Structural, spectroscopic, cell viability, Anti-bacterial studies on PVC/PVDF doped by AgNPs via laser ablation for wound healing application

Abstract

Abstract Altering films structures to be utilized in wound healing applications is crucially needed to enhance quality of life. Different contributions of silver nanoparticles fabricated via laser ablation have been incorporated in (30% PVC/70% PVDF) blend. Changes in the structural, optical, and antibacterial property of the PVC/PVDF mixture prior to and after the incorporation of Ag were investigated using various techniques. FTIR shows vibrational spectral bands established a link between polymers and nanoparticles. XRD results approved the clear observation of the high concentration of silver nanoparticles in the last sample according to the peak at 38.42̊. UV-Visible analysis confirms the construction of AgNPs at 234 nm and the optical absorption edges were noticed for all of the obtained samples. SEM is employed to prove the generation of silver nanoparticles inside the solution utilizing laser ablation besides its dispersion in PVC/PVDF blend. The bacterial activity of AgNPs shows high activity index values at higher concentration of AgNPs. Blended PVC/PVDF/AgNPs could be suggested for wound healing applications. The values of the cell viability and antibacterial activity of the fabricated PVC/PVDF/AgNPs NPs films suggest these samples for utilization for biomedical applications as wound healing application.
