摘要
Poly ortho aminophenol (POAP)/nanocrystalline TiO2 composite were electrodeposited from through cyclic voltammetry scans to afford conductive polymer/TiO2 nanocomposite. Polymerization of ortho aminophenol (OAP) proceeded after ultrasonic irradiation of nanocrystalline TiO2. The aggregation of nano TiO2 can be reduced under ultrasonic irradiation, and the nanoparticles can be redispersed in the aqueous solution. The presence of nanocrystalline TiO2 strengthens the UV absorption of POAP and leads to a blue shift of the pi-polaron absorption of POAP. Experimental absorbance spectra of TiO2/conductive polymer nanocomposite compared with results that obtained from the Maxwell-Garnett theory (MGT). (c) 2013 Elsevier B.V. All rights reserved.
