Synthesis and performances of Fe2O3/PA-6 nanocomposite fiber

Abstract: A novel fiber consisted of nano-Fe2O3 particles/polyamide-6 (PA-6) nanocomposite has been prepared successfully. The thermal stability of the composite material was enhanced about 16 °C (from 440 °C to 456 °C) by the addition of Fe2O3 nanoparticles with 15.0% content (part per hundred parts of resin). In situ polymerization can make the materials possess homogeneously dispersed nanoparticles. The Fe2O3 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. [Copyright &y& Elsevier]
