Abstract

Nanodiamond is a relatively new nanomaterial with broad prospects for application. In this paper, a variety of methods were used to analyze comprehensively chemicophysics properties of the detonation monocrystalline and synthetic polycrystalline nanodiamond, XRD spectroscopy, EDS, HRTEM, FTIR, Raman spectroscopy, TGA-DTA and BET. The results show that the monocryctalline detonation nanodiamond particles are spherical or elliptical shape of 4nm ~ 6nm grain size and the polycryctalline synthetic nanodiamond particles are angular shape of 80nm ~ 120nm grain size. The surface of the monocrystalline and polycrystalline nanodiamond contain hydroxy, carbonyl, carboxyl, ether-based resin, and other functional groups. The phase transition temperature of the monocrystalline detonation nanodiamond in the $N_2$ is about $650^{\circ}C$.

나노다이아몬드는 넓은 적용성 측면을 고려한다면 상대적으로 신물질이라 할 수 있다. 본 연구에서는 XRD, EDS, HRTEM, FTIR, Raman 분광기, 열분석 장치와 BET 측정 장치와 같은 다양한 장비를 통해 단결정 폭발 나노다이아몬드와 다결정 합성 나노다이아몬드의 물리화학적 특성들을 고찰하였다. 단결정 폭발 나노다이아몬드는 4nm ~ 6nm 크기의 구형이나 타원 모양이지만, 다결정 합성 다이아몬드는 80nm ~ 120nm 크기의 각이 진 입체도형 모양이다. 단결정과 다결정 나노다이아몬드의 표면은 수산기, 카보닐기, 카복실기 등과 같은 다양한 관능기를 가지고 있다. 질소분위기 하에서 단결정 폭발 나노다이아몬드의 상전이 온도는 대략 $650^{\circ}C$이었다.
