Abstract
The present invention relates to a method for producing a three-dimensional ordered porous microstructure. In the method of the invention where the three-dimensional ordered microstructure is produced using the colloidal crystal templating process, the three-dimensional ordered microstructure thus formed is subjected to heat treatment to soften the particles, so as to effectively increase the contact between orderly arranged particles while removing the solvent used to suspend the particles. The present invention further relates to a monolithic column produced thereby. Compared to the monolithic columns produced by conventional methods, the monolithic column according to the invention is characterized in having a higher aspect ratio and a higher pore regularity, while the connecting pores in the column are relatively large in pore size.
