Interfacial polymerization nanostructured polyanilines

Cyclic nanostructured polyanilines (Figure 2.23) have been synthesized by means of a simple modified aqueous/organic interfacial polymerization with the aid of PAA [405]. The cyclic PANl nanostructures were formed by severe secondary overgrowth through the electrostatic interaction between anihne/oligoaniline and PAA chains. The average diameter of the obtained cychc structure was ca. 400 nm and its conductivity was 1 S cm . ...

There are various methods to synthesize polymer nanostructures, i.e., template synthesis, chiral reactions, self-assembly, interfacial polymerization and electrospinning. Recent developments in conducting polymer nanotubes and nanofibers were summarized by Long et al. Different preparation methods, physical properties, and potential applications of one-dimensional nanostructures of conjugated polyaniline (PANI), pol5 3nrole (PPy) and poly (3, 4-ethylenediox3d hiophene) (PEDOT) were discussed.
