Carbon fiber-reinforced plastics (CFRPs) possess pronounced anisotropic properties, necessitating advancements in through-thickness electrical conductivity and other functionalities without compromising mechanical integrity. MXenes, as an emerging family of two-dimensional nanomaterials, have demonstrated significant potential for enhancement modification in this area. However, achieving uniform distribution and effective utilization on a large scale with low filler content has posed a significant challenge. Herein, a highly lightweight, flexible, and functional Ti 3 C 2 T x / poly(3,4-ethylene-dioxythiophene) poly (styrene sulfonate) (PEDOT: PSS) /Ammonium polyphosphate (APP) reclaimed carbon fiber (rCF) veil reinforced plastics (MPA-rCFRPs) was fabricated through large-scale vacuum-assisted filtration and autoclave technology. The modified MPA-rCFRPs have exhibited substantial improvements in electromagnetic shielding with MXene additive amounts as low as 0.24 %–1.07 %, increasing the electro-magnetic interference shielding effectiveness (EMI SE) to 87.12 dB, improved by 350.02 %. Remarkably, the through-thickness electrical conductivity of MPA-rCFRPs exhibited a 767.14 % improvement, escalating from 19.73 S/m to 151.41 S/m. Meanwhile, the modified composites have exhibited enhanced photothermal, electrothermal, and flame-retardant properties, and the above improvements have not shown a significant impact on the mechanical properties of the material. This work represents a practical solution for the construction of large-scale MXene-based carbon fiber composites and opens the door to functional reutilization of rCF materials.

Along with the massive application of the carbon fiber reinforced polymer (CFRP), the quantity of CFRP wastes are rapidly increasing, becoming an urgent issue to be resolved. Here, an effective solvent-free treatment method was proposed to recycle carbon fiber/epoxy composite wastes and reclaim the carbon fibers with high performance. The resin matrix composed of tetra-functional epoxy/aromatic amine system which is widely used in aircraft components can be decomposed rapidly in KCl/ZnCl 2 molten salts due to triggered C-N bond cleavage under the catalytic effect of cations at 350 °C in 90 min, and TiO 2 can facilitate the removal of pyrolysis carbon within 10 min subsequently. In addition, the reclaimed fibers had similar chemical structure and graphitization degree to the commercial fibers, and also the tensile strength retention rate was up to 97.8%. The reclaimed carbon fibers showed a comparable reinforcing effect for the polypropylene in comparison to the commercial fibers, without visible influence on processability, thermal stability and crystallization behavior of matrix, showing valuable application potential in the field of composite materials. Therefore, this study devised a novel high-efficiency technique applicable for industry to reclaim high-performance carbon fibers from epoxy composite wastes under a mild condition, which showed a significant application value in term of the environmental protection and sustainable development.

Carbon fibers (CFs) are widely used in cutting-edge and civilian fields due to their excellent comprehensive properties such as high strength and high modulus, superior corrosion and friction resistances, excellent thermal stability, light weight, and high electrical conductivity. However, their natural ultra-black appearance is difficult to meet the aesthetic needs of today's civilian sector and the need for optical stealth in the military field. In addition, conventional coloring methods are difficult to effectively adhere to CF surfaces due to high crystallinity and highly inert surface caused by their graphite-like structure. In this work, inspired by the nacre structural color of pearls, colored CFs with 1D photonic crystal structure are prepared by cyclically depositing amorphous (Al 2 O 3 + TiO 2 ) layers on the surface of carbon CFs through atomic layer deposition (ALD). The obtained CFs exhibit brilliant colors and excellent environmental durability in extreme environments. Moreover, the colored CFs also exhibit high EMI shielding effectiveness (45 dB) and optical stealth properties, which can be used in emerging optical devices and electromagnetic and optical stealth equipment.

Our previous work has shown that the amino group is beneficial to improve the interface properties of PPBES/CF composites. However, the existing methods for introducing amino groups have many reaction steps, long reaction time and harsh reaction conditions. A one-step efficient click reaction can effectively avoid the above disadvantages. In this paper, 2-aminoethanethiol (AET) was grafted to CF via a thiol-ene click reaction. The reaction time has been reduced from over 9 h to just 1.5 h. The successful introduction of amino group into CF was testified by FTIR, Raman and XPS . The influence of different ratios of CF:AET on the interfacial properties of the composites was studied emphatically. When CF: AET was 1:3 (T3), the composite exhibited optimal mechanical properties . The ILSS and flexural strength of the resulting composite increased by 24.45% and 33.1%, respectively. The T g of the PPBES/T3 composite was increased to 242 °C as verified by DMA .

