Surface modification and submicron structure of carbon fibers through high current pulse

Formation of Surface Morphology in Polyacrylonitrile (PAN) Fibers during Wet-Spinning

“…Interfacial adhesion between reinforcement and matrix is a key factor in determining the properties of the resultant composite because good interfacial adhesion results in effective stress transition. Many methods have been applied to modify the surface of carbon fibers to improve the interfacial sheer stress between carbon fibers and the matrix [5][6][7][8][9][10][11]. It was usually believed that chemical bonding was more important than physical bonding for carbon fiber composites.…”

Cold atmospheric pressure plasma jet prepares TiO2 coating on carbon fibre for field emission and explosive electron emission

“…Recently, a hybrid disordered carbon fibre cathode with ideal electric resistance was reported by Lu et al [12]. To date, carbon fibres are considered one of the most appropriate candidates for explosive emission cathodes to generate electron beams with high current densities due to its outstanding vacuum compatibility, fast turn-on, low plasma expansion velocity and operational stability [1][2][3]13]. The bottleneck of developing carbon fibre cathodes for explosive electron emission is generating largearea cathode plasma with a rapid turn-on time.…”

A novel approach to functionalise pristine unsized carbon fibre using in situ generated diazonium species to enhance interfacial shear strength

“…21 Incorporation of chemical treatment to further improve brematrix adhesion and successful load transfer has been of both academic and industrial interest in the drive toward a new generation of high-performance carbon bre composites. 22 Investigations which have been undertaken to chemically modify the surface of carbon bre have encompassed a wide variety of solution phase, 23,24 atmospheric, 25 plasma, 26 and electrolytic treatments. 27,28 The majority of these efforts have been directed toward increasing density of oxygenated species (typically COOH, C]O and OH) on the surface by oxidation, increasing the hydrophilicity or "wettability" of the bre, while simultaneously increasing the potential occurrence of intermolecular interactions (such as hydrogen bonding) between the bre and matrix.…”
