摘要	The increasingly harsh service condition of lubricating coatings presents a more pressing demand for improving performance. Herein, octa-amino polyhedral oligomeric silsesquioxane (POSS) were covalently grafted onto polyimide (PI) matrix. The effect of POSS on the mechanical properties of the PI-based composite coatings and the tribological properties of PI/PTFE based lubricating coatings before and after modification were investigated. As expected, compared with the pure PI, the POSS-PI nano-materials exhibited 31.6% and 32.7% enhancements in tensile strength and nano-hardness without discernable decrease in breaking elongation. Additionally, the wear rate significantly decreased by 54.9% with the addition of OPOSS. The enhancement of wear resistance could be attributed to the improved cohesion strength and load-bearing capacity of the PI/PTFE composite coating reinforced by POSS.
