In recent decades, studies sponsored by government and non-government agencies have warned at global level, the deleterious consequences of rising carbon dioxide (CO2) emissions arising from the burning of fossil fuels. In the Brazilian context, the economic stability of recent years has led to a significant increase in the fleet of motor vehicles, contributing directly to noticeable changes in the environment, especially in large cities.Among the strategies for post-combustion CO2 capture, the use of polymeric membranes has gained prominence opposite to conventional technologies adopted currently. Among the advantages, it is cited ease of preparation, assembly and low cost.Ionic liquids have high sorption capacity of CO2, which has led to the development of CO2 capture systems based on ionic liquids supported on polymeric membranes. However, there is little information available about changes in the internal structure of polymer matrices for transport of CO2 by the presence of ionic liquids. In addition, there are few investigations on the effects of processing history of these membranes on CO2 transport properties and interactions between the ionic liquid and the polymer matrix.In this scientific proposal, membranes based on poly(etherimide) containing imidazolic-based ionic liquid will be submitted to different thermal treatments in order to analyze the correlation structure x transport property of CO2 x thermal treatment.
