两种高Tg非线性光学聚合物母体及掺杂、极化的研究

Two Novel Guest-host Polymers with High Tg's For Nonlinear Optics and Poling

利用具有非线性光学活性的对硝基苯胺掺杂高玻璃化转变温度的聚芳醚砜(PES-C)和聚芳醚酮(PEK-C),得到了两种掺杂含量较高的掺杂型非线性光学聚合物体系。电晕极化表明较高的取向和较慢的松驰。

Two guest-host systems nonlinear optical polymers of p-nitroaniline and high glass transition temperature host polymer polyarylethersulfone (PES-C) and polyaryletherketone (PEK-C) have been investigated. Homogeneous thin films of PES-C and PEK-C were obstained with the NLO molecules having concentrations up to 20% and the poled polymers exhibited high orientational order and slow relax behavior.
