This study investigates the effect of dispersion of nanofiller reinforcement high performance polymer matrix to enhance the thermo-mechanical properties for bearing application. Polyetheretherketone (PEEK) matrix is reinforced with acid fucntionalized multiwalled carbon nanotubes (f-MWCNTs) and similar matrix was then reinforced with nano tungsten carbide (nano WC) to comparatively present their mechanical, thermal and morphological properties. The Nanocomposites were prepared via melt compounding method followed by injection moulding technique. The PEEK/f-MWCNTs nanocomposite exhibited better property enhancement than the PEEK/nano WC. Spectroscopical analysis confirmed the effectiveness of improved interfacial adhesion between PEEK and f-MWCNTs. Transmission Electron Microscope (TEM) micrograph depicted improved dispersion of f-MWCNTs in PEEK matrix than that of nano WC. Due to improved interfacial interaction between f-MWCNTs and PEEK, this resulting nanocomposite showed better mechanical, thermal and morphological properties than PEEK/nano WC. Due to ceramic nature of nano WC and higher density difference the agglomeration of particles occurred leading to lower properties.

不同填料增强对用于轴承应用的聚醚醚酮基纳米复合材料的影响
本研究调查了纳米填料增强高性能聚合物基体的分散对提高轴承应用的热机械性能的影响。聚醚醚酮 (PEEK) 基体用酸功能化多壁碳纳米管 (f-MWCNTs) 增强,然后类似的基体用纳米碳化钨 (纳米 WC) 增强,以比较呈现它们的机械、热和形态特性。纳米复合材料是通过熔融复合法和注射成型技术制备的。PEEK/f-MWCNTs 纳米复合材料比 PEEK/纳米 WC 表现出更好的性能增强。光谱分析证实了改善 PEEK 和 f-MWCNT 之间界面粘附的有效性。透射电子显微镜 (TEM) 显微照片描述了 f-MWCNTs 在 PEEK 基质中的分散性比纳米 WC 的分散性更高。由于 f-MWCNTs 和 PEEK 之间的界面相互作用得到改善,这种纳米复合材料显示出比 PEEK/纳米 WC 更好的机械、热和形态特性。由于纳米 WC 的陶瓷性质和更高的密度差异,粒子的团聚发生导致性能降低。
