Abstract EN
Polysulfone/polyethylene glycol (PSF/PEG) membranes were prepared by dry/wet phase inversion method.
Effects of direct current glow discharge plasma using argon as working gas on morphological structures and gas separation properties of membranes were studied.
Alteration of membrane characteristics were analyzed by various techniques like contact angle, scanning electron microscope, Fourier transform infrared spectroscopy, and dynamic mechanical thermal analysis.
Gas separation properties were measured in terms of permeation and ideal O2/N2 selectivity.
Results showed that hydrophilic and gas separation properties of PSF/PEG membranes increased by plasma surface modification.
It was also shown that the dosage of PEG and plasma treatment affected the morphological structures and mechanical and gas separation properties.
The macro voids and transmembrane structure disappeared with a little amount of PEG dosage.
Pore size and mechanical strength tend to decrease with increasing PEG dosage up to 10 wt%.
Glass transition temperature (Tg) receded from 201.8 to 143.7°C for pure PSF and PSF/PEG with PEG dosage of 10 wt%.
O2 and N2 gases permeation through the 10-minute plasma treated membranes tend to increase.
However, the permeation strongly dispersed when treatment time was more extended.
