Abstract

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.

FT‐IR spectra of products copolymerized from a CO~2~/C~2~H~4~ system (a), and relative intensities of the carbonyl absorbance (b).
