摘要
采用氨基蒽醌与聚异丁马来酸酐进行缩合反应,制备了2种以氨基蒽醌为锚固基团、以聚异丁烯为助溶基团的电润湿显示非极性油墨材料的分散剂.该类新型分散剂的锚固基团为蒽醌环,与蒽醌类有机颜料的结构高度相似,因此该锚固基团与分散颜料之间具有良好的吸附作用;同时,拥有22个碳原子的聚异丁烯长链基团在电润湿油墨介质中具有超高的溶解性,其较大的分子量提供的空间立体保护作用提高了分散油墨体系的溶解度和稳定性.以分散红-FB为着色剂,调节分散剂和分散红-FB的质量比(1∶1、1∶2、1∶3),通过机械研磨法,得到吸光度增强的电润湿显示分散油墨材料.该分散型油墨材料的平均粒径达267 nm.器件应用测试结果表明:该分散型油墨材料具有良好的器件响应性能.
With condensation reaction of amino-anthraquinone and polyisobutyl maleic anhydride,two kinds of dispersing agents are prepared for electrophoretic non-polar ink materials with amino-anthraquinone as anchoring group and polyisobutylene as cosolvent group.The anchoring group of the novel dispersant is an anthracene ring,which has a high structural similarity with an anthraquinone-based organic pigment,so the anchoring group has a good adsorption force with the dispersed pigment;meanwhile,it has 22 carbon atoms.The polyisobutylene long-chain group is a ultra-solubilizing group in the electrowetting ink system,and its large molecular weight provides spatial stereo protection for improving the solubility and stability of the dispersed ink system.,and is prepared.With the mechanical grinding method,the electrowetting display dispersing ink material with higher absorbance is obtained with the dispersing red-FB as a pigment and with the 1∶1,1∶2 and 1∶3 mass ratios of the dispersing agent and the dispersed red-FB.The average particle size is 267 nm.The device application test shows that the dispersed ink material has good device response performance.
