Wetting Method

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.

Abstract The work presented and reviewed in this paper leads to the following conclusions: (a) The kinetics of creep in HIPS containing 0.2 µm diameter core-shell rubber particles are similar to those in more conventional HIPS containing larger multiple-inclusion particles. Both deform by multiple crazing. (b) Comparisons of mechanical properties should be made on the basis of equal rubber volume fractions ϕ rather than equal elastomer contents. (c) The kinetics of creep in rubber-toughened PMMA, also containing small core-shell particles, are quite different from those of HIPS. Deformation occurs by shear yielding accompanied by a small volume increase which is probably due to cavitation in the rubber particles. (d) The dependence of deformation rates upon applied stress and temperature is well described by the Eyring model for activated flow. (e) Analysis based on the Eyring slopes can be used to compare stress concentration factors γ in toughened plastics. In polymers that deform by shear yielding, absolute values of γ can be obtained by comparison of data from toughened and untoughened plastics. Difficulties remain in applying a similar approach to polymers that deform by multiple crazing. (f) The rate-determining step occurs in regions of maximum stress concentration in HIPS and appears to be identified with initiation of crazing. (g) The rate-determining step in toughened polymers that deform by shear yield is not associated with regions of maximum stress concentration.
