The photocatalytic characteristics of titanium dioxide (TiO2) nanoparticles facilitate the functionalization of coating material for photo-catalysis substrate. We report on the development of a new photoactive material via TiO2 modified 2-chloro-3',4'-dihydroxyacetophenone (CCDP) quaternized poly(ethylene glycol)-g-[poly(dimethyl amino methacrylate)] [PEG-q-CCDP]. This system can also assemble with single wall carbon nanotube (SWCNT) or various substrate owing to excess catechol contents functionalized polymer [PEG-q-CCDP]. Varying deposition of TiO2 and TiO2 with substrate has demonstrated the photocatalysis effect in response to UV and visible light, respectively. The morphology and robustness of TiO2/PEG-q-CCDP and TiO2/PEG-q-CCDP with substrate was verified by contact angle, XPS, raman spectra, and SEM measurements. The concept proved in this work is transferable to a wide range of other inorganic compounds on versatile coated substrates. |
