Production of diamond-like carbon powder in nano size

Abstract

Until now, researchers have conducted many studies about diamond-like carbon materials. We saw some shortcomings of a well-known method, and we decided to improve it. First, we performed the electrolysis stage of poly(hydridocarbyne) production. We continued with a pericyclic reaction by adding benzoyl peroxide or 2,2′-azobis(isobutyronitrile). Then, we heated the obtained poly(hydridocarbyne) powders at high temperatures in an argon atmosphere. The product produced according to the literature was the control group, and the others were test groups (E1 and E2). The samples were compared through X-ray diffraction (XRD), Fourier transform infrared (FTIR) and scanning electron microscopy analysis. According to the results, diamond-like carbon powders can be produced in smaller particle sizes. They can be crystallized better by adding a new pericyclic reaction to the production method in the literature. The strength of the XRD peak of the diamond-like material produced with benzoyl peroxide was almost twice the other. The crystalline sizes were 13, 11, and 17 nm for the control group, E1 and E2, respectively. The vibration peaks of diamond-like materials were observed in the FTIR spectrum. In tunnelling electron microscope images, particle sizes of the control group, E1 and E2 were 135, 125 and 88 nm, respectively.
