CO2 polymer captures greenhouse gases

A new porous organic polymer has been found to be an effective material for capturing carbon dioxide according to Chemical and Engineering News. The CO2 capturing polymer was made by introducing tetrazole groups into a microporous polymeric framework. Potential applications for the new polymer include the capture and or storage of CO2.

Similarly, United States Patent 7,776,137 to Sudhir Kulkarni of Wilmington Delaware teaches a mixed matrix polymeric composite capable of capturing carbon dioxide. The CO2 capturing polymer mixed matrix composite may take the form of a hollow fiber membrane that serves as the separation media. The CO2 capture patent was assigned to Air Liquide of Paris, France. The basic polymeric unit of the invention is:
