Synthesis and performances of Fe_2O_3/PA-6 nanocomposite fiber

摘要

A novel fiber consisted of nano-Fe_2O_3 particles/polyamide-6 (PA-6) nanocomposite has been prepared successfully. The thermal stability of the composite material was enhanced about 16℃ (from 440℃ to 456℃) by the addition of Fe_2O_3 nanoparticles with 15.0% content (part per hundred parts of resin). In situ polymerization can make the materials possess homogeneously dispersed nanoparticles. The Fe_2O_3 reinforced materials processed by melt spinning displayed improved tensile modulus compared to similarly processed pure polyamide-6, the improvements of tensile strength and modulus were 21.22% and 112%, respectively. Moreover, this fiber has the property of ultraviolet and visible light absorption.
