运用热刺激放电、表面电位衰减和电光效应的检测等手段，对主客体掺杂型非线性光学聚合物驻极体ＤＲ１／ＰＭＭＡ膜中空间和偶极电荷的相互作用特性进行了研究．结果表明，在极化后的样品中，被样品表面或体内的各类陷阱捕获的大部分空间电荷所处的陷阱能级高于极性生色团分子的定向排列产生的偶极电荷的束缚能级，空间电荷对偶极电荷有强烈的束缚作用．空间电荷衰减将导致材料内的电场分布发生变化，并引起极性生色团分子的松弛．空间电荷稳定性决定着偶极电荷的寿命 The interaction between the space and dipole charges in the host-guest doped nonlinear optical polymer electrets DR1 / PMMA was studied by means of thermal stimulation discharge, surface potential attenuation and electro-optic effect detection. The results show that most of the trapped charges trapped in the surface of the sample or trapped in the body are trapped higher than the dipole charge caused by the alignment of the polar chromophore molecules in the polarized sample Energy level, space charge on the dipole charge has a strong binding role. The decay of space charge will cause the electric field distribution in the material to change and cause the relaxation of the polar chromophore molecules. Space charge stability determines the life of the dipole charge
