초록

본 연구에서는 유기적으로 기능화된 은 나노 입자들은 공기와 물이 형성하는 계면에서 자발적 조립 과정을 통해 새로운 2차원 상부 구조들(superstructures)을 생성하는 것을 발견하였다. 상부 구조의 분석은 금속 나노 입자의 심형과 입자계면에 결합된 유기 분자의 크기를 바꿈으로써 입자 간 특징적 상호 작용(characteristic inter-particle interaction)을 조절할 수 있고 이들 사이의 미묘한 상호 작용(subtle interplay)을 통해 은 나노 입자의 2차원 조립이 발생함을 시사한다. 본 연구를 통해 발견한 새로운 구조들은 기능성 나노 소재, 촉매 및 소자 응용 분야에 매우 중요한 잠재적 용도가 있을 것이라 사료된다.

We report organically functionalized Ag nanoparticles spontaneously form two-dimensional (2D) novel superstructures at the air-water interface. Analysis of the superstructures suggests that the 2D assembly of Ag nanoparticles originates from a subtle interplay between characteristic inter-particle interactions that can be readily controlled by changing the sizes of nanoparticle metal core and surfactants. Such structures have potential uses in nanostructured functional materials, catalysis, and device applications.
