Research into the Preparation and Performance of Hydrotalcite/ MC Nylon 6 by In Situ Intercalation Polymerization

Article Preview

Abstract:

Hydrotalcite (LDHs) / MC nylon 6 composites were prepared by in- situ intercalation polymerization, followed by morphology and mechanical properties’ characterization of composites. FTIR shows that chemical structure of the molecular chain of the MC nylon 6 is not changed with adding hydrotalcite; SEM reveales that LDHs (2.5, wt-%) has good dispersion and compatibility in the MC nylon 6 matrixes; but when the amount of LDHs is excessive, the composites show obvious phase separation phenomenon. Hydrotalcite can significantly improve the mechanical properties of the composites. When the amount of hydrotalcite reaches 2.5% (wt-%), the composite has best comprehensive mechanical performance. Comparing with untreated MCPA6, the tensile strength and notched Izod impact strength are respectively increased by 68 % and 53 %.
