Summary: | Disclosed is a waterproofing method for a device. According to the present invention, the method comprises: a step (i) of combining metal oxide nanoparticles with a self-assembled monolayer (SAM); a step (ii) of coating the surface of the device with the metal oxide nanoparticles such that the surface of the device has super-hydrophobic properties; and a step (iii) of selectively irradiating the surface of the device having super-hydrophobic properties with ultraviolet rays, wherein a surface portion of the device, which does not require interception of moisture, is converted into a hydrophilic region by irradiating the ultraviolet rays, a surface portion of the device, which requires interception of moisture, is maintained as a super-hydrophobic region by being blocked from the ultraviolet rays, and the super-hydrophobic region and the hydrophilic region are formed on the surface of the device in an amount of at least one. Thus, introduced moisture can be effectively excluded, collected, and removed.
본 발명은 소자의 방수처리 방법을 개시한다. 본 발명에 의한 상기 방법은 (i) 금속산화물 나노입자를 자기조립단분자막(SAM)과 결합시키는 단계와, (ii) 소자의 표면에 상기 금속산화물 나노입자를 코팅하여 상기 소자의 표면이 초소수성을 갖는 단계와, (iii) 상기 초소수성을 갖는 소자의 표면에 자외선을 선택적으로 조사하되 수분의 차단이 필요없는 상기 소자의 표면 부위는 상기 자외선을 조사하여 친수성 영역으로 전환시키고 수분의 차단이 요구되는 상기 소자의 표면 부위는 상기 자외선의 조사로부터 차폐시켜 초소수성 영역을 유지시키며 상기 초소수성 영역과 친수성 영역은 상기 소자의 표면에 각각 하나 이상 형성되는 단계를 포함한다. |
