本研究工作以二甲基乙酰胺为溶剂,用均苯四甲酸二酐与4.4′-二胺基二苯醚进行反应,制备了具有一定粘度的聚酰胺酸树脂溶液.同时又以3,3′,4。4′-二苯甲酮四甲酸二酐、邻苯二甲酸酐、尿素,无水氯化铜等为原料,以钼酸铵为催化剂,经熔融缩合反应,制得含酞菁铜结构的二苯甲酮双酰亚胺;然后经水解反应,制备了含有酞菁铜结构的二苯甲酮四甲酸。将此含酞菁铜的羧酸衍生物溶于吡啶,然后再与所制备的聚酰胺酸树脂溶液混和均匀,用浸涂法或流涎法在某些底材上成膜,最后经酰亚胺化处理,便制得了含有酞菁铜结构的均苯型聚酰亚胺光导膜。试验表明。此种涂膜具有较好的光电导性。光照时,体积电阻率下降,导电性增加,光照1分钟后,导电性可增加10倍以上。本文研究了组成、光照时间、光波波长等对试样光电导性的影响;对合成产物的结构进行了初步的分析。取得了初步的研究结果。
In this work, dimethylacetamide was used as a solvent to prepare a polyamic acid resin solution with a certain viscosity by reacting pyromellitic dianhydride with 4,4’-diaminodiphenyl ether. At the same time, ’, 4,4’-benzophenonetetracarboxylic dianhydride, phthalic anhydride, urea, anhydrous copper chloride, etc. as raw materials, ammonium molybdate as a catalyst, by melt condensation reaction, to obtain phthalocyanine Copper structure of benzophenone bisimide; and then by hydrolysis reaction, prepared copper phthalocyanine structure containing benzophenone tetracarboxylic acid. This copper phthalocyanine containing carboxylic acid derivative was dissolved in pyridine, and then with the prepared polyamic acid resin solution mixed evenly, by dip coating or salivation method on some substrate film, and finally by imide Treatment, they have been prepared containing copper phthalocyanine structure of benzene-based polyimide light guide film. the experiment shows. This coating has good photoconductivity. Light, the volume resistivity decreased, increased conductivity, light 1 minute, the conductivity can be increased by 10 times. In this paper, the effects of composition, illumination time and light wavelength on the photoconductivity of the sample were studied. The structure of the synthesized product was preliminarily analyzed. Made preliminary research results.
