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

Abstract

AbstractSummary: As an energy minimum process for CO2 fixation, we propose the reaction of CO2 with a hydrocarbon excited by our originally designed plasma reactor. In this reactor, the CO2/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 CO2 has actually been incorporated into the plasma polymerized products.FT‐IR spectra of products copolymerized from a CO2/C2H4 system (a), and relative intensities of the carbonyl absorbance (b).magnified imageFT‐IR spectra of products copolymerized from a CO2/C2H4 system (a), and relative intensities of the carbonyl absorbance (b).
