Abstract :
Thermally stimulated current spectroscopy was applied to investigate the influence of structural change and interfacial state on the electrical properties of epoxy composites cured with acid-anhydride. A overabundantly added hardener separated a β peak near 10[°C] into two peaks of β1(10°C) and β2(20°C). Filling with an inorganic filler increased the magnitude of TSC between the α and β peaks and lowered T g. Silan coupling agents on the filler improved interfacial deformation, decreasing TSC
