“…[ 1–4 ] However, due to the nonpolar and highly crystallized graphite layer structure and the lack of functional groups with chemical activity on the surface, the carbon fibers exhibit chemical inertia, resulting in poor bonding between carbon fibers and matrix. [ 5,6 ] Therefore, the application of carbon fibers in special working conditions is greatly limited because the excellent properties of composites are difficult to play. [ 7 ] Therefore, it is of great significance to improve the surface activity of carbon fibers by surface modification technology and strengthen the interfacial properties between carbon fibers and matrix materials.…”

On the basis of a thin‐wire contact electrode structure, a nonuniform electric field is designed to realize diffuse discharge in atmospheric air. A new method of high‐efficiency treatment of carbon fiber fabrics by glow discharge plasmas at low discharge voltage is proposed. Through this method, carbon fiber fabrics are directly used as electrodes, the plasmas are directly formed on the surface, and a strong electric field region can be formed on the surface of carbon fiber fabrics. The high‐active plasmas generated in this study can not only introduce nitrogen functional groups that are difficult to be introduced by traditional air plasma treatment methods and a large number of oxygen functional groups on the surface of carbon fiber fabrics but also improve the surface roughness and wettability of the material. In addition, the important effects of surface electric field intensity and plasma treatment time on the modification effect were investigated. It lays a good technical foundation for the industrial application of carbon fiber surface modification with high efficiency and continuity in atmospheric air.

“…The surface of a CF is similar to that of a graphite structure, which is inert and water-resistant. These qualities weaken the adhesion of CFs to other substrates, impeding the manufacture of composite materials with excellent performance [6][7][8][9]. Accordingly, the surface of the CFs is treated to improve the reactivity and wetness ability of the surface, enhancing the bond strength of the composite interface [10][11][12].…”

In this study, carbon fibers (CFs) were used as toughening materials to improve the mechanical properties of cement stone. The surfaces of the CFs were treated with concentrated nitric acid and sodium hypochlorite to increase the interfacial adhesion between the CFs and the cement. The CFs subjected to surface treatment were evaluated by scanning electron microscopy and infrared analysis to find a significant increase in the number of oxygen-containing groups on the surface. The CFs subjected to surface treatment were added to the cement matrix. The effect of the modified CFs on the mechanical properties of the cement matrix was evaluated by testing the means of mechanical properties. The maximum tensile strength, maximum compressive strength, and ultimate strain of the enhanced cement stone of the CFs treated with sodium hypochlorite increased by 68.2%, 12.0%, and 4.4%, respectively. The maximum tensile strength, maximum compressive strength, and ultimate strain of the enhanced cement stone of the CFs treated with concentrated nitric acid increased by 72.7%, 14.7%, and 4.5%, respectively. The addition of CFs to the cement stone exerted no effect on the type of cement hydration products, as determined by infrared analysis and X-ray diffraction. The toughening mechanism of the modified CFs added to the cement stone was ultimately explored, and the bridging effect, deflection effect, and pull-out effect of cracks were evaluated.
