摘要：

The dielectric behavior of the [(Pb0.88Sm0.08)(Ti0.99Mn0.01)O-3]/polyetherketoneketone (PSTM/PEKK) ceramic/polymer composite is presented. The main contribution to the total dielectric relaxation response is due to the ceramic phase. Two important relaxation processes are observed, whose behavior suggest that the Jonscher's power law holds for the composite. The results are also explained considering the intra-cluster motion and inter-cluster exchange mechanisms, as proposed by the Dissado-Hill model.
