It is generally known that the dielectric constant (K) of the BaTiO3/epoxy composites increases with improvement of the dispersion of BaTiO3 particles in the epoxy matrix that comes from adding surfactant. The influences of surfactant addition on the dielectric properties of the BaTiO3/epoxy composites are reported in the present study. The dielectric constant of the BaTiO3/epoxy composites is not significantly affected by the surfactant addition. However, the temperature coefficient of capacitance increases and the peel strength decreases as the amount of added surfactant increases. The influences of surfactant addition on the dielectric properties of the neat epoxy are also very similar to those of the BaTiO3/epoxy composites. The residual surfactant in the BaTiO3/epoxy composites affects the temperature coefficient of capacitance and the peel strength of the epoxy matrix, which in turn affects the temperature coefficient of capacitance and the peel strength of the BaTiO3/epoxy composites.
