Novel Fabrication Method for Hexagonal Plate-like Polypyrrole Nanostructures with High Electrical Conductivity and Excellent Thermal Stability

摘要

In the past several years, there has been increasing interest in conducting polymer nanostructures because of their unique properties and various applications such as chemical sensor, biosensor, electronic device, mechanical device, drug delivery, storage, bioencapsulation, supercapacitor, and substitute for carbon nanotub, etc. [1,2] These conducting polymer nanostructures can be categorized into 1- dimensional nanostructures such as nanofibers and nanotubes, 2- dimensional nanostructures such as micro or nanoplate and 3- dimensional structures such as core-shell nanostructures and nanospheres. There are three common routes to synthesize or fabricate these conducting polymer nanostructures; one is hard template method [3], second is soft template method [4] and final method is template-free method. [5] One of the recent fundamental issues in conducting polymer nanostructures is focusing on modifying former methods and developing new methods. [6] However, efficient regulation of the morphology and the size for conducting polymer nanostructures remains still weak. Therefore, a more effective and simple preparation method is necessary as an object of scientific research.
