“…Thus, appropriate selection of polymeric material, which has superior separation performance and minimal solvent-induced swelling, is a crucial parameter. Generally, four modification approaches have been proposed to improve membrane stability and obtain high separation efficiencies, such as: (1) chemical cross-linking/grafting [2][3][4][5][6][7][8], blending [9,10], heat treatment [2,3,11,12], and the introduction of robust inorganic fillers [13][14][15].…”
