Effects of PHZ and TiO2 on Image Properties of Silver Film Based on Photothermographic Materials

Abstract:

Article Preview

PTG materials were prepared using TiO2 as photoconductors, silver palmitate as a reducible silver salt, PHZ as a toner and 2246 as a reducing agent in acrylic acid resin binder. The PTG material was coated onto the PET film and then exposed by UV-meter. Effects of the amount of TiO2 and PHZ on the image properties were investigated by means of ultraviolet-visible spectroscopy (UV) and transmission density meter. The formation of silver image was confirmed from the absorption peak around 430nm and X-ray photoelectron spectroscopy (XPS) analysis. The results show that the optimum content is that PHZ of 0.5g and titanium dioxide of 0.03g. The Atomic Force Microscopy (AFM) showed that the triangle-like grains with size of 43nm and height of 10nm grew uniformly on the surface of the exposed PTG film.
