Carbon dioxide (CO 2 ) absorption process is a promising method in alleviating the environmental consequences of fossil fuel combustion, which is the primary cause of climate change. Membrane contactor as a well-developed, eco-friendly and waste-free technology is extensively used for gas separation. In this study, first attempt was made to prepare porous cyclic olefin polymer (COP) membrane for chemical absorption of CO2 using membrane contactor. The resultant membrane was characterized in terms of thickness (85 μm), porosity (80%), mean pore size (211 nm), water contact angle (111º), mechanical properties (tensile strength: 4.53 MPa, elongation at break: 4 – 8% and Young´s modulus: 208 MPa), and morphological characteristic. The CO2 absorption test that was performed at 27º C, showed the maximum CO 2 absorption flux (approximately 8.6 ×10 -5 mol/m2 .s) using 1M monoethanolamine (MEA) aqueous solution as absorbent. The effect of membrane orientaion was also studied.This study proposed the competitive and new membrane material for MC application.
