Abstract

A new-fangled polymer of poly(vinyl alcohol) (PVA) doped with various concentrations of lead(II) Titanate (PbTiO₃, PT) is prepared using the casting technique method. The prepared samples are identified by Attenuated Total Reflection- Fourier Transform Infrared (ATR-FTIR). The peaks characterized to PVA at 3280, 2917, 1690, 1425, 1324, 1081, 839 cm^-1 appeared, also the peak characterized to the presence of PbTiO₃ appeared at 713 cm^-1. The interaction between PVA and PbTiO₃ was confirmed by observing the change in IR absorption intensity. Optical properties were determined by Urbach theory and direct transition theory. The absorption edge values and the band tail energies decrease with increasing PbTiO₃. The values of direct and indirect band gaps decrease with increasing PbTiO₃ contents, indicating a variance in internal states by increasing PbTiO₃. Composite with 10 wt.% PbTiO₃ is promising for UV protective applications.
