| description | <p>Abstract</p> <p>There are many practical difficulties in direct adsorption of polymers onto nanocrystalline inorganic oxide surface such as Al<sub>2</sub>O<sub>3 </sub>and TiO<sub>2 </sub>mainly due to the insolubility of polymers in solvents or polymer agglomeration during adsorption process. As an alternative approach to the direct polymer adsorption, we propose surface-bound polymerization of pre-adsorbed monomers. 6-(3-Thienyl)hexanoic acid (THA) was used as a monomer for poly[3-(5-carboxypentyl)thiophene-2,5-diyl] (PTHA). PTHA-coated nanocrystalline TiO<sub>2</sub>/FTO glass electrodes were prepared by immersing THA-adsorbed electrodes in FeCl<sub>3 </sub>oxidant solution. Characterization by ultraviolet/visible/infrared spectroscopy and thermal analysis showed that the monolayer of regiorandom-structured PTHA was successfully formed from intermolecular bonding between neighbored THA surface-bound to TiO<sub>2</sub>. The anchoring functional groups (-COOH) of the surface-crawling PTHA were completely utilized for strong bonding to the surface of TiO<sub>2</sub>.</p> |
