The present day environmental issues demand a lot from scientists and engineers
to keep the planet earth safe for its habitats. There were lot of attempts for
developing efficient air and liquid filters as the demand increases with an
utmost concern of present environmental situations. Thanks to its large surface
area to volume ratio, polymer nanofibers and composites are found to be good
substitute for conventional filters. As per the research and analysis data,
filtration efficiency increases proportional to the reduction of the average
diameter of the fibers. In this study, the most efficient electrospinning
technology was adopted to prepare polycarbonate (PC) nanofiber mat which yields a
very fine surface morphology. There are earlier researches and associated data
available about the preparation of PC nanofibers but with average fiber diameter
above 1000 nm. In this study, a systematic methodology was instigated to generate
PC nanofibers with least average diameter of 90 nm without using any surfactants
or salts. The most suitable solvents, solvent proportion, polymer concentration
and electrospinning conditions for the formation of the fiber mat are discussed
elaborately. PC fiber mat of least average diameter was proved to be highly
efficient for particulate matter adsorption using a dust sampling analyzer.
