A novel method for synthesizing ordered macroporous polymers is presented. Simply irradiating an electron beam onto colloidal polymer crystals generates regularly ordered macroporous polymers. No post-treatment is required for the formation of porous polymers. In addition, arbitrarily shaped two- and three-dimensional macroporous polymers of tunable pore sizes are fabricated via the electron-irradiation method.
