METHOD FOR MODIFYING HYDROPHILIC SURFACES USING HYDROPHOBIC CERAMIC POWDERS HAVING CORE-SHELL STRUCTURE
The present invention relates to a surface modification method using hydrophobic ceramic powder having a core-shell structure. More specifically, the surface modification method using hydrophobic ceramic powder is performed by coating rare earth oxides (for example, Y_2O_3) having hydrophobic properties on ceramic powder (for example, SiO_2, Al_2O_3) through atomic layer deposition (ALD) to synthesize functional composite powder having a core-shell structure and forming a hydrophobic ceramic film on a target surface based on a spray coating method by using the synthesized functional composite powder. Therefore, the present invention imparts high hydrophobic properties to the surface of a target surface in an efficient and economical method in which the use amount of expensive rare earth oxides is minimized, enables the hydrophobic properties to be maintained at a high temperature, and allows the corresponding film to have excellent hardness and durability.
본 발명은 코어쉘 구조의 소수성 세라믹 파우더를 이용한 표면 개질방법에 관한 것으로, 더욱 상세하게는 소수성 특성을 지닌 희토류 산화물(예컨대, YO)을 원자층 증착법(ALD)을 통해 세라믹 파우더(예컨대, SiO, AlO)에 코팅하여 코어쉘 구조의 기능성 복합 파우더를 합성하고, 이를 이용하여 스프레이식 코팅법으로 대상 표면에 소수성의 세라믹 피막을 형성함으로써, 고가인 희토류 산화물의 사용량을 최소화한 효율적·경제적 방법으로 대상 표면에 높은 소수성 특성을 부여하고, 이러한 소수성 특성이 고온에서도 유지되도록 하며, 해당 피막이 우수한 경도 및 내구성을 보유하도록 한, 코어쉘 구조의 소수성 세라믹 파우더를 이용한 표면 개질방법에 관한 것이다.
