Abstract

See full text

The present invention relates to composite powder having enhanced water repellency and oil absorbency by means of even impregnation of inorganic powder particles with a super-water-repellent porous polymer. The composite powder prepared by means of a one-step spraying procedure of electro-spraying or spray drying, according to the present invention, shows super water repellency and maximized oil absorbency by means of increased porosity of porous polymethyl methacrylate (PMMA) and even impregnation with titanium dioxide (TiO2) nanoparticles.
