In this work, a melamine functionalized tungsten disulfide nanosheets (M-WS2) were fabricated and used as fillers to form epoxy EPR/M-WS2 nanocomposites. The effects of WS2 and M-WS2 loadings on the mechanical properties of epoxy composites were investigated and compared. With only addition of 0.5 wt% M-WS2, the fracture toughness (KIC) and fracture energy (GIC) of EPR/M-WS2 nanocomposites showed 68% and 94% improvement over the neat epoxy. Interestingly, the flexural modulus and strength of EPR was also increased with the introduction of M-WS2 fillers. These properties could result from the good dispersion and strong interfacial adhesion of M-WS2 fillers and the EPR matrix. Therefore, this work provides a facile way to produce of high-performance EP nanocomposites. |
