METHOD FOR PREPARING SCAFFOLD BY USING SALT LEACHING AND IMMERSION PRECIPITATION METHODS, AND SCAFFOLD THEREOF

摘要

A method for preparing a scaffold having high porosity and high pore interconnectivity by simultaneously using an immersion precipitation method, which is a type of phase transfer method, and a salt leaching method, comprises a step of dissolving a scaffold material in an organic solvent mixed with insoluble salt particles, removing the organic solvent through solvent exchange with a non-solvent, and then removing the salt particles with distilled water. Thereafter, micropores are formed in the place where the organic solvent is removed, macropores are formed in the place where the salt particles are removed, and the micropores and the macropores are connected to each other. Therefore, provided is a scaffold, which has micropores and macropores connected to each other, is porous and has high pore interconnectivity.
