Abstract
The novel solvent-free nanofluids (NFs) are prepared by assembling the hybrid Ti3C2Tx @SiCnws nanocores followed by grafting organosilane GPTES and polyether amine M2070. Then Ti3C2Tx @SiCnws NFs are incorporated into the PI/PTFE fabric liners composites (FC) along with tannic acid-PEI (TP) interfacial modification while the tribological performance of FC is systematically investigated. The results demonstrate that the tensile and interfacial strength of FC present effective growth resulting from tannic acid-PEI codeposition modification. Moreover, the addition of Ti3C2Tx @SiCnws NFs further enhances the thermal and mechanical properties of FC due to steric hindrance and entanglement of interfacial molecular chain. The tribological results prove that the improved interfacial adhesion, thermal properties and formation of load-bearing tribofilms are essential for enhanced tribological behaviors of FC.
