“…Polyvinyl alcohol, however, has been extensively used by various researchers for making a wide variety of composites as it exhibits unique properties like solubility in water, good film-forming character, suitable physical properties, high hydrophilicity, processability, non-toxicity, biocompatibility, bio-degradability, chemical resistance, and availability with different molecular weights [16][17][18]. The nanofillers such as metal salts and oxides, pure metals, clays, double hydroxides, etc., have been reported to make composites [11][12][13][14][15][17][18][19][20][21][22][23].…”
