Abstract

In this work, a melamine functionalized molybdenum disulfide (M-MoS₂) was prepared and used as fillers to form epoxy (EP)/MoS₂ nanocomposites. The effects of molybdenum disulfide (MoS₂) and melamine functionalized molybdenum disulfide (M-MoS₂) loading on the mechanical properties of epoxy composites were investigated and compared. With only addition of 0.8 wt% M-MoS₂, the tensile strength and modulus of EP/M-MoS₂ nanocomposites showed 4.5 and 4.0 times increase over the neat epoxy. Interestingly, the elongation at break value of EP was also increased with the introduction of M-MoS₂ fillers. These properties could result from the good dispersion and strong interfacial adhesion of M-MoS₂ fillers and the EP matrix. Therefore, this work provides a facile way to produce of high-performance EP nanocomposites.
