Application of poly(ethylene terephthalate)-graft-polystyrene membranes in pervaporation

Gamma radiation-induced grafting of styrene (ST) onto poly(ethylene terephthalate) (PET) films was used to prepare poly(ethylene terephtalate)/polystyrene (PET-g-PST) membranes having various degrees of grafting. Various characterization techniques were used to study both surface and bulk properties...
