This work demonstrated an in-depth investigation of the effect of surface doping by three different polymers on the synthesis of zinc ferrite nanostructures by a thermal method. The zinc ferrites were doped with 20% concentration by mass of Polyvinyl alcohol (PVA), polyvinylpyrrolidone (PVP) and ...
