Core/Shell-Structured PANI-Coated

PANI-Coated Core/Shell-Structured Nanocomposites... 

Different from the PANI-coated composite particle, microcapsules or core/shell-structured particles containing PANI with low pH or high conductivity as the core material are interesting because they do not need to additional dedoping treatment. 

Corrosion protection by ICPs has been well documented in several reviews [136-141]. The use of ICP-based core-shell latexes for the corrosion protection of steel is a relatively new field of research, and a recent review has proposed the exploitation of such possibihties [142]. In a recent study, we found that ICP-based core-shell latexes offer the possibility of achieving anticorrosion properties [143], though the presence of pinholes or scratches in the coatings enhances the corrosion rate of metals. This problem may be due to poor dispersion of the composite particles in the insulating resin systems, and future research will need to develop conductive polymer-based anticorrosive primers for metals. The anticorrosive properties of PANI-coated polystyrene latex microspheres has been reported recently [144]. PS-PANI composite particles with core-shell structure were prepared by chemical oxidative polymerization of anihne monomer in the presence of a PVP-stabilized PS latex suspension. The reduced form of the particle was obtained by adding hydrazine mono hydrate to the suspension. Both oxidized and reduced PANI-PS particles were used to obtain a PANI-PS-coated iron electrode (PANl-PS-Fe). Pure PANI...
