Design of pervaporation membrane for organic-liquid separation based on solubility control by plasma-graft filling polymerization technique

In Separation and Purification

“…Pore -fi lling membranes composed of porous PE or PP fi lled with grafted poly(MMA) prepared by plasma copolymerization have found their application in pervaporation separation of the benzene/cyclohexane mixture [169,172] . The membranes showed high permselectivity for benzene.…”

Electron beam radiation graft modification of preformed polymer architecture

“…By grafting a polymer film or membrane the solubility of various species can be increased in this polymer material. There are several examples where plasma graft polymerization has been used for the preparation of pervaporation membranes [30][31][32]. The principles of improved separation based on solubility control in graft copolymers described in these references can be applied to separations as well as pervaporations and the graft modification can also be performed by EB grafting.…”

Sorption and pervaporation properties of crosslinked membranes of poly(ethylene oxide imide) segmented copolymer to aromatic/nonaromatic hydrocarbon mixtures

“…[1][2][3][4] For application of membranes to PV process of aromatic/nonaromatic hydrocarbons, many investigators have been working on developing aromatic-permselective membranes with high performance. [5][6][7][8][9][10][11][12][13][14][15][16] Good PV membranes should have high selectivity, permeation flux, stability, and low cost. PV selectivity is mainly due to the solubility selectivity because the diffusivity selectivity is considered to be low or negative, judging from the molecular size of the penetrants.…”
