Abstract
A study on antibactericidal filter is carried out using electrospun polyacrylonitrile PAN nanofibres by incorporating different weight percentages of silver Ag nanoparticles Dimethylformamide DMF plays dual role as solvent for PAN and as reducing agent for the formation of Ag nanoparticles and the Ag nanoparticles were characterized using UVVisible Spectroscopy Xray diffraction and transmission electron microscopy Then PAN solutions with Ag nanoparticles were electrospun to produce nanofibres Areal density of nonwoven substrate electrospinning time and Ag were taken as independent variables to design the experiment for the preparation of filter BoxBehnken method has been used to derive the experimental plan and the filters were prepared according to the plan Later the developed filters were studied for bacterial filtration efficiency BFE as well as the antibactericidal activity against two commonly studied grampositive S aureus and gramnegative E coli bacteria From the study the developed Ag nanoparticle incorporated PAN electrospun nanofibre filters possess 99 BFE with good antibactericidal activity which enhances the potential application in protective mask
