文摘

Poly(o-anisidine) (POA)/TiOb>2b> composite microspheres were synthesized in the presence of salicylic acid (SA) as a dopant with ammonium persulfate as an oxidant. POA-SA/TiOb>2b> composites thus obtained exhibited regular spherical morphology. Hydrogen bonding between the OH group of SA and the amine group of polymer chain was considered to be the driving force for the self-assembly of microspheres. Spectral studies and XRD indicated the presence of interactions between poly(o-anisidine) macromolecules and TiOb>2b> particles. Conductivity of 8.72 ¡Á 10^?#xA0;4 S cm^?#xA0;1 was obtained for POA-SA/TiOb>2b> composite microspheres containing 24.5 % POA. These composite microspheres can potentially be used in commercial applications as fillers for antistatic and anticorrosion coatings.
