Abstract

CHITOSAN (Chito) as a biopolymer with high ANTIBACTERIAL, biocompatibility and biodegradability and POLYANILINE (PANI) as a conductive polymer and silver (Ag) nanoparticles to enhance ANTIBACTERIAL property were used to preparepolyanilin-CHITOSAN-silver (PANI-Chito-Ag) NANOCOMPOSITES. The synthesis of PANIChito composite and PANI-Chito-Ag nanocomposite was performed through anilinepolymerization in the presence of Chito and Ag. In order to evaluate the physicochemicaland ANTIBACTERIAL properties of synthesized composite and NANOCOMPOSITES, severalcombinations of components with different weight ratios were used. ANTIBACTERIALtests were performed using two different types of bacteria: Escherichia coli (gramnegative bacteria) and Staphylococcus aureus (gram-positive bacteria) to determinethe ANTIBACTERIAL capability of the PANI-Chito-Ag nanocomposite. The obtained results showed that higher Chito and silver contents produced stronger ANTIBACTERIAL property.The biodegradability test results confirmed that, the biodegradability increased as the content of Chito increased. Also, by increasing Streptomyces (gram-positivebacteria) concentration in natural soil, the biodegradability rate of nanocompositewas enhanced. The results obtained from thermogravimetric analysis (TGA) testsalso indicated improvement in thermal stability of PANI-Chito-Ag nanocompositecompared to that of pure Chito. Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy(EDX) were used to analyze and characterize the composition and structure of PANIChito-Ag triple hybrid nanocomposite. The results confirmed uniform distribution of Ag nanoparticles within the polymer matrix.
