Abstract

A conducting polymer composite, poly (3-octylthiophene)/titanium dioxide nano-composite was first synthesized through the ultrasonic method. The results from X-ray diffraction, X-ray photoelectron spectroscopy and infrared spectroscopy show that there is chemical interaction in the composite, which indicates that TiO2 was successfully coated by poly (3-octylthiophene) molecules. The energy gap of the poly (3-octylthiophene)/titanium dioxide composite is lower to 0.65 eV; and it also shows that the optical performance of the new material is far superior than POT or TiO2 separately, by Ultraviolet–visible spectra and fluorescence spectroscopy.