Chitin-based carbon fibers (CCFs) and Fe 3 O 4 /CCFs composites are prepared by simple carbonization at different temperatures, which are used as gas sensors for the first time. The effect of carbonization temperatures on the morphology, functional groups, composition , defects, conductivity and gas sensing performance of CCFs and Fe 3 O 4 /CCFs was investigated. The formation of Fe 3 O 4 nanoparticles and the conversion of chitin to carbon material during carbonization were also analyzed. It was found that the structure and gas sensing performance of CCFs and Fe 3 O 4 /CCFs could be controlled by adjusting carbonization temperature. Furthermore, compared with CCFs, the Fe 3 O 4 /CCFs composite showed better gas sensitivity due to the lots of heterojunctions between Fe 3 O 4 and CCFs. The response time and recovery time of the optimized sensor are no more than 30 s and 5 s, respectively. By controlling the carbonation temperature, the controlled CCFs and Fe 3 O 4 /CCFs showed good long-term stability, and the degradation of response is less than 10 % within three months. What’s more, due to the different gas sensing performances, the CCFs and Fe 3 O 4 /CCFs materials prepared at different temperatures were prepared into sensor arrays, which realized the discriminative detection of a variety of target analytes at normal temperature.

Compared with traditional metal materials, carbon-based materials have the advantages of low density, high conductivity, good chemical stability, etc., and can be used as reliable alternative materials in various fields. Among them, the carbon fiber conductive network constructed by electrospinning technology has the advantages of high porosity, high specific surface area and rich heterogeneous interface. In order to further improve the conductivity and mechanical properties of pure carbon fiber films, tantalum carbide (TaC) nanoparticles were selected as conductive fillers. The crystallization degree, electrical and mechanical properties of electrospun TaC/C nanofibers at different temperatures were investigated. As the carbonization temperature increases, the crystallization degree and electrical conductivity of the sample also increases, while the growth trend of electrical conductivity is markedly slowed. The best mechanical properties of 12.39 MPa was achieved when the carbonization temperature was 1200 °C. Finally, through comprehensive analysis and comparison, it can be concluded that a carbonization temperature of 1200 °C is the optimum.Keywords:electrospinning;electrical property;pyrolysis temperature;carbonization

Carbon fiber reinforced thermosetting polymer composites have been widely used in industrial fields, such as wind blades, aerospace and automobiles. However, it is extremely hard to degrade their waste due to the insoluble and infusible crosslinked networks. A solvothermal method is proposed to degrade carbon fiber reinforced vinyl ester resin composite (CF/VER) in this paper. The degradation reaction was conducted in a teflon-lined autoclave at 160 ℃ to 240 ℃ for 60 min to 180 min using isopropanol and acetone as solvents. NaOH or KOH were added to efficiently accelerate degradation process. Degradation ratio up to 99.96% was achieved. Furthermore, a multi-step degradation mechanism was put forward based on FT-IR and GC/MS analysis of degradation products. SEM, FT-IR, and XPS analysis of recycled carbon fibers (RFs) revealed that resin was nearly completely removed. Furthermore, contact angle measurement showed surface wettability of RFs was enhanced. XRD and Raman spectra further verified microstructure of RFs was not damaged drastically. Besides, reusing of degradation products and RFs was explored. Epoxy resin cured with degradation products exhibited excellent performances. Meanwhile, flexural strength tests and SEM images of fracture surfaces showed RFs reinforced epoxy resin composites had superior mechanical strength due to stronger interfaces between fibers and resin. Therefore, an efficient and closed-loop recycling process demonstrated in this manuscript provides a new pathway for degradation and reuse of CF/VER.

Photocatalytic water splitting by semiconductors is considered a promising and cost-effective method for achieving sustainable hydrogen production. In this study, a CF/SrTiO3/In2O3photocatalytic material with a double-layer core–shell structure was developed. The experimental results indicated that the produced CF/SrTiO3/In2O3composite fiber displayed superior photocatalytic hydrogen production performance, achieving a hydrogen evolution rate of approximately 320.71 μmol/g·h, which is roughly seven times higher than that of the CF/SrTiO3fiber alone. The enhanced photocatalytic activity of the CF/SrTiO3/In2O3fiber can be attributed to the heterojunction structure enriched with oxygen vacancies. It was found that these oxygen vacancies created defective states that served as traps for photogenerated electrons, facilitating their migration to the surface defect states and enabling the reduction of H+in water to produce hydrogen. Furthermore, the synergy between the heterojunction structure and the conductivity of the carbon fiber promoted the generation and migration of photogenerated electrons, reduced the recombination of photogenerated electron–hole pairs, and ultimately improved photocatalytic hydrogen production. This study presents a new approach for designing efficient photocatalysts with surface oxygen vacancies on carbon fibers, providing new insights into the sustainable application of photocatalysts.

