ECO-FRIENDLY CONDUCTIVE NANOCOMPOSITE BASED ON POLYPYRROLE: PREPARATION AND INVESTIGATION OF BIOLOGICAL ACTIVITES

Eco-friendly polypyrrole@dextrin (PPy@Dex) nanocomposites were prepared by in-situ polymerization of pyrrole in dextrin suspension using ammonium peroxydisulfate as an oxidant. Both Fourier transform infrared (FTIR) and X-ray diffraction confirmed that the successful formation of PPy@Dex nanocomposite. Field emission scanning electron microscopy (FESEM) observation revealed the fine grain nanostructure of the PPy on the nanocomposites with average grain sizes in the range of 80–150 nm. The conductivity of nanocomposites was investigated by four probe technique. The biological properties of prepared nanocomposites such as, biodegradability, antioxidant and antibacterial activity were evaluated. The results illustrated that with increasing of pyrrole feed ratio in nanocomposite electrical conductivity, antioxidant and antibacterial activity increasing and biodegradability decreasing
