摘要

This study aims to investigate the interfacial crystallization between glass fiber (GF) and polypropylene (PP) by micro-injection molding. Three different kinds of transcrystallinity (TC) were formed at different conditions by different formation mechanisms. The virgin GF could form the TC by aligning the adjacent molecules to parallel with the GF surface, while the modified GF (M-GF) could induce the TC directly on its surface. Furthermore, the M-GF reduced the number of nano-voids between the GF and iPP, characterized by X-ray scattering technique. When -nucleation agents (-NA) were added, a novel net-coating layer was first discovered on the M-GF surface. This structure may be caused by the self-organization of -NA and leads to some unique intensity streaks in SAXS patterns. Based on the experimental results, a schematic model was proposed.
