDPE and mica

etc

which can impact the macroscopic mechanics

were compared in detail among the three HDPE/mica composites. The transcrystallization of HDPE on the mica surface was observed and it exhibited strong matrix molecular weight dependence. Obvious transcrystalline structure was found in the composite with low molecular weight HDPE

whereas it was hard to be detected in the composites with increased HDPE molecular weight. The best reinforcement effect in the composite with low molecular weight HDPE can be understood as mainly due to substantially improved interfacial adhesion between matrix and mica filler

which arises from the transcrystallization mechanism.
