Pitch-based carbon fibers: preparation and applications

Abstract

Attention to carbon fiber (CF) conditioned by their unique physicochemical, mechanical and electrical properties, which makes them in demand in various fields of activity. Today there are several kinds of carbon fibers, most of which (about 90%) are made of polyacrylonitrile (PAN). Despite the fact that carbon fibers are produced from several types of different precursors, their widespread commercial use is limited by the high cost of the product. Has, many research and engineering group seek to reduce the cost of production by using cheap carbon raw materials. A likely solution to this problem is the exploitation of coal, petroleum and coal tar as an effective progenitor for CF production. This review discusses neoteric accomplishment in CF synthesis using various carbon pitches. The possibility of obtaining carbon fibers based on resin with the addition of PAN is presented, and the prospects for their use in energy storage systems and various reinforced composite materials are described in detail.

Carbon/NiO Compositional Fibers

“…Scanning electron microscopy allows studying the morphology and topography of the sample at high resolution. Previous work in this area [22,23] showed that the optimal temperature for heat treatment of CT corresponds to a temperature of 400 °C. After heat treatment, coal tar passes from a viscous state to a condensed solid state.…”
