Polyacrylonitrile (PAN) has been used as fiber for improves particulate matter collection efficiency, be good stability and mechanical properties. Polar solvents is commonly used to solubilize PAN and dimethylformamide (DMF) and dimethyl sulfoxide (DMSO) are frequently used as solvents.

The aim of this work was to evaluate fiber diameter, pore area, superficial porosity and filtration performance of filter medias covered with fibers produced by Forcespinning (centrifugal spinning method) from PAN dissolved in DMF and DMSO...
