Abstract

Abstract: PA6/SiO2 nanocomposites were prepared by in-situ polymerization. The interfacial compatibility between nano-SiO2 and PA6 matrix was characterized by mechanical experiment, SEM, and DSC. It showed that The interfacial parameters B for PA6/modified SiO2 was larger than that for PA6/unmodified SiO2. SEM observation showed that the introduction of SiO2 changed the microstructure of the materials. Better interfacial binding was observed between PA6 matrix and modified SiO2, which resulted in a flexible interface layer favorable to the crystallization of the PA6.

Key words: Polyamide 6, silicon dioxide, nanocomposites, interface
