Electrospinning-Based Carbon Nanofibers for Energy and Sensor Applications

Carbon nanofibers are the most basic component of one-dimensional nanometer-scale sp2 carbon. We introduce an electrospinning device capable of manufacturing CNFs from a polymer precursor, and then we introduce the techniques for producing CNFs with a porous and hollow structure by modifying existing electrospinning techniques. This paper also discusses recent findings on the use of CNFs in various structures that have recently developed for sensor electrode materials and energy storage materials.

SYNTHESIS OF CARBON NANOFIBERS BASED ON HUMIC ACID AND POLYACRYONITRILE BY ELECTROSPINNING METHOD

The article describes a method for extracting carbon nanofibers based on humic acid from the Maikuben basin's oxidized coal and polycarlonitrile's polycarlonitrile by electrospinning in laboratory conditions. The elemental composition was determined and the surface morphology of the tested sample was investigated, and the degree of modification of the carbon fiber was discovered. The diameter of the fibers was 117. 5 microns, according to the elemental composition of carbon after oxidation and carbonization, was 87. 75 and 89. 16%. The ratio I / I = 1. 4 shows the degree of graphitization - 23. 9 percent, according to Raman scattering of light of carbonized CNF. The degree of graphitization was revealed by the ratio I / I = 0. 7, with the ratio I / I = 1. 4. The original fibrous structure of the sample was retained after oxidation and carbonization, according to SEM results of CNFs based on humic acid and PAN.

PRODUCTION OF CARBON NANOFIBERS BASED ON COAL TAR AND POLYACRYONITRILE BY ELECTROSPINNING METHOD

The paper describes experiments conducted in a laboratory setting to produce composite fibers based on Shubarkol coal tar and polycarlonitrile. At 300°, u00b0C, the holding time was 1 hour, after which the carbonization process was carried out at 800 °C and subsequent cooling to room temperature was achieved. The degree of graphitization was 15. 98 percent as shown by Raman scattering of light's results. According to the broad bands D and G, CNFs inherently graphitized carbon and amorphous carbon are mixed in amorphous carbon. During carbonization, the ID / IG ratio represents the conversion of disordered carbon to graphite carbon during graphite carbon conversion. The original fibrous structure of CNFs retained the original fibrous structure of the original fibrous structure, according to SEM images of CNFs from CT and PAN. The diameter of nanofibers decreased from 320. 5 - 65. 7 nm to 89-449. 8 nm, according to the manufacturer.
