초록

그래핀의 저차원 구조에서 기인하는 우수한 전기적/기계적 특성을 지닌 3차원 그래핀 나노 구조체는 높은 다공성과 비표면적을 가지고 있기 때문에 전기화학 에너지 저장 전극 물질로 각광을 받고 있다. 또한 도파민은 카테콜아민 구조를 갖고 있어 다양한 유무기 재료와의 결합력이 뛰어나고, 소수성 재료를 친수성으로 개질시킬 수 있는 다기능 소재이다. 이에 본 연구에서는 도파민을 3차원 그래핀 나노 구조체에 코팅하여, 전해질과의 젖음성을 증대시켜 전기화학 전극의 비축전용량을 개선하고, 3차원 나노 네트워크 간 결합력을 올려 기계적 압축 특성을 증가시키고자 하였다. 연구 결과, 도파민이 코팅된 3차원 그래핀 나노 구조체는 전기화학 비축전용량이 51.5%, 압축 응력은 59.6%로 증가하는 높은 개선 효과를 나타내었다.

Inherited the excellent electrical and mechanical properties based on the low dimensional structure of graphene, three-dimensional graphene nanostructures have gathered great attention as electrochemical energy storage electrodes owing to their high porosity and large specific surface area. Also, having the catecholamine structure, dopamine has been regarded as a multifunctional material to possess high affinity to various organic/inorganic materials and to modify a hydrophobic surface to a hydrophilic one. In this work, through coating dopamine on the three-dimensional graphene nanostructure, we tried to increase the specific capacitance by enhancing the wettability with electrolyte and to improve the mechanical compressive property by strengthening the nano-architecture. As a result, the dopamine-coated nanostructure exhibited significant improvement on the specific capacitance (51.5% increase) and compressive stress (59.6% increase).
