NOVELTY - Carbon capture material comprises an adsorbent and a micro-encapsulated shell. The adsorbent comprises potassium carbonate aqueous solution, ethanolamine aqueous solution or ethanolamine aqueous solution containing graphene flakes, and the potassium carbonate aqueous solution or the ethanolamine aqueous solution or the ethanolamine aqueous solution containing graphene flakes are prepared by using a microfluidic device. USE - The material is useful for micro-flow control of needle tube. ADVANTAGE - The method: utilizes potassium carbonate aqueous solution, ethanolamine aqueous solution, or ethanolamine aqueous solution containing graphene flakes as an adsorbent for the first time; utilizes microfluidic technology to prepare carbon capture particles; and is fast and economical. The material has particles which have a higher carbon dioxide absorption rate, in particular, the introduction of graphene enables convective motion in the fluid to enhance the adsorption efficiency of nanoparticle-containing adsorbents. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the carbon capture material, comprising (i) preparing micro-encapsulated adsorbent by (ia) using solvents which is water, dissolving potassium carbonate and ethanolamine in water at 25-35 wt.% respectively to obtain potassium carbonate aqueous solution and ethanolamine aqueous solution, adding graphene to ethanolamine aqueous solution, sonicating at 35-45 degrees C for 1-2 hours to ensure that the nanomolecules are evenly distributed in the solvent and obtain ethanolamine aqueous solution containing graphene flakes, and (ib) using the shell as silicone acrylate, adding 3-8 wt.% photoinitiator 2-hydroxy-2-methyl acetone to the silicone acrylate, vacuum-exhausting to remove the foam inside, and (ii) preparing needle tube microchannel by passing the above-mentioned adsorbent and micro-encapsulated shell through a needle tube microfluidic device to form a shell-core double emulsion made of silicone acrylate coated adsorbent, irradiating with ultraviolet rays, and curing to form a carbon capture material.
