摘要 用聚合物的后重氮偶合方法合成了以可溶性聚酰亚胺为主链 ,偶氮生色团为侧基的新型偶氮高分子 ,并通过引入线性长链烷烃侧基来提高聚合物的溶解性 .采用红外光谱、氢核磁共振、紫外光谱和热分析等手段 ,对产物的结构、热性能及光学性能等进行了表征 .该聚合物膜在氩离子干涉激光的照射下形成正弦波形的表面起伏光栅 ,起伏深度可达 2 0 0nm . A novel soluble azo polyimide has been prepared from a post azo coupling reaction scheme.The polyimide based precursor polymer was obtained from the polycondensation of N,N bis[(3,4 dicarboxypheny anhydride) 1 carboxyethyl]aniline and 4,4′ diamino 4″ hexadecyloxtriphenylmethane.It is soluble in polar organic solvents such as tetrahydrofuran(THF) and N,N dimethylacetamide (DMAc).The azo polymer was synthesized by the reaction of the polyimide based precursor polymer and diazonium salt.Both the precursor polymer and the azo polymer were characterized by 1H NMR,DSC,FTIR and UV Vis spectrometry.The effect of long alkyl side chain on the enhancement of solubility was confirmed.When the spin coated azo polymer film was exposed to an interference pattern of Ar + laser,regularly spaced sinusoidal surface relief grating (SRG) was formed with depths up to 200 nm.The diffraction efficiency of the detecting laser was recorded to monitor the forming process of SRG and the surface structure on the film was also observed directly by using an atomic force microscope.The result shows that the soluble azo polyimide with surface relief grating forming ability has been successfully synthesized.
