Current research project was devoted to the development of the double layer composite membrane for efficient separation of carbon dioxide. Polydimethylsiloxane was used as a support layer and phthalic acid incorporated titanium dioxide as a selective layer. Developed membranes demonstrated unique gas separation performance with high selectivity separation of carbon dioxide and nitrogen.The mechanism of gases separation was attributed to the abundance of the carboxylic groups originated from the incorporated acids. The mechanism of material selectivity was verified using theoretical calculations (density functional theory). According to the calculations we have succeeded to create CO2-philic sites in the composite phthalic acid/titanium dioxide layer. These sites exhibit much higher attractive force for carbon dioxide gas compared to nitrogen. As a result we have in fact achieved the translation of the molecular level property (chemical affinity) to the material (high selectivity).
