“…In general, surface treatment includes wetting methods (liquid oxidation) such as sulfuric acid and nitric acid [ 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 ], dry methods (dry gaseous oxidation) [ 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 ] such as high-temperature treatment in an atmosphere of oxidizing gas or inert gas, electric oxidation methods [ 3 , 30 , 31 , 32 ], the plasma method [ 33 , 34 , 35 , 36 , 37 , 38 , 39 ] of surface treatment using ionized gas, and exposure to strong energy such as ozone and ultraviolet rays (energetic ions oxidation) [ 40 , 41 , 42 ].…”

In this study, the chemical state change of recycled carbon fiber (rCF) surfaces and the mechanism of the oxygen functional groups according to nitric acid treatment at various times and temperatures were investigated to upcycle the carbon fiber recovered from used carbon composite. When treated with nitric acid at 25 °C, the carbon fiber surface demonstrated the same tensile properties as untreated carbon fiber (CF) for up to 5 h, and the oxygen functional group and polar surface energy of C–O (hydroxyl group) and C=O (carbonyl group) increased slightly compared to the untreated CF up to 5 h. On the other hand, at 100 °C, the tensile properties slightly decreased compared to untreated CF up to 5 h, and the amount of C–O and C=O decreased and the amount of O=C–O (lactone group) started to increase until 1 h. After 1 h, the amount of C-O and C=O decreased significantly, and the amount of O=C–O increased rapidly. At 5 h, the amount of oxygen functional groups increased by 92%, and the polar surface energy increased by 200% compared to desized CF. It was determined that the interfacial bonding force increased the most because the oxygen functional group, O=C–O, increased greatly at 100 °C and 5 h.

“…Polymers 2022, 14, 2412 2 of 13 In general, the surface treatments of carbon fibers include a wet method (liquid oxidation) [16,[18][19][20][21][22] in which the surface is treated with an acid such as sulfuric acid or nitric acid, a dry method (dry gaseous oxidation) in which the surface is treated at a high temperature in an oxidizing gas or inert gas atmosphere [9,[23][24][25][26][27], electrochemical oxidation [4,7,28], a plasma method of surface treatment using ionized gas [29][30][31], or energetic ion oxidation that exposes them to strong energy such as ozone and ultraviolet rays [3,[32][33][34]. It is known that heat treatment, which is a dry method in the surface treatment methods of carbon fibers, changes the properties of the carbon fibers according to the change in the atmosphere, temperature, and treatment time [23,24].…”

In this study, carbon fibers were heat-treated in a nitrogen and oxygen atmosphere according to temperature to elucidate the mechanism of chemical state changes and oxygen functional group changes on the carbon fiber surface by analyzing the mechanical and chemical properties of carbon fibers. Carbon fibers before and after heat treatment were analyzed using FE-SEM (Field Emission Scanning), UTM (Universal Tensile Testers), XPS (X-ray Photoelectron Spectroscopy), and surface-free energy. In the nitrogen atmosphere, which is an inert gas, the tensile strength was equivalent to that of the virgin up to 500 °C but decreased to 71% with respect to the virgin at 1000 °C. Furthermore, as the temperature increased from room temperature to 1000 °C, the oxygen functional group and the polar free energy gradually decreased compared with the virgin. On the other hand, in the oxygen atmosphere, which is an active gas, the tensile properties were not significantly different from those of the virgin up to 300 °C but gradually decreased at 500 °C. Above 600 °C, the carbon fibers deteriorated, and measurement was impossible. The oxygen functional group decreased at 300 °C, but above 300 °C, among the oxygen functional groups, the hydroxyl group and the carbonyl group increased. Furthermore, the lactone group formed and rapidly increased compared with the virgin, and the polar free energy increased as the temperature increased.

“…It has been mainly used in medical applications, printed electronics, and as a substitute for heat treatment ( Bitter, 2000 ; Babilas et al., 2010 ; Kim et al., 2009 ; Kang et al., 2011 ; Jiu et al., 2012 ; Youn et al., 2018 ). Recently, surface modification experiments have been conducted, for example, to reduce graphene oxide or improve the adhesion of CF-reinforced plastics ( Al-Hamry et al., 2016 ; Pei and Li, 2017 ; Kim et al., 2021 ). However, there have been only few studies on the functionalization of CFs via IPL irradiation ( Lee et al., 2017 ).…”
