Effect of humidity on the electrical properties of the silver-polyaniline/polyvinyl alcohol nanocomposites
Original language description
Polymer-metal nanocomposites with enhanced mechanical, optical, electrical, dielectric, and antimicrobial properties are currently in high demand for many industrial applications. Here, we study and present the effect of UV-reduced silver nanoparticles on the synthesis of polyaniline-polyvinyl alcohol-silver nanocomposites (PPVA-Ag) and utilize them to make a humidity sensor and antimicrobial agent. A thorough study of the surface morphology of the prepared films using SEM, AFM, and profilometry is performed; it is found that uniform film is formed in all these cases. These studies show that an increase in Ag concentration leads to an increase in the surface micro roughness of the PPVA-Ag film. XPS determines the chemical composition of the prepared PPVA-Ag nanocomposites. At different humidity conditions, the electrical resistivity of the PPVA-Ag nanocomposites is measured. The results show uniform changes in resistivity with an increase in humidity and good repeatability. These polymer-metal nanocomposites are found to have exhibited antimicrobial abilities making them useful for biomedical applications as well
