报道了一种简单有效的制备聚醚醚酮（PEEK）/无机富勒烯硫化钨（IF-WS 2）纳米复合材料的方法。我们用电子显微镜观察了纳米复合材料的形貌和结构特征，用FTIR和XPS研究了PEEK和IF-WS 2之间的化学界面结合。我们证明，所得的PEEK/IF-WS 2纳米复合材料的热导率增加了190%，降解温度提高了50 °C，强度和硬度略有改善。纯PEEK和PEEK/IF-WS 2纳米复合材料的降解活化能分别从64 kJ/mol增加到76 kJ/mol，这归因于PEEK基体和IF-WS 2纳米颗粒之间的协同界面。机械和热性能的增强将显着扩大PEEK基纳米复合材料的能力，使其应用于导热性和稳定性很重要的领域。
We report a simple and effective method to fabricate PEEK (poly ether ether ketone)/IF-WS2(Inorganic Fullerene Tungsten Sulphide) nanocomposites with IF-WS2content up to 8 wt%. We have used electron microscopies to characterise the morphology and structural features of the nancomposites, and FTIR and XPS to show that some chemical interface bondings were formed between the PEEK and IF-WS2. We demonstrate that the resulting PEEK/IF-WS2nanocomposites showed an extraordinary 190% increase in thermal conductivity, 50 °C higher in degradation temperature, and mild improvements in strength and hardness. The increased degradation activation energy from 64 to 76 kJ/mol for neat PEEK and PEEK/IF-WS2nanocomposites, respectively, is attributed to the synergistic interface between the PEEK matrix and IF-WS2nanoparticles. The enhancements in both the mechanical and thermal properties will significantly expand the capacities of PEEK-based nanocomposites towards applications where thermal conductivity and stability are important.
