DBS investigation on films of cobalt chloride doped PVA-PVP blend
[摘要] Films of Cobalt Chloride (CoCl2) doped polyvinylalcohol(PVA)-polyvinylpyrrolidone(PVP) blend (doped from 0.5 wt% up to 28 wt%) were prepared by solution casting, and characterized by XRD, DSC, UV-Visible Spectrometry TGA, FTIR and electrical measurements. In this paper, the results of Doppler Broadening Spectroscopy (DBS) in CoCl2doped PVA-PVP blend is discussed. An increase in crystallinity of PVA-PVP blend, is observed, on doping it with CoCl2. The DBS results are complemented by XRD and DSC scans.
