초록
Mesoporous titanium dioxide (TiO_2) thin films were prepared using poly(vinyl chloride)-graft-poly(N-vinyl pyrrolidone) (PVC-g-PVP) as a templating agent via sol-gel process. Grafting of PVC chains from PVC backbone was done by atom transfer radical polymerization (ATRP)technique. The successful grafting of PVP to synthesize PVC-g-PVP was checked by fourier-transform infrared spectroscopy (FT-IR) and gel permeation chromatography (GPC). The carbonyl group interaction of PVC-g-PVP graft copolymer with TiO_2 was confirmed by FT-IR. The porous morphologies of the TiO2 films genereated after calcination at 450oC was characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The mesoporous TiO2films with 580 nm in thickness were used as a photoelectrode for solid state dye sensitized solar cell (DSSC) and showed an energy conversion efficiency of 1.05% at 100 mW/cm^2.
