Uniform hydrophobic electrospun nanofibrous layer composed of polysulfone and sodium dodecyl sulfate for improved desalination performance

Recently, water reclamation and water reuse have received considerable attention because of high water demand. Membrane processes constitute the most convenient technology for water treatment and desalination. In this study, a novel class of enhanced performance membranes consisting of a highly hydr...
