TECHNICAL FIELD The present invention relates to a composite powder improved in water repellency and oil absorption by impregnating inorganic powder particles homogeneously in a superhydrophobic porous polymer, and relates to a composite powder obtained by spray drying (Spray Drying) or electrospray The composite powder produced by the one step spraying process of Electro-Spraying increases the porosity of porous polymethyl methacrylate (PMMA) and increases the porosity of titanium dioxide (TiO2) Nanoparticles are uniformly impregnated to realize super water repellency and maximize oil absorption performance.本発明は、超撥水性多孔性高分子に無機粉体粒子を均一に含浸させて撥水性と吸油性が向上された複合粉体に係り、本発明の噴霧乾燥(Spray Drying)または電気噴霧(Electro-Spraying)のワンステップ噴霧工程で製造された複合粉体は、多孔性ポリメチルメタクリレート(PMMA)の孔隙率を増大させ、二酸化チタン(TiO2)ナノ粒子が均一に含浸されることで、超撥水性を実現し、吸油性能を極大化する効果を示す。
