As a very important kind of novel organic functional materials

micro- and nano-structured conducting polymers have become a hot research topic of organic material science field in recent years. This article mainly reviews the chemical and electrochemical methods for the controllable synthesis of conducting polymers with micro- and nano-structured morphology. The two synthesis methods are further divided into three main aspects: hard-template

soft-template

template-free self-assembly synthesis. In addition

the formation mechanism of conducting polymer micro- and nanostructures

obtained by these methods in previous publications

is discussed.
