Despite the fact that more than 40 years have passed since the discovery of intrinsically conducting polymers (ICPs), one can see still growing interest in high-tech materials and devices on their basis due to their unique complex of physical and chemical properties [1]. Among these materials nanocomposites of ICPs with common polymers hold great potential as typically reveal synergetic properties. One of the most effective approaches to produce such nanocomposites is chemical oxidative polymerization of a corresponding monomer in a presence of nanoparticles of a common polymer. Our work is aimed at synthesis and investigation of core-shell nanocomposites polystyrene (PS) with one of the most important ICP representatives poly(3,4-ethylenedioxythiophene) (PEDOT) doped by different anions (toluenesulfonate, dodecylbenzenesulfonate, laurylsulfate, sulfate, chloride). First, the latex containing 30 nm PS nanoparticles stabilized with sodium dodecyl sulfate was prepared by miniemulsion polymerization of styrene in water media. At the next stage, the PS/PEDOT nanocomposites were synthesized by chemical oxidative polymerization of EDOT monomer in the PS latex media. The composition and properties of the nanocomposites were studied by UV-Vis and FTIR spectroscopy, TEM, thermogravimetry. It was found that these nanocomposites are conductive and have high thermal stability that suggests their applications as antistatic and sensor materials.
