초발수 표면을 만들기 위한 마이크로-나노 몰드 제작 공정

초록

In recent materials industry, researches on the technology to manufacture super hydrophobic surface byeffectively controlling the wettability of solid surface are expanding. Research on the fabrication of super hydrophobicsurface has been studied not only for basic research but also for self-cleaning, anti-icing, anti-friction, flow resistancereduction in construction, textile, communication, military and aviation fields. A super hydrophobic surface is defined asa surface having a water droplet contact angle of 150 ° or more. The contact angle is determined by the surface energyand is influenced not only by the chemical properties of the surface but also by the rough structure. In this paper, maskless lithography using DMD, electro etching, anodizing and hot embossing are used to make thepolymer resin PMMA surface super hydrophobic. In the fabrication of microstructure, DMDs are limited by the spacingof microstructure due to the structural limitations of the mirrors. In order to overcome this, maskless lithography usinga transfer mechanism was used in this paper. In this paper, a super hydrophobic surface with micro and nano compositestructure was fabricated. And the wettability characteristics of the micro pattern surface were analyzed.
