核壳结构填充的聚苯乙烯基复合材料介电性能研究
DIELECTRICS with high energy densities have drawn considerable interest due to their important applications in advanced electric power systems and electronic devices.Over past few years, many researchers have focused on polymer-based nanocomposites filled with high dielectric permittivity ceramic nanoparticles, expecting to obtain dielectrics which combine the high dielectric permittivity of ceramics and the high breakdown strength of polymers. Of widely investigated ceramic fillers, barium titanate (BaTi03, BT) may be the most important due to its ferroelectric property and high dielectric permittivity at room temperature. However, the realization of high energy storage via this strategy is still a severe challenge until now due to the interface incompatibility between the ceramic particles and the polymer matrix. Surface modification of fillers is the most effective way to improve the interface compatibility and enhance the dielectric properties.
