Silica Nanoparticles/Phenol Novalac Epoxy Resin Nanocomposites via Vacuum Shock Technique: Effect of Silica Nanoparticles on Curing Kinetic

Abstract

In this study, curing kinetic of phenol novalac epoxy resin with and without presence of silica nanoparticles (SN) was evaluated. In this case, the dynamic curing process was studied by usage of diffrential scanning calorimetry (DSC) with and without addition of silica nanoparticles in 4 heating rates, 2, 5, 10 and 15°C/min. Despite of that, from DSC analysis, the reaction exotherm was processed in order to obtain the reaction kinetic data such as the degree of reaction and the rate of reaction at different times and temperatures. Besides, a suitable model was proposed to explain the reaction kinetic data obtained from experimental section. Moreover, unknown parameters of this model were determined by a nonlinear Silica … S.
