Polydicyclopentadiene (PDCPD)/hydroxylated barium titanate (BTOH) and PDCPD/norbornene functionalized barium titanate (BTNA) composites have been in situ prepared by frontal ring-opening metathesis polymerization (ROMP). Dynamic mechanical analysis (DMA) results show that the glass transition temperature (Tg) of PDCPD/BTNA composites was higher than that of PDCPD/BTOH, which was mainly due to the enhanced interfacial affinity between BTNA and PDCPD matrix. The PDCPD/BTNA composites exhibited high dielectric constant (20.2 at 100 Hz) due to the interfacial polarization between PDCPD and BTNA, while the non-conductive norbornene groups prevented leakage current generation and supported low loss tangent (0.017).
