Synergy of B₄C@MoS₂ hybrid for significantly improved mechanical and tribological properties of PI/PTFE fabric composites

Abstract

In this study, a hierarchical B 4 C@MoS 2 hybrid is constructed by growing MoS 2 nanoflowers onto micro B 4 C (boron carbide) surface via an in situ hydrothermal process. Thereinto, the PDA/PEI (polydopamine/polyethyleneimine) codeposition coating covers over the micro B 4 C surface to serve as the interfacial interlayer responsible for assembling the B 4 C and MoS 2 together strongly.

Effect of homologous molecular crosslinking on the tribological properties of PTFE composites

“…2,3 However, the limitations of PTFE, such as poor wear resistance, severe creep deformation, and easy wear, severely restrict its application as engineering plastic in actual production. To enhance the mechanical and tribological characteristics of PTFE, researchers have proposed techniques like the use of surface modification, [4][5][6][7] filling modification, [8][9][10] and blending modification. 8,[11][12][13] PTFE matrix composites were also obtained from the original binary composites, 3,14 the later multicomponent composites, 8,[15][16][17] and combinations of both methods.…”

Investigation of the way to enhance the synergistic effect between polyimide and graphene on the tribological performance of polytetrafluoroethylene composites

“…Polytetrafluoroethylene and Polyimide are two commonly used polymer self‐lubricating materials because of their excellent tribological performance. [ 10,13,15 ] The mixture of PTFE and PI is a typical polymer blending system. PTFE takes excellent antifriction performance but poor wear resistance.…”
