| 摘 要： | 利用银镜反应在玻璃基底上制备了粗糙银膜，组装烷基硫醇后得到超疏水银膜.研究了［Emim］［BF4］、［Bmim］［BF4］、［Hmim］［BF4］、［Hmim］［Br］和［Hmim］［OTf］等一系列离子液体和不同浓度KCl水溶液在超疏水银膜表面的电润湿性能，分析了离子液体中离子体积、离子液体液滴大小，以及超疏水表面组装层的分子结构对其电润湿性能的影响.结果表明，离子液体的电润湿性能与离子体积和电荷偏离有关，与液滴体积无关，相似电导率的离子液体与KCl水溶液具有相似的电润湿性.

| Abstract: | Rough silver films were fabricated on glass substrates using silver mirror reaction,and the superhydrophobic surface was obtained by subsequent self-assembly with alkyl thiol.Electrowetting properties of various ionic liquids,including ,,,,and ,and aqueous KCl solution with different concentations on these superhydrophobic silver films was investigated,and the influence of factors such as the ion volume,the size of liquid droplet and the molecular structure of assembled layer on the electrowettablity was di... |
