Polyaniline, Interfacial polymerization, Layer-by-layer


The interfacial polymerization of aniline has been used to prepare water-soluble polyaniline. Polyaniline was made water-soluble by interfacial polymerization in the presence of poly(styrene sulfonated, sodium salt) (PSS), which acted as bundling agent to provide water solubility. The prepared polymer composite was later used for the fabrication of polyaniline nano-thin films using the layer-by-layer (LbL) self-assembly technique. Film produced by the LbL technique can be used in electro-chromic films, sensors or electro-catalytic films depending on the type of architectures. This paper first presents, a brief review on conducting polymer prepared by interfacial polymerization. Special interest is given to the synthesis of water-soluble polyaniline by interfacial polymerization in the presence of PSS. In a second part, the authors provide original results concerning the LbL self-assembly of polyaniline into nano-thin films. The PSS concentration used in the polyaniline synthesis is discussed regarding its effect on the growth of LbL composite thin films.
