非线性光学聚合物的介电弛豫行为不再遵从Deby弛豫行为.为描述α弛豫标度,认为除了弛豫时间和介电弛豫强度,两个分别描述低频和高频介电特性的参量m和n是必要的.给出了用HN函数表示的复介电的表达式,并用HN模型函数模拟确定出了几种非线性聚合物的标度参量m和n.

The dielectric relaxation behavior of nonlinear optical polymers does not follow the Debye behavior.To describe the scaling of the α relaxation,two shape parameters m and n describing the low-and high-frequency wings of the relaxation are necessary,besides their relaxation time and the dielectric strength.The scaling parameters m and n of several NLO polymers were determined by using Havriliak and Negami (HN) model function.
