A Cold Plasma Generator and its Applications to Combinatorial Copolymerization of Carbon Dioxide with Organic Molecules

Summary: As an energy minimum process for CO 2 fixation, we propose the reaction of CO 2 with a hydrocarbon excited by our originally designed plasma reactor. In this reactor, the CO 2 /hydrocarbon ratio and pulsed plasma mode can be changed combinatorially to produce plasma copolymers under sequentially controlled conditions. The presence of CO double bonds in the FT‐IR spectra of the insoluble films confirmed that CO 2 has actually been incorporated into the plasma polymerized products.
