Abstract

A new series of amphiphilic 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.
