凹凸棒石/炭对低浓度亚甲基蓝的吸附性能
吴雪平 1, , 徐艳青 2, , 张先龙 反应性液晶通过光聚合反应与聚芳醚光取向膜复合方法,制备了平面转换(In-plane switching,IPS)液晶显示器件,并在高温状态下对其光电显示和取向稳定性能进行了研究。结果显示,与单一聚芳醚光取向膜相比,利用复合光取向膜制备的 IPS 器件在高温状态下的光电显示和液晶取向稳定性能都得到了明显提高,在65℃明亮显示20 h 无液晶取向变化,在120℃维持2 h 无明显光量渗透。在线偏振紫外光下,光敏聚芳醚薄膜发生各向异性光交联反应,其交联程度最高可达67．4％。SEM 分析结果发现,反应性液晶单体在 UV 光照射下,在聚芳醚光取向膜表面上发生了各向异性光聚合反应,沿先前光取向方向形成长度为0．4μm 左右的棒状聚合物,有效限制了光取向膜中未交联的柔性基团的活动能力,进而有效增强了复合取向膜对液晶的取向稳定性。","authors":[{"authorName":"铁伟伟","id":"e03e9858-78cf-4fd2-ba1f-ae949ad275ef","originalAuthorName":"铁伟伟"},{"authorName":"张艳鸽","id":"2a1bc2b4-1e39-4210-a0dc-83f11418369b","originalAuthorName":"张艳鸽"},{"authorName":"郑直","id":"d835bc71-651b-4a41-b716-2381725555ad","originalAuthorName":"郑直"},{"authorName":"李升熙","id":"2703d2b6-8c83-42d3-898a-853abfae2344","originalAuthorName":"李升熙"},{"authorName":"李香丹","id":"b6b861c8-99a9-4145-9c8f-5c35b4eaf127","originalAuthorName":"李香丹"}],"doi":"10.3788/YJYXS20153005.0763","fpage":"763","id":"02eb5c01-46f1-40ed-8a91-250524450652","issue":"5","journal":{"abbrevTitle":"YJYXS","coverImgSrc":"journal/img/cover/YJYXS.jpg","id":"72","issnPpub":"1007-2780","publisherId":"YJYXS","title":"液晶与显示
