Abstract

Aims The simultaneous use of insulating polymers and nanostructures such as silver to produce triangular Nanocomposites, with the reinforcement of effect of each other, can have better results in improving the mechanical properties and processability of Age=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank">Polyaniline. The current study was conducted with the aim of preparation of Age=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank">Polyaniline/Age=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank">Polyvinyl Alcohol/Ag nanocomposite and characterization of its physicochemical and Antibacterial properties. Materials & Methods In the present experimental research, Age=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank">Polyaniline (PANI) was used as a conducting polymer, Age=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank">Polyvinyl Alcohol (PVA) was used as a biopolymer because of its biodegradable property. Ag nanoparticles also was considered as a reinforcing Agent of thermal stability, mechanical and Antibacterial property to prepare PANI-PVA-Ag nanocomposite. The synthesis of PANI-PVA composite and PANI-PVA-Ag nanocomposite was performed through Age=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank">Polyaniline and Ag addition in PVA solution. Different weight percent of components and Fourier-Transform Infrared Spectroscopy (FT-IR), Scanning Electron Microscopy (SEM), Thermogravimetric Analysis (TGA), and scanning electron microscope connected to the X-ray Diffraction System (EDX) were used to investigate the properties. Findings Thermal stability of the nanocomposite in comparison with pure PVA in temperatures above 400ᵒ C was promoted. The presence of PANI, PVA, and Ag in the FTIR spectroscopy showed the compatibility of the nanocomposite components. The greatest tensile strength belonged to PANI/PVA/Ag Nanocomposites with 88%, 9%, and 3%w/w. Conclusion The components of Age=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank">Polyaniline/Age=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank">Polyvinyl Alcohol/Ag are compatible. The presence of PANI and Ag nanoparticles in the structure of the nanocomposite improves its thermal stability than pure PVA at high temperatures. Age=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank">Polyaniline/Age=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank">Polyvinyl Alcohol/Ag canocomposite has inhibitory effect on gram-positive and gram-negative pathogenic bacteria. Reducing the weight percent of PVA or increasing the weight percent of PANI decrease the tensile strength.
