Interfacial Polymerization Controlled Morphology Polyaniline And Properties

In order to obtain the nanometer polyaniline materials with controlledmorphology， the interfacial polymerization was used to prepared polyanilinenanotubes, fiber and ball. The properties were investigated and their structure,properties were characterizedIn detail, deionized water and carbon tetrachloride (CCl4) were used as inorganicphase and organic phase respectively, by changing the ratio of organic phase/inorganic phase, the size and performance of product were controlled. The resultsshowed that we obtained the polyaniline nanotubes, its diameter and aperture wereslightly increased as the increasing of organic phase/inorganic phase. Methylenechloride and toluene were also used as organic to prepared polyaniline nanotubes andnano-rod respectively, the morphology changed. The conductivity of product preparedby this method is not high and it can be increased two orders of magnitude bysecondary doping HCl.Polyaniline microsphere was synthesized with sodium dodecyl sulfate (SDS) andCCl4as inorganic phase and organic phase. Compared former, the structure of producthad slightly variation, the conductivity increased to a high level, morphology changedgreatly.Polyaniline nanofiber was synthesized with HCl and CCl4as inorganic phase andorganic phase respectively. The results showed that with the increasing of theconcentration of HCl, the morphology of the product changed from nanofiber intonanoparticles, while the conductivity increased.According to the morphology of PANI, the three system formation mechanismwas made a brief analysis and the experimental phenomenon was reasonableexplanation. Meanwhile three kinds of product conductivity and electrochemicalactivity were compared; results showed that electrochemical activity of HCl dopingwas the highest. The electrochemical activity of second doping product also hadgreatly improved.
