羧基负离子型聚电解质与重氮树脂的自组装及自组装膜的光和热反应

带相反电荷的聚电解质的自组装，由于方法简单，对环境无污染，近年来备受重视［１～８］。以重氮树脂为聚正离子的聚电解质复合物，由于光照时重氮基分解，致使复合物的离子键转为共价键，溶解性发生重大改变，从而以重氮树脂为聚正离子的聚电解质复合物是一种新的光成像体系［９，１０］。张希等用重氮树脂与聚苯乙烯磺酸钠成功地制备了对极性溶剂稳定的自组装超薄膜［１１］。本文用羧基负离子聚电解质与重氮树脂进行自组装，并研究该自组装膜的光，热反应。羧基负离子聚电解质与重氮树脂的自组装超薄膜，文献上报道较少。１　聚丙烯酸钠…

THE SELF\|ASSEMBLY FILMS FROM DIAZORESIN AND CARBOXY\|CONTAINING POLYELECTROLYTES AND THEIR PHOTO\| AND THERMAL REACTIONS

The multilayer films from diazoresin (DR) and poly(sodium acrylate, PANa) or alkali hydrolytic maleic anhydride/styrene copolymer (PMSNa) were fabricated on mica. During the fabrication process the absorbance increases about 0\^033 for every fabrication cycle, indicating that the thickness of the film increases regularly. Under irradiation of UV light or heating, following the -N\-2\++ decomposition, the inoic bond of the film converts to covalent bond. The morphologies of the film after DMF etching for the different films (irradiatied or unirradiated etc) were observed by Atomic Force Microscopy (AFM) and the result shows that the ability of the film against etching from polar solvent increases obviously. The conversion of bond nature from ionic to covalent was verified preliminarily by FTIR spectral analysis.
