제목 WS2nanosheets: an advanced reinforcement for epoxy composites​
초록 We present atwo-dimensional WS2-based material as a reinforcement additive toproduce thermally stable, mechanically strong, and light-weight epoxy (EP)composites. An aqueous melamine solution was used to exfoliate the bulk WS2into nanosheets while simultaneously functionalizing them to obtain N-WS2nanoplatelets. The results demonstrated that the surface free energy of EPcomposites had been significantly increased after the incorporation of N-WS2nanosheets into EP matrix and increases with increased loading of N-WS2nanosheets up to a maximum value of 52.38 mJ.m-2 for the compositecontaining 0.5 wt.% of N-WS2 nanosheets, suggesting stronger interfacial interaction between EP and N-WS2.The mechanical properties of the EP composites were analyzed and demonstrated 57%,108%, 40%, and 18% improvements in fracture toughness, fracture energy,flexural strength, and flexural modulus, respectively, for the composite comprising0.5 wt.% N-WS2 nanosheets.
