Simplification of Template-free Method to Prepare Polyaniline Nanotubes

1 Introduction Conducting polymer nanostructures (e.g.nanotubes or nanofibers) have received considerable attention owing their unique properties and promising applications in technology and nano-devices[1]. Conducting polymer nanostructures can be generally synthesized through "hard" and "soft" template method.Usually an external hard template in a "hard-template" method is required and the post-treatment of removing template is rather tedious."Soft-template" method is advantageous of omitting external...
