Nanomechanical Properties of Core-Shell Structured Ni@NiO Nanoparticles Reinforced Epoxy Nanocomposites

Abstract:

Epoxy resin (EP) nanocomposites reinforced with different contents of core-shell structured Ni@NiO nanoparticles (NPs) were fabricated by using a surface wetting method. The nanoindentation and nanoscratch properties of Ni@NiO/EP nanocomposites were comparatively studied based on nanoindentation technique. Results revealed that 5 wt.% content of Ni@NiO NPs was the optimal concentration for Ni@NiO/EP composites to obtain the best improvement of nanomechanical properties. In comparison with pristine EP, the highest enhancements of hardness and elastic modulus of 5 wt.% Ni@NiO/EP nanocomposites were increased by 37.8% and 16.3%, respectively.
