Abstract Scope Recently, huge emissions of carbon dioxide have emerged as a major problem in different fields of engineering. Mixed matrix membranes are materials with huge potential for application in the field of carbon-dioxide removal from the flue gases. Preliminary experiments have shown that dense composite membrane with polyethyleneoxide (PEO) as a matrix and zeolite powder as a dispersed phase with appropriate additive that serves as a homogenizer can be used. This type of membranes has shown good permeability of carbon-dioxide and relatively low permeability for other gases (hydrogen, oxygen, nitrogen). The aim of this work is to test potential degradation of permeation properties and mechanical consistency of the membrane under repeated cycles of heating and cooling in presence of moisture. The experiments were performed at five different temperatures below melting or degradation point of polymers with three different partial pressures of water in combination with various gases.
