Abstract
A series of 0–3 composites of the polyvinylidene fluoride (PVDF) and BaTiO3 was prepared. BaTiO3 was modified with titanate coupling agent. The dielectric properties and the interfacial interaction of composites by different preparation methods were examined and compared. The result shows that the relative dielectric constant ∈ of the composite prepared in solution has a maximum value at about 70% weight fraction of BaTiO3 and the dielectric loss tanδ increases rapidly when the fraction exceeds 70%. For the composite prepared in melt, the relative dielectric constant ε almost reaches a maximum value at about 60% weight fraction of BaTiO3 and the dielectric loss is comparatively lower. The dielectric properties of composites are improved by using a coupling agent.
