摘要: Abstract The permeation characteristics of poly (vinylidene fluoride) -poly (styrene sulfonic acid) interpolymer membranes in the separation polymers, (ethylene glycols), from their aqueous solutions were investigated under various conditions. influenced markedly by casting solution composition and operating temperature. It was seen scanning electron photomicrographs that changes ratio related to microporous structure resulting membranes. rates for glycols) greater than pure water. found this phenomenon dependent on physical chemical natures permeating molecules. mechanism through not only viscous flow.
