Abstract: In a halloysite-based composite hemostatic material, hydroxylated halloysite is used as a carrier, and the carrier is loaded with aggregation-induced emission (AIE) nanoparticles. The preparation method includes: preparing the hydroxylated halloysite into a hydroxylated halloysite suspension; preparing the AIE nanoparticles into an AIE nanoparticle solution; and thoroughly mixing the hydroxylated halloysite suspension with the AIE nanoparticle solution at a specified temperature and a specified oscillation speed, centrifuging a resulting mixed solution, and lyophilizing a resulting precipitate to obtain an AIE nanoparticles-loaded modified halloysite composite, which is the halloysite-based composite hemostatic material.

Abstract: A kaolin-based hemostatic gauze comprises: a medical non-woven fabric as a carrier; and a kaolin-containing composite hemostatic material loaded on the medical non-woven fabric, wherein kaolin serves as a carrier in the kaolin-containing composite hemostatic material, the kaolin is doped with Ce and ?-Fe2O3 is loaded on the Kaolin. A method for preparing the kaolin-based hemostatic gauze, includes: S1: preparing the kaolin-containing composite hemostatic material; S2: preparing the kaolin-containing composite hemostatic material into a suspension; S3: impregnating the medical non-woven fabric with the suspension thoroughly stirred, wherein upper and lower sides of the medical non-woven fabric each are impregnated once; and S4: pressing and oven-drying an impregnated medical non-woven fabric to obtain the kaolin-based hemostatic gauze.
