Abstract

Highlights: MXene@UiO-66-NH2 NFs were synthesized by electrostatic assembly followed by attaching with organic shell. MXene@UiO-66-NH2 NFs promoted the lubrication performance of FC significantly. Synergistic effect between MXene and UiO-66-NH2 was recognized during friction procedure. As-generated ZrO2 and MXene nanosheets participated in improving the lubricity and durability of transfer film. Abstract: The operational stability of self-lubricating fabric liners under harsh conditions faced serious challenge, and then the abrasion resistance and lubricating properties of fabric liners required further improvement urgently. Herein, the UiO-66-NH2 nanoparticles were uniformly anchored onto MXene nanosheets via electrostatic assembly to construct the 0D-2D hierarchical hybrid. Subsequently, the MXene@UiO-66-NH2 hybrids were further functionalized by grafting KH560 corona and M2070 canopy via covalent reaction to form MXene@UiO-66-NH2 nanofluids (NFs) with liquid-behavior. As a result, the friction and wear of PI/PTFE fabric composites presented an effective reduction with the introduction of MXene@UiO-66-NH2 NFs. In particular, significant synergistic effect between MXene and UiO-66-NH2 was recognized during sliding process, and comprehensive characterizations indicated that the MXene@UiO-66-NH2 NFs improved lubrication performance, load-bearing capacity and contributed to forming a robust tribofilm. Meanwhile, the innovative ionic shell structures endowed the MXene@UiO-66-NH2 NFs with outstanding dispersion stability in resin matrix and then maximized the enhancement effects.
