ABSTRACT

By esterifying polyvinyl alcohol and gelatin, a blend hydro gel was attempted to be prepared in the current experiment. The traditional solution-casting technique was used to further transform the blended hydro gel into films. FTIR, X-ray diffraction, SEM, TGA analyses were used to analyses these films. Pf swelling test, MVTR and WVTR behavior of films were also studied. The free carboxylic group of gelatins had been completely esterified, according to the FTIR spectra of the polymer mix film. The TGA results that indicate melting point of polymeric films at different higher temperatures this way other analysis like SEM and XRD also shows the properties of the film. Gelatin and PVA interact to alter the crystallite's properties and degree of crystallinity. Gelatin was primarily responsible for the blend film's crystallinity. The segment density within the molecular coil increased, according to the viscosity comparison. The findings demonstrated the modifications in the gel's characteristics and improved gel formation during the material's viscoelastic phase. The mix film was strong enough and capable of holding water. Keywords: PVA, Gelatin, FTIR, TGA, XRD, SEM, PF swelling
