Abstract
The polyaniline (PANI) coated titania (TiO2) have been prepared with ammonium persulfate (APS) as an oxidant in sodium dodecylsulfate(SDS) micellar aqueous solution. These nanosized powders could transfer into the organic phase. With increase in the amount of SDS, the dispersibility into the organic solvent was increased. The obtained composites showed 14S/cm of conductivity at maximum while the value was about same on the polyaniline coating ratio in range of 100~20wt%. The conductivity value of composite with 20wt% polyaniline was about 10,000 times higher than that of raw titania. These modified titania had properties of polyaniline and titania together. The detailed structure and property analyses with X-ray, UV-spectroscopy, electron microscopy and so on will be discussed in relation to the synthetic conditions.
