浸润性梯度表面研究与应用被引量：2: 2012年; 浸润性梯度表面是指表面浸润性随着表面位置的变化而连续变化的一种特殊梯度表面.在过去的20年间,由于浸润性梯度表面在智能涂料、微流体器件和液体自输送等方面具有广阔的应用前景,因此人们研发并制备了各种类型的浸润性梯度表面,总体而言,可分为三类:(1)化学组成类浸润性梯度表面;(2)表面形貌类浸润性梯度表面;(3)化学组成-表面形貌复合型浸润性梯度表面.重点介绍了这三大类浸润性梯度表面的分类与区别,以及近些年来这些新型浸润性梯度表面的主要制备方法,如扩散法、浸泡法、刻蚀与打印、机械拉伸法、半月板沉积法和温度梯度法等,并归纳总结了这些方法的各自优缺点.在目前的材料科学领域,虽然关于浸润性梯度的研究还属婴儿期.可是利用梯度表面研究生物蛋白或细胞吸附,液体自输送等,已经发展成为一门成熟的学科.最后综述了近期关于浸润性梯度表面在研究生物蛋白或细胞吸附,液体自输送等方面的应用进展,并展望了该课题的未来发展.; 张继琳韩艳春; 关键词：浸润性接触角

双刚性共轭嵌段共聚物体系的自组装被引量：1: 2011年; 棒杆-棒杆(rod-rod)共轭嵌段共聚物体系是近几年发展起来的一类新型共轭聚合物材料,由于其特有的电学活性以及通过自组装实现纳米尺度结构可控等特性正逐渐成为人们研究的热点.构筑单元的刚性棒状结构使得rod-rod共轭嵌段共聚物体系倾向于自组装形成囊泡或层状结构等低曲率聚集体.本文总结了近年来关于rod-rod共轭嵌段共聚物体系自组装行为的研究,分别介绍了溶液中以及薄膜状态下双刚性共轭嵌段共聚物体系的自组装行为,在此基础上进一步讨论了rod-rod共轭嵌段共聚物薄膜结构与性能的关系.; 于新红韩艳春; 关键词：共轭嵌段共聚物自组装
