Optical Properties of Poly (Vinyl Chloride-co-Vinyl Acetate-co-2-Hydroxypropyl Acrylate) / (Acrylonitrile-Butadiene-Styrene) Blends
The morphology and optical properties of PVVH, ABS and its polyblend samples have been studied using different techniques such as atomic force microscopy, AFM, Fourier transform-Infrared, FTIR, Raman spectroscopy and UV-Vis spectroscopy. AFM images showed that roughness of polyblend samples is increased as PVVH content is decreased in the polyblend samples. FTIR spectroscopy has been investigated for PVVH, ABS and its polyblend samples in the range from 4000 to 500 cm-1. The characteristic absorption bands of PVVH and ABS are detected. On the other hand, the main absorption bands of pure materilas have been affected in their positions and intensities in the FTIR spectra of polyblend samples. Raman Spectroscopy is carrid out for all the samples in the range 3650-50 cm-1. Analysis of UV spectroscopy showed that absorption edge and indirect optical energy gap are decreased with decreasing PVVH content in polyblend samples
