Halloysite–gold core–shell nanosystem synergistically enhances thermal conductivity and mechanical properties to optimize the wear-resistance of a pheonlic-PBO/PTFE textile composite liner

Abstract Polymer-textile liner composites have potential applications in aerospace for reducing the abrasion damage of moving parts during operation owing to their self-lubrication, light weight, and high loading capacity. Herein, Au nanoparticles (AuNPs) are successfully loaded into lumen halloysite nanotubes (HNTs) construct an HNTs–Au peasecod core–shell nanosystem optimize wear resistance phenolic resin-based poly(p-phenylene benzobisoxazole) (PBO)/polytetrafluoroethylene (PTFE) textile composites. Transmission electron microscope (TEM) characterization reveals that AuNPs well-dispersed inside HNTs, with average diameter 6–9 nm. The anti-wear performance HNTs Au-reinforced PBO/PTFE is evaluated using a pin-on-disk friction tester at 100 MPa. Evidently, addition induces 27.9% decrease rate Possible mechanisms proposed based on analyzed results worn surface morphology cross-section tribofilm obtained by focused ion beam transmission microscopy.
