摘要：
Polyamide 6 (PA6)/magnesium hydroxide (MH) nanoparticles composites have been prepared by in situ polymerization of c-caprolactam in the presence of pristine MH and gamma-aminopropyl-triethoxysilan (KH550) grafted MHs (MMH). Compared with pure PA6, the tensile strength and elongation at break of PA6/MH and PA6/MMH composites shown obvious increasement and attain maximum at loading of 3 wt% MHs. The tensile strength and elongations at break of PA6/MMH composites exhibited notably enhancement contrast with that of PA6/MH composites. Comparing with PA6/MH composites, the izod impact strength of PA6/MMH composites were also improved. Scanning electron microscopy (SEM) shown that MMH particles were homogeneous dispersed in PA6 matrix due to the surface modification of grafting KH550.
