摘　　要：采用旋涂的方法制备了主客掺杂 15 % NAEC/PMMA有机聚合物薄膜 ,通过测量其 DSC曲线来确定玻璃化温度 ,并在此温度对其进行电晕极化。测量了薄膜极化前后以及退极化后的紫外 -可见吸收光谱 ,研究了NAEC/PMMA薄膜中客体生色团的电极化取向以及薄膜的二阶非线性效应。With the method of spin coating the guest host organic polymer NAEC/PMMA thin films in which the weight percent of NAEC is 15% were prepared.The films were poled with corona onset poling method at the glass transition temperature determined by the differential scanning calorimeter (DSC).The absorbtion spectra of the unpoled and poled film were measured.The orientation order of the chromophore molecules in polymer NAEC/PMMA thin film and the second order nonlinear optical effects of the film were investigated.
