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 CO double bonds in the FT‐IR spectra of the insoluble films confirmed that CO 2 has actually been incorporated into the plasma polymerized products.FT‐IR spectra of products copolymerized from a CO 2 /C 2 H 4 system (a), and relative intensities of the carbonyl absorbance (b).
