Preparation of Miscellaneous Polyaniline Nanostructures

PANI nanoribbons, also known as nanobelts, have been synthesized by a self-assembly process using the chemical oxidative polymerization of aniline in a surfactant gel, formed by mixing an acetic acid solution of anihne and CTAB with an aqueous solution of APS 

The synthesis of spiral PANl nanostructures (2-D ordered spirals comprised of singlestrand PANI-NFs) by chemical oxidative polymerization using a hydrated surfactant sodium dodecylsulfonate crystallite template was recently described [406]. It was found that a spiral dislocation structure on the surface of a hydrated sodium dodecylsulfonate crystallite was responsible for the growth of the spiral PANl nanoarchitecture. It was revealed that APS has a strong tendency to induce the formation of a spiral dislocation stmcture in hydrated sodium dodecylsulfonate crystallites. A mechanism of adsorption of oligoanilines on the steps of dislocation has been proposed for the growth of PANl spirals.

Hollow PANI-NSs have been synthesized by the oxidative polymerization of aniline with APS in aqueous medium comprising poly(caprolactone)-PEO(1000)-poly(caprolac-tone) amphiphilic triblock copolymer micelles [419]. Hollow PANI-NSs were also
