Synergistic effects of bioprotein decoration and WS2 @Ti3C2 nanohybrids on the interfacial and tribological performance of PPS/PTFE fabric composites

Developing high-performance fabric composites with comprehensive properties is of paramount importance to broaden their application areas. In this work, a novel technique was studied to enhance interfacial adhesion via the adsorption of the complex amphiphilic biopolymer protein onto the surface of PPS/PTFE fabrics. Additionally, WS2 @Ti3C2 nanohybrids with heterostructures were synthesized, and the distinctive hierarchical microstructure facilitated the multiple reinforcement of the fabric composites. The results suggest that the decoration of BSA offers reaction sites with the phenolic resin and enhances the interfacial performance. Compared to the pure hybrid fabric composites, the tensile and bonding strength of the reinforced hybrid fabric composites are increased by 35.91% and 68.51%. Moreover, the wear rate of the reinforced hybrid fabric composites is decreased by 59.3%.
