Special insulated wires beyond the conventional pure perfluoroalkoxy (PFA) polymers need to be developed to meet the increasing thermal management and mechanical performance requirements. Advanced PFA nanocomposites enhanced by inorganic fullerene tungsten sulfide (IF-WS2) nanoparticles have been fabricated by melt blending and hot press processes. Benchmarked against the PFA, the presence of IF-WS2 nanoparticles in the composites resulted in a maximum tensile strength of 21.35 MPa and a maximum elongation at break of 275%, which are 66% and 149% higher than those of pure PFA, respectively. The nanocomposites with 0.5 wt% IF-WS2 achieved a 17.5% increase in storage modulus, 26.8°C increase in the onset melt temperature, while 1 wt% IF-WS2 increased the glass transition temperature (Tg) by 3.4°C and the crystallinity (χc) by up to 34.4%. And when the additional amount of IF-WS2 nanomaterials is 0.25%, the best combination of performance is obtained.

低浓度无机富勒烯硫化钨纳米填料实现成本效益显着提高全氟烷氧基纳米复合材料的热力学和动态力学性能
需要开发超越传统纯全氟烷氧基 (PFA) 聚合物的特殊绝缘电线，以满足日益增长的热管理和机械性能要求。由无机富勒烯硫化钨 (IF-WS 2 ) 纳米粒子增强的高级 PFA 纳米复合材料已通过熔融共混和热压工艺制造。以 PFA 为基准，复合材料中 IF-WS 2纳米粒子的存在导致最大拉伸强度为 21.35 MPa，最大断裂伸长率为 275%，分别比纯 PFA 高 66% 和 149% . 含有 0.5 wt% IF-WS 2的纳米复合材料的储能模量增加了 17.5%，起始熔融温度增加了 26.8°C，而 1 wt% IF-WS 2增加玻璃化转变温度（Ť克）3.4℃，结晶度（χ Ç）高达34.4％。并且当IF-WS 2纳米材料的添加量为0.25%时，获得了最佳的性能组合。
