Summary: This study experimentally investigated the effects of O-2 plasma pretreatment on the grafting of amino functional groups onto CFs. It was found that the degree of oxidation was positively correlated with the grafting efficiency, and the results depended on the formation of unsaturated C, C-OH, and O=C-OH groups during the oxidation process. The earlier oxidation process can be controlled to regulate the ammonia grafting of CF.

Summary: A mussel inspired co-deposition of ferric ion-polydopamine (PDA) on carbon fiber is developed to enhance the interfacial adhesion of epoxy composites. The effects of ferric ion contents on fiber surface characteristics and interfacial adhesion are investigated. The formation of bis-and tris-Fe3+-catechol complexes is affected by the addition amount of FeCl3, while the level of Fe3+ ions significantly impacts DA oxidation. The surface modification with ferric ion-PDA complex can increase the interfacial shear strength by enhancing the interfacial crosslinking density.

Summary: The study showed that both VDBD and DCSBD plasma sources had similar effects on improving the surface of BOPP film, but VDBD treatment resulted in slightly higher surface roughness and more efficient adhesion. Comparable results were achieved for both plasma sources in terms of enhanced surface wettability, degree of oxidation, and stability of induced changes, with DCSBD having less impact on surface deterioration than VDBD.

Summary: This study investigates the composites of milled carbon fiber and poly(dicyclopentadiene) (pDCPD) - a common and inexpensive ROMP polymer. The results show that the addition of 10% fibers significantly improves the tensile modulus, compressive modulus, and fracture toughness of the material, but also leads to a decrease in tensile and flexural yield strength. The increase in modulus follows the rule of mixtures for randomly distributed fibers, despite the presence of local anisotropy due to stress applied during sample fabrication.

Summary: Lignin obtained from wood is an abundant and renewable carbon resource for energy storage, but its unfavorable processing conditions and limited performance hinder its use as supercapacitor electrodes. In this study, plasma treatment was used to enhance the electrochemical performance of lignin-based carbon fibers. The treatment increased the electrode's capacitance by 20% and improved its rate capability and energy-power performance. The introduction of desirable functional groups through plasma treatment also enhanced the long-term cycling stability and self-discharge characteristics of the device. Investigation was also conducted on the effects of different oxygen surface functional groups on the capacitive performance of the fibers under different conditions.

Summary: A core-shell ZrO2@GO hybrid was prepared and incorporated onto carbon fiber via dip-coating to enhance the interfacial adhesion of epoxy composites. The ZrO2@GO functionalized fiber composite showed the highest interfacial shear strength, with significant improvements over untreated fiber, only epoxy sizing coated fiber, and silane coupling agent-encapsulated ZrO2 decorated fiber composites. The enhanced adhesion was attributed to improved resin wettability, multiple interactions between GO and epoxy resin, and the formation of a mobile network absorbing energy.

Summary: In this study, porous graphene oxide was used as a nanoscale reinforcement to improve the interfacial adhesion in composites, resulting in significantly higher interfacial shear strength compared to untreated fiber and GO/fiber reinforcement. The enhancement was attributed to rich interfacial interactions and improved surface energy through the synergistic effects of polyethylenimine, as well as the formation of a rigid-soft transition zone for stress dissipation. The advantages of porous graphene oxide suggest potential for further advancements in composite materials by carefully designing its properties.

Summary: A series of small molecules containing alkenes were electrografted onto carbon fibers surface using in situ generation of aryldiazonium salts. This surface modification approach utilizing ROMP showed significant increases in interfacial shear strength (IFSS) of up to 189%. Dilution of strained norbornene alkenes at different ratios still resulted in improved IFSS gains compared to pristine fibers, demonstrating the potential of ROMP for tailoring the surface chemistry of carbon fibers for advanced composites.

Summary: This study investigates the effects of hygrothermal ageing and atmospheric plasma surface treatment on a 3D carbon/epoxy-amine woven composite material. The results show that hygrothermal ageing leads to irreversible absorption behavior and modifies the surface chemistry and topology, while atmospheric plasma treatment causes oxidation of the matrix but also removes the adsorbed humidity.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: In this study, a potential platform to enhance Raman scattering and increase the number of observable Raman modes in monolayer transition metal dichalcogenides (TMDs) was proposed. The platform consisted of large-scale arrays of gold micropillars (MPs), which were able to enhance the Raman intensity of TMDs and make difficult-to-detect Raman modes observable. The platform showed great industrial advantages and wide applicability due to its low cost, simple process, large controllable area, and short process time.
