Abstract
A single-step synthetic method for preparing hydrogel hollow capsules on a superhydrophobic surface was successfully developed. Aqueous microdroplets of a mixture of hydrogel monomer and cross-linker solutions were deposited on the superhydrophobic surface, which was situated under the hydrocarbon oil layer containing photoinitiator. When exposed to UV light, the aqueous microdroplets were converted to hollow capsules with a polymerized hydrogel shell, formed due to the diffusion of photoinitiators at the oil/water interface. This method for producing hydrogel hollow capsules on superhydrophobic surfaces is simple and efficient, rendering easy encapsulation of colloidal nanoparticles, drugs, or biological cells.

초소수성 표면을 이용하여 간단하고 빠르게 하이드로젤 중공 캡슐을 제작하는 새로운 방법을 개발하였다. 광개시제를 포함하는 탄화수소 오일 층에 초소수성 성질을 가지는 기판을 위치시키고, 하이드로젤 단량체와 가교제를 함유한 마이크로 리터 부피의 droplet을 초소수성 표면에 형성하였다. UV light를 초소수성 표면에 조사하여 droplet 의 물과 오일 계면에서 광개시제의 확산으로 일어난 광중합반응을 통해 형성된 하이드로젤 중공 캡슐을 제조하였다. 이러한 간단하고 효과적인 초소수성 표면 위에서 하이드로젤 중공 캡슐을 제작하는 방법은 콜로이드 나노 입자, 약물, 또는 세포 등을 쉽게 캡슐화하는데 활용될 것으로 전망된다.
