The present work focuses on the synthesis and application of nanocomposites Montmorillonite-Poly-vinyl Acetate Acrylate (MMT-PVA) in CO2 adsorption field. Firstly the montmorillonite was modified by simple cation exchange with Na+, the obtained material was used as charge for polyvinyl alcohol and were characterized using various techniques such as X-ray Diffraction (XRD), Fourier transform infrared spectroscopy, Thermogravimetric Analysis (TGA) and Differential Scanning Calorimetry (DSC). The results show that the nanocomposites is obtained by the intercalation of the MMT, increasing the content of MMT leads to the increase of the interlayer distance, CO2 adsorption at 0°C was carried using a volumetric method, and the recorded isotherm indicated that the CO2 adsorption capacity of MMT-PVA can be enhanced through modification by PVA. The Na-MMT has low CO2 adsorption capacity compared to that Nanocomposite.
