Synthesis and analysis of flakes graphene oxide

Abstract

The presented article is devoted to the synthesis and analysis of flakes graphene oxide obtained by the Hammers method. The synthesized flakes graphene oxide was studied using SEM, EDX, X-ray diffraction, Raman spectroscopy, element analysis, temperature dependent of resistance and IR spectroscopy. As a result of calculating the results of X-ray analysis according to the Debye-Scherer’s formula, the thickness of graphite flakes was about 12,9nm and the number of layers was 38. The result of the Raman analysis show that high quality flakes grapheme oxide was obtained. Based on the result of elementary analysis of grapheme oxide mass, the C/O ratio was determined to be 1,42. The grapheme layers inside the sample were 3,31nm thick and 14,8nm long by scanning electron microscope. The temperature variation of the resistance was determined. IR spectroscopy shows the results of the absorption of electromagnetic radiation in the infrared range by atomic groups of reduced grapheme oxide and the excitation of the molecule by light quanta. When a molecule is irradiated with infrared radiation, it is shown that only quantum absorption quantities are formed according to the frequencies of the molecules.

X-ray analysis of graphene based materials

“…No 151 deposited on various substrates and thin films, which has great potential for wide application in the field of microelectronics, integrated circuit elements, transparent conductive films, and integrated circuits, elements and composite materials. materials , solar energy and biomedicine (due to their more sensitive properties) make them useful [4,8,12]. As a result of our numerous experiments, we came to the conclusion that the use of the Hammer method helped us get better material.…”

“…In connection with the significant influence of the graphene synthesis method on its final physical properties, it seems appropriate to consider in detail the most common methods for forming samples of this material [11][12][13][14][15][16][17][18].…”

“…The advantage of our material is that it can be synthesized more economically by oxidizing large amounts of graphite crystals. Because of these oxygen-containing groups, this material is hydrophilic and can be dissolved in many solvents [18]. The main feature of the materials obtained as a result of experiments is their ability to be uniformly…”

Electrical and Photoelectric Properties of P-CDS/P-Cdte/Znte/ZNCDS Heterojunctions

“…Not all photogenerated electrons reach the space charge field, which results in a decrease in the rate of short-wave stimulation. A sharp decrease in the sensitivity of the sample in the short-wave range of the spectrum is due to the recombination of the resulting charge carriers in the volume of the Zn1-xCdxS layer, not reaching the space charge region in time, that is, absorption of light [6,9,10]. The decrease in sensitivity in the long-wavelength region indicates a decrease in the p-CdS/p-CdTe/ZnTe/Zn1-xCdxS aggregation coefficient and the presence of adhesion centers in Zn1-xCdxS.…”

Synthesis and analysis of nanostructured graphene oxide

“…Since we live in the 21st century, most composite materials (polymers/GO nanoparticles, biodegradable polymers/GO nanoparticles) are used as additives to building materials to improve physical and mechanical properties and also for drug delivery [4,5,6]. Analyzes of the few layer grapheme oxide sample were performed witt various research methods [8][9][10][11][12]. After doping the grapheme -based samples with various metals, its analysis was conducted and unique result were obtained [13][14][15].…”
