Biocomposite films based on chitosan (Chit) and sodium alginate (Alg) and containing anti-inflammatory (zinc sulfate) and antimicrobial (sulfanilamide) pharmaceutical ingredients were prepared. The effects of variable chitosan and alginate contents on the chemical structure and phase transition temperatures of biocomposites were studied using infrared spectroscopy (FT-IR), nuclear magnetic resonance (NMR) and differential scanning calorimetry (DSC). Thermal analysis showed that the addition of pharmaceuticals decreased the melting temperature and melting enthalpy of polymer biocomposites.
