dc.description.abstractA unique biodegradable terpolymer composite with polyaniline and graphene oxide were developed using grafting methyl methacrylate, 2-ethylhexyl acrylate, ethyl acrylate and acrylonitrile as gelatin backbone with aid of an initiator ammonium persulfate (APS). Free radical polymerization was used for the development the terpolymer and its composites. The synthesized polymeric composites show outstanding antioxidant activity against ABTS and DPPH, with DPPH activity being greater than ABTS, as indicated by the low IC50 value (IC50 = 0.23 against DPPH and against ABTS IC50 = 0.94, respectively, was lower than that of ascorbic acid IC50. Over the course of three months, the degradation investigation showed that the weight loss for the terpolymer and composite was 7.20%, 7.15%, 16.50% and 15.01%, respectively. As determined by the soil burial method, the original weight of the terpolymer and its composite greater than before as a result of water adsorption and then decreased. Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC) were used to analyze the synthesized terpolymer and its composites. The FTIR spectrum of terpolymer shows strong bands at 2252 cm−1, 1723 cm−1, 1707 cm−1, 1146 cm−1, which attest to the monomer grafting with gelatin backbone. The TGA analysis shows that there’s a rapid decrease in weight is seen till around 450 °C and not completely destroyed till 600 oC.
