morphological, color impact and spectroscopic studies of new schiff base derived from 1,2,4-triazole ring

This paper investigates the synthesis of novel schiff base having 1,2,4-triazole segment and its mixture with low concentrations of polystyrene to make a homogenous matrix. the edx (energy dispersive x-ray) technique have shown that the major component for both blank and blend polystyrene films is carbon atom. however, it has been demonstrated the appearance of new band related to oxygen, nitrogen, and sulfur for polystyrene/base blend film. this is because of the presence of schiff base within the polymeric film. the morphological images, after irradiation by uv light, for polystyrene (blank) film proved the formation of cotton-like fibrous material. micrographs showed the formation of crescent-like material after the irradiation of polystyrene-schiff base film by uv light for 300 h. this was due to the existence of polystyrene-schiff base with polystyrene which increased the photo stability of the polymeric film.
