摘　　要：采取选择性掺杂方法,将新型两亲性液晶嵌段共聚物薄膜功能化为具有各向异性的锂离子导电材料.这类薄膜不仅具有同轴且垂直取向的一维离子导电通道,而且可以在大面积范围内形成规则的阵列,可以作为锂离子电池、燃料电池等电化学能源系统的新型电解质.另一方面,这类薄膜作为模板可制备周期性排列的纳米孔、纳米粒子、纳米线阵列,形成的有序纳米结构材料可作为锂离子电池的三维电极.A new series of amphiphilie liquid crystalline block copolymer thin films, having normally aligned and highly ordered nanocylinder array, were functionalized as anisotropic ion conducting materials by selectively infiltration. These ion-active nanocylinders are coaxially aligned and hexagonally arranged in a large area, which might be used as novel types of electrolyte films for electrochemical energy systems such as lithium ion battery, fuel cell, etc. Since the ordered cylinders can carry on and store the ions, the block copolymer films can be utilized as the advanced template to fabricate the ordered array of nanoporous, nanoparticles, and nanowires for the potential application in lithium ion battery as three dimensional electrode materials.
