Amphiphilic comb copolymers composed of poly(ethylene glycol) behenyl ether methacrylate (PEGBEM) and poly(oxyethylene methacrylate) (POEM) were synthesized via facile free radical polymerization. The structure of PEGBEM-g-POEM comb copolymer was confirmed by fourier transform infrared spectroscopy (FT-IR) spectroscopy, gel permeation chromatography (GPC) and nuclear magnetic resonance (1H NMR). Due to great solubility in ethanol, the PEGBEM-g-POEM comb copolymer could be directly coated onto the polysulfone supporting layer to prepare composite membranes. The maximum CO2/N2 selectivity of the PEGBEM-g-POEM membrane reached 84.7 together with a high CO2 permeance of 21.9 GPU (1 GPU = 10-6cm³(STP) / (s×cm²×cmHg).
