Characteristic of electrically conducting of polyaniline-coated latex particles

TL;DRAbstract

Electrically conducting polymers are insoluble in their doped, conducting state and hence suffer from poor process-ability. Latex particles of polyaniline have been synthesized in order to enhancing processability. Its stable colloidal suspensions have been used, such as to fabricated amperometric enzyme biosensor 3 , etc. In such applications as sensors, electronic devices or functional electrodes, the conductance is the key point. However, the conductance of polyaniline is strongly dependent on pH which hindered its application. Here, polyaniline-coated latexes were synthesized by the chemical polymerization of aniline on the polystyrene core or polystyrene-carboxyl core, etc. Electrically conducting redox-active particles were synthesized by coating nearmonodisperse, polystyrene (PANI-PS) or polystyrene-carboxyl (PANI-PSCOO) latex particles with polyaniline at 0 C. This low temperature synthesis route ensured that high quality polyaniline was produced. The particles had ‘core-shell’
