Thermal degradation properties of solid polymer electrolyte (poly(vinyl alcohol)+phosphoric acid)/methylene blue composites
TL;DR: The thermal stability and degradation of poly(vinyl alcohol) (PVA), PVA+H 3 PO 4 (solid polymer electrolyte, SPE), pVA containing methylene blue (MB) dye and SPE+MB were studied by TG/DTA/DTG and DSC techniques as discussed by the authors.

Synthesis and characterization of polyaniline dispersions
TL;DR: In this article, the PANI dispersions were deposited in the form of the film on indium-tin-oxide (ITO) coated glass by dip-coating and the morphology of these PANIs have been studied by scanning electron micrograph (SEM), optical absorption by UV-VIS spectroscopy and the cyclic voltammetry properties of these films in non-aqueous electrolyte (0.01m HCl/acetonitrile) and the interesting results are reported in this communication.
