초록

In this study, the curing and thermal decomposition properties of epoxy/silica composites fabricated by adding silica nanoparticles to epoxy resin were studied. The onset temperature, maximum exothermic temperature, and heat of reaction of epoxy/silica composites decreased as the silica content increased. The thermal decomposition behavior of cure epoxy/silica composites were analyzed using the Kissinger, Friedman, and Flynn-Wall-Ozawa methods based on the isoconversional method. As a result, the activation energy of thermal decomposition increased and the reaction of thermal decomposition was stabilized by addition of silica nanoparticles. However, when the silica content was 30 wt%, the activation energy was decreased due to the excessive addition of silica, which causes the agglomeration of silica particles in the epoxy resin.
