초록

이 연구에서 우리는 3차원 계층적 나노구조화된 유/무기 복합 표면을 가진 소수성 코팅/필름을 제조하는 방법을 제안한다. 먼저 근접장 나노패터닝(PnP)이라 불리는 첨단 포토리소그래피 기술을 통해 에폭시 기반의 대면적 3차원 정렬 나노다공성 템플릿을 준비하였다. 이후, 딥 코팅을 통해 평균 직경이 22 nm인 실리카 나노입자를 템플릿에 조밀하게 함침시켜 계층적 구조화된 표면을 구현하였다. 표면에 공존하는 마이크로 및 나노 스케일 거칠기로 인해, 제조된 복합 필름은 대조군에 비해 물에 대한 높은 접촉각(>137도)을 나타내었다. 따라서 본 연구를 통해 개발된 소재 및 공정은 전통적인 코팅/필름 분야에서 다양하게 활용될 수 있을 것으로 기대된다.

In this study, we propose a method for fabricating hydrophobic coatings/films with three-dimensional (3D) hierarchical nanostructured organic/inorganic composite surfaces. An epoxy-based, large-area 3D ordered nanoporous template is first prepared through an advanced photolithography technique called Proximity-field nanoPatterning (PnP). Then, a hierarchically structured surface is generated by densely impregnating the template with silica nanoparticles with an average diameter of 22 nm through dip coating. Due to the coexisting micro- and nano-scale roughness on the surface, the fabricated composite film exhibits a higher contact angle (>137 degrees) for water droplets compared to the reference samples. Therefore, it is expected that the materials and processes developed through this study can be used in various ways in the traditional coating/film field.
