Development of poly(ethylene glycol) diacrylate membrane for facilitated CO2/N2 separation

Abstract Carbon dioxide (CO 2 ) is responsible for approximately 80% of greenhouse gases emission that the main source to global climate change causing notable environmental impacts. Poly (ethylene glycol) diacrylate (PEGDA) have polar PEG repeating units, which provide a strong affinity towards carbon molecules has been blended with 3-aminopropyltrimethoxysilane (APTMS) synthesize membrane CO /nitrogen (N separation. The new synthesized studied potential applications in gas separation and be implemented control emission. APTMS also used delay diffusion between polymer solvent. In this study, concentration PEGDA casting solvent terms mol ratio from range 0.9:1.1 1.3:0.7 discussed. Based on results, shows best performance at 1:1 where permeance both /N , selectivity are 75.21±0.15 GPU, 22.95±0.05 GPU 3.28±0.12, respectively. An optimal aminosilane/polymer reaction benefits due CO2 formation different surface morphology.
