电光聚合物材料通常采用带栅极的电晕极化技术进行处理。本文通过求解泊松方程分析电晕极化过程中聚合物内外的电场分布。将平衡状态与样品表面电位相联系,得到了平衡状态时的外部极化电流。在假定自由空间电荷的影响可以忽略的情况下,得出了外部极化电流与内部极化状态之间的简单关系。这可以在一定程度上反映极化取向的状态。 Electro-photopolymer materials are typically processed using a corona-polarization technique with a gate. In this paper, the Poisson equation is used to analyze the electric field distribution inside and outside the polymer during corona polarization. The equilibrium state is related to the surface potential of the sample, and the external polarization current at equilibrium is obtained. Given the negligible influence of free-space charge, a simple relationship between the external polarization current and the internal polarization state is derived. This can to some extent reflect the state of polarization orientation.
