Effect of formation conditions of poly(ethylene-co-vinyl acetate) membrane on the membrane physical structure and pervaporation properties in the recovery of ethyl acetate from aqueous solution

Preparation and characterization of acrylonitrile–butadiene–styrene/poly(vinyl acetate) membrane for CO2 removal

“…Pervaporation of ethyl acetate from aqueous solution [11,12], methanol/MTBE [9], benzene/cyclohexane separation [13,14], and methyl substituted benzenes [10], are some of the major accomplished efforts.…”

Surface segregation of fluorinated moieties on poly(methyl methacrylate-ran-2-perfluorooctylethyl methacrylate) films during film formation: Entropic or enthalpic influences

“…The [g] value in the toluene solution was larger than that in cyclohexanone solution, especially for the copolymers with high FMA content. Since the chain conformation is most expanded in the best solvent, the intrinsic viscosity will be highest for the best match in solubility parameter according to the Mark-Houwink equation [34,63]. Therefore, we consider the polymer chain to be much looser and more expanded in the toluene solution.…”

“…From the result of dynamic light scattering (DLS), we did not obtain the information of Rh, it means the copolymer chains did not form the micelles in the toluene solution. The viscous flow energy (DE g ) is another important polymer property and can be determined according to the Arrhenius equation [63] ½g ¼ A expðDE g =RTÞ:…”

Gas permeability and permselectivity properties of ethylene vinyl acetate/sepiolite mixed matrix membranes

“…Over the last years, polymer/clay hybrids as mixed matrix membranes (MMMs) have drawn a great deal of attention for gas separation and gas barrier applications [1][2][3]. Up until now, two-dimensional (2D) clay minerals such as montmorillonite and its different derivatives have attracted the attention of the majority of researchers.…”
