Abstract

In this study, nanodiamod's surface have formed carboxyl, hydroxyl, amine radical for the purpose of use of nanodiamond synthesized by detonation, and then it has widely stable dispersion and slowly sedimentation in solvent. Thus nanodiamonds obtained by chemical treatment were used to analyze the structure, surface statement, particle size and sedimentation specification in solvent for method X-ray diffration(XRD), scanning electron microscope energy diffraction spectroscopy(SEM-EDS), Fourier transform infrared spectroscopy (FTIR), automic force microscope(AFM).

폭발법으로 얻어진 나노다이아몬드가 용매 내에 균일하게 분산되고, 일정 시간 침강이 이루어지지 않고 유지할 수 있도록 하고자, 표면에 카르복시기, 하이드록시기, 아민기 등의 기능기를 형성시킴으로써 나노다이아몬드의 활용성을 증대시키고자 하였다. 화학반응을 통하여 표면에 형성된 기능기, 입자의 크기 모양 등의 확인은 적외선흡수 스펙트럼과, X레이회절, 전자현미경, 원자현미경으로 관찰하였고, 용매의 종류에 따른 분산 특성을 조사하였다.
