在本研究中,Q(t) 方法用于评估几种聚合物绝缘材料相对于电场和温度的累积电荷特性。通过量子化学计算获得的分子结构和能级,对使用 Q(t) 方法获得的累积电荷特性进行了分析。结果表明,组成单体形成的深陷阱深度阻碍了空穴和电子的迁移,并抑制了聚合物绝缘材料内部的电荷积累。此外,许多共轭双键与键形成牢固的平面结构,限制了由于键的弯曲和旋转而导致的分子内运动,从而表现出优异的耐热性。
In this study, the Q(t) method is used to evaluate the accumulated charge characteristics of several polymeric insulating materials with respect to the electric field and temperature. The accumulated charge characteristics obtained using the Q(t) method are analyzed in terms of their molecular structures and energy levels obtained through quantum chemical calculations. The results show that the deep trap depth formed by the constituent monomers hinders the migration of holes and electrons and suppresses charge accumulation inside the polymeric insulating material. Additionally, many conjugated double bonds form a strong planar structure with thebonds, which restricts intramolecular motion due to the bending and rotation of the bonds, and thus exhibits excellent heat resistance.
