Effect of Silver Nano-Particles on Structural, Optical and Electrical Properties of Casted (Polyvinyl alcohol/ Polyacrylamide/Polyethylene oxide) Composites for Antibacterial Applications

The (PVA-PAAm-PEO) weight percentage blends with Ag nanoparticles as a nanocomposites (NCs) have been prepared by solution casting method. Optical microscope and SEM were used to investigated the diffusion of nanoparticles (NPs) in the blends. NPs agglomeration were clearly appears in the high weight additives. The materials have been diagnosed by optical microscopy, SEM and FTIR. The absorption spectrum records in the wavelength scope (190-1100) nm. The optical properties directly proportional with Ag nanoparticle additives except the transmittance and the energy gap were decreased. The optical parameters show that Ag doping clearly effects on the films characteristics, the optical constants enhanced. The AC electrical conductivity also calculated. This results can be applied in coatings for photographic films. The results applied as anti-bacterial to E-coli bacteria with the used additives of Ag (20-30 nm) NPs. The antibacterial effect of the prepared films also tested to be accompaniment with other applications.
