Mechanical properties of epoxy nanocomposites filled with melamine functionalized molybdenum disulfide

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.
