主 题:BaTiO 3/PVDF dielectric constant dielectric loss
摘 要:A series of 0-3 composites of the polyvinylidene fluoride (PVDF) and BaTiO 3 was *** 3 was modified with titanate coupling *** dielectric properties and the interfacial interaction of composites by different preparation methods were examined and *** result shows that the relative dielectric constant ε of the composite prepared in solution has a maximum value at about 70% weight fraction of BaTiO 3 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 BaTiO 3 and the dielectric loss is comparatively *** dielectric properties of composites are improved by using a coupling agent.