Continuous 3D hierarchical construction has been proved to serve as a feasible method to prepare high-efficiency microwave absorption (MA) composites. Herein, an innovative hierarchical carbon fiber (CF)@MXene@ZnO core-sheath synergistic structure with tunable and efficient MA performance has been synthesized via a self-assembly (MXene) and hydrothermal (ZnO) process. Because of increased conductivity loss of the interlayer MXene sheath due to synergistic effects and the enhanced impedance matching of the outer ZnO layer, the optimal reflection loss (RL) value of CMZ2 is −67.35 GHz at 9.0 GHz at a thickness of 3.5 mm and the optimal effective absorption bandwidth (EAB) is 5.44 GHz, covering the full X band at a thickness of 4.0 mm. Furthermore, the CMZ microrods can be used as energy transformers and molecular heaters due to the synergistic effects of the high photothermal conversion efficiency of MXene, high photocatalytic activity of ZnO, and high thermal conductivity of CF. When used as wearable CMZ/polyurethane (PU) composite coatings , the surface temperature increases rapidly with a healing efficiency of above 91% for mechanical damage. These results provide a new strategy to fabricate wearable materials with effective MA and photothermal properties for designing safe and wearable devices .

Hierarchical structural design has been verified as a feasible strategy to fabricate effective electromagnetic wave (EMW) absorbers, so we designed hierarchical core–sheath composites with magnetic particles and dielectric layers. In this work, a hierarchical structure of carbon fiber (CF)@Fe3O4@MoS2 (CPDF7-M) was prepared by introducing Fe3O4 and depositing MoS2 layers on the surface of fibers. Due to the synergistic effects from the CF@Fe3O4 increasing the conductive and magnetic loss and the outer MoS2 layers improving the impedance matching, the optimal reflection loss (RL) value was −63.1 dB at 2.7 mm and the effective absorption bandwidth (EAB) was 9.1 GHz covering the X and Ku band. Moreover, the EAB values were adjusted with a specific MoS2 loading at different thicknesses, which provided the necessary reference for the construction of efficient and flexible absorbers in the EMW absorption fields.

Novel mesoporous carbon fibers (MCFs) were fabricated through a self-templating strategy and solution growth process. MCF modified glassy carbon electrode (MCF/GCE) was proposed for the direct electrocatalytic and simultaneous determination of four DNA bases (guanine (G), adenine (A), thymine (T) and cytosine (C)) using differential pulse voltammetry (DPV) measurement. The MCF/GCE exhibits satisfactory electrocatalytic activity by significantly enhancing the oxidation peak currents and lowering the oxidation potentials toward the four bases when compared with those on GCE. Especially, MCF greatly accelerates the electron transfer of pyrimidine base, which have high oxidation potentials and slow electron transfer kinetics. Moreover, MCF/GCE realizes the simultaneous determination of four DNA bases with low detection limits, high sensitivity and wide linear range. More important, the proposed electrode was successfully applied in the direct detection of bases in herring sperm DNA sample with satisfactory results. Besides, the MCF/GCE shows good long-term stability and reproducibility. These superior performances of MCF/GCE toward purine and pyrimidine DNA bases provide a good possibility for applying the MCF/GCE in our further DNA biosensor research.

The anodic degradation process of carbon fibres (CFs) in carbon-fibre-reinforced-polymer (CFRP) composites was first examined under varying operating currents, particularly in the pore solution of seawater and sea sand concrete. A range of analytical techniques were employed to provide insights into the formation and characteristics of the decomposition products generated in the electrolyte and precipitate. The electrochemical reactions of anions and carbon occurred under the different potential significantly influence the corrosion behaviour of CFRP. The production of diverse forms and quantities of carbon oxides primarily arises from the oxidative deterioration of CFs' graphitic structure. These results reveal the anodic degradation behaviour of CFs, which contributes to the anodic degradation mechanism of CFRP materials, especially when exposed to different current levels in high-chloride and high-alkaline conditions.
