Elucidating the mixing effect of dual polymers via physical blending on its physicochemical, thermal and electrical properties for dye-sensitized solar cells

Blending two different polymers through a physical blending is a wise alternative to create a new polymer with desired properties showing a synergistic effect of the individual polymers. In this work, polyacrylonitrile (PAN) and poly (1-vinylpyrrolidone-co-vinyl acetate) P(VP-co-VAc) were blended in...
