摘　　要： 本文主要对 PbTiO_3微粉在低含量下与环氧树脂复合的材料制备和特性进行了研究。通过对不同固化电场所制备样品的 XRD、介电频谱、光散射和紫外吸收光谱分析,结果表明:固化电场对复合材料的电学和光学性能有较大影响。并对电场作用的机理进行了探讨。 In this paper,preparation and properties of the fine composites of PT ultrafinepowders with epoxy in the lower PT content were investigated.The composite samples were ob-tained under applied bias electric fields during solidification.XRD,dielectric frequency spec-trum,light scattering and ultraviolet absorption of samples were measured.The results indicatedthat the influences of solidification field on electric and optical properties of the composites weresignificant.Furthermore,mechanism of electric fields applied on the composities was also dis-cussed.
