A green approach towards the production of Zinc Oxide scaffolds

Abstract

Abstract-We report a novel method for the fabrication of porous zinc oxide scaffolds by a scalable supercritical CO 2 (sc-CO 2 ) based nebulization process. This process consists of mixing of sc-CO 2 stream with zinc acetate solution under supercritical conditions. This process consists of evaporation of CO 2 enriched water micro-droplets deposited from an aerosol onto heated substrates. Our process is readily scalable to produce zinc oxide scaffolds on a manufacturing scale.
