Carbon capture using wettable polymeric materials
The granted patent US12048895B2 outlines a method for enhancing carbon capture processes using a composite material that includes a polymeric substrate and a silicate coating. The silicate coating, which contains silicate particles that are covalently bonded to the polymeric substrate, is designed to facilitate the transfer of carbon dioxide from a gas phase to a liquid phase during the carbon capture process. The polymeric substrate can be made from various materials, including polyvinyl chloride, polyethylene, and biopolymers, and may take the form of films, woven, or nonwoven fabrics. The silicate coating can be applied through a flame-pyrolytic deposition process and may include silicon dioxide, which enhances the material's surface properties.
Additionally, the method specifies that the carbon capture process can involve a direct air capture approach, where the liquid phase may consist of an alkali metal hydroxide that converts to an alkali metal carbonate upon exposure to carbon dioxide. The patent also describes the potential for the material to consist of stacked sheets, creating a high surface area for gas-liquid contact. Furthermore, the polymeric substrate may include a surface layer with a passivating compound to stabilize the substrate or silicate coating. The invention emphasizes the importance of achieving a more wettable surface and higher surface energy in the silicate coating, which are intended to be permanent features, thereby improving the efficiency of the carbon capture process.
