“…), plasma treatment, surface coating, chemical grafting, chemical vapor deposition, and multi-scale enhancement. 15–17 Among them, the surface coating method represented by the sizing technology has gained wide attention in recent years due to its strong operability and being possible to use in continuous industrial production. However, commercial CFs are mostly matched with thermosets such as epoxy resins, causing the sizing agent easy to decompose and fail at the high processing temperature of thermoplastics, even giving rising to defects and damaging the interfacial bonding.…”

In the field of interfacial enhancement of composite, sizing method has attracted extensive attention. In this research, a new complex emulsion type sizing agent containing polyetherimide (PEI) and covalently chemical functionalized graphene oxide (GO) was first proposed to further improve the interfacial adhesion of carbon fiber (CF)/PEI composites, adapt to the high processing temperature, and overcome the shortcomings of the solution type sizing agent. The emulsion was prepared by the emulsion/solvent evaporation method. In order to avoid the agglomeration of nanomaterials on CF surface, the monomer and polymer structure of PEI was used to functionalize GO, so as to achieve better compatibility and dispersion of GO in PEI. The physicochemical state of CF surface was characterized and the successful introduction of GO was verified. The microbond test revealed that the introduction of GO further improved the IFSS compared with only PEI sizing. When GO grafted with PEI was used as the main component of the sizing agent, the IFSS reached the largest with an increasement of 55.96%. The mechanism of interfacial reinforcement was proposed. Increased ability of mechanical interlocking, the mutual solubility between PEI molecular chains, and the improvement in wettability may be beneficial to the interfacial strength. This mild and effective modification method provided theoretical guidance for the interfacial enhancement of composites and was expected to be applied in industrial production.

“…[27][28][29] It can be seen that the application of carbon severely relies on its compositing capability with other materials. However, pristine carbonaceous materials are usually fabricated via hightemperature pyrolysis in an inert gas atmosphere, [30][31][32][33] which makes the surface of carbon extremely hydrophobic, hindering their application in numerous elds. For example, in the aerospace eld, carbon ber must be composited with other resins via interactions between active functional groups on the surface.…”

“…Electrophoretic deposition (EPD) is one of the most popular and promising methods for the preparation of different nanostructured surfaces and devices [1,2], especially carbon nanotube (CNT)-reinforced fibers [3][4][5]. It was shown [6] that the ultrasonically assisted (i.e., ultrasound is applied throughout the deposition process) EPD of CNTs and nanotube forests [7] on carbon fibers (CFs) or on glass [8][9][10] improved the mechanical properties, interfacial shear strength, and friction resistance [11] of the final fibrous hierarchical composites.…”

It is well known that carbon nanotube (CNT) oxidation (usually with concentrated HNO3) is a major step before the electrophoretic deposition (EPD). However, the recent discovery of the “onion effect” proves that multiwalled carbon nanotubes are not only oxidized, but a simultaneous unsheathing process occurs. We present the first report concerning the influence of unsheathing on the properties of the thus-formed CNT surface layer. In our study we examine how the process of gradual oxidation/unsheathing of a series of multiwalled carbon nanotubes (MWCNTs) influences the morphology of the surface formed via EPD. Taking a series of well-characterized and gradually oxidized/unsheathing Nanocyl™ MWCNTs and performing EPD on a carbon fiber surface, we analyzed the morphology and wettability of the CNT surfaces. Our results show that the water contact angle could be gradually changed in a wide range (125–163°) and the major property determining its value was the diameter of aggregates formed before the deposition process in the solvent. Based on the obtained results we determined the parameters having a crucial influence on the morphology of created layers. Our results shed new light on the deposition mechanism and enable the preparation of surfaces with steerable roughness and wettability.
