Poly(3,4-propylenedioxy-2,2':5',2"-terthiophene)/TiO2 and poly(3,4-(2,2-dimethylenepropylenedioxy)-2,2':5',2"-terthiophene)/TiO2 nanocomposites were synthesized by a simple solid-state method. Additionally, the poly(3,4-propylenedioxy thiophene)/TiO2 and poly(3,4-2,2-dimethylenepropylenedioxythiophene)/TiO2 nanocomposites were synthesized in a similar manner for comparison. The structure and morphology were characterized by Fourier transform infrared (FTIR), ultraviolet-visible (UV-Vis) absorption spectroscopy, X-ray diffraction (XRD) and transmission electron microscopy (TEM). The photocatalytic activities of the nanocomposites were examined through the degradation processes of a methylene blue (MB) solution under UV light and sunlight irradiation. The results of FTIR and UV-Vis spectra showed that the composites were successfully synthesized by solid-state method and the poly(3,4-propylenedioxy-2,2':5',2"-terthiophene)/TiO2 and poly(3,4-(2,2-dimethylenepropylenedioxy)-2,2':5',2"-terthiophene)/TiO2 nanocomposite had a higher oxidation degree and conjugation length than others. The results also indicated that the TiO2 had no effect on the crystallinity of composites, but was well embedded in the polymer matrix. Additionally, the highest degradation efficiency of 90.5% occurred in the case of the poly(3,4-propylenedioxy-2,2':5',2"-terthiophene)/TiO2 nanocomposite. View Full-Text
