METHOD FOR PREPARING FUNCTIONAL POROUS CERAMIC MATERIAL USING DIRECT FOAMING METHOD, AND FUNCTIONAL POROUS CERAMIC MATERIAL

摘要

A method for preparing a functional porous ceramic material by using a direct foaming method of the present invention comprises: a mixing step of preparing a mixture solution by mixing a ceramic powder and an aqueous solution; an injection step of preparing a suspension by injecting a surface treatment agent into the mixture solution; and a reaction step of injecting air by stirring the suspension, thereby preparing a ceramic material in which pores are formed by a reaction between the suspension and the air, wherein the surface treatment agent of the injection step comprises an amphiphile.
