“…The chemical analysis of the Ox shows an increase in the peaks assigned to CO, C=O and COOH (Figure 2), corroborating the formation of the aforementioned functional groups on the surface of the fiber, due to the fiber oxidation, and explains the significant increase in oxygen in the sample. Furthermore, from the XPS high-resolution C 1s , the spectrum of the Ox-Si fiber, evidenced the appearance of a new peak at around 283.3 eV, which has been assigned to the C-Si bond [3,29,31], corroborating the presence of the silane on the sample. In addition, growth of the 286.6 eV peak is observed, which could be due to the presence of the Si-O-C bond and/or to the epoxide groups of the silane structure [3,9,32].…”

The formation of the Si-O-C covalent bond appears to be generated from the reaction and subsequent condensation between the silane and the carboxylic acid groups (Figure 3), due to a decrease in the COOH peak and an increase in the C=O, with respect to the Ox fiber.…”

“…In addition, for the Ox-Si and Ox-Pre fibers, 3.80 and 3.62% silicon (Si) was found, respectively, confirming the presence of the silane on the fiber surface. From the deconvolution of peak C 1s (Figure 2), it was possible to identify five main peaks: the sp 2 hybridization or carbon-carbon double bond (C=C), the carbon-carbon single bond (C-C), hydroxyl groups (CO), carbonyl groups (C=O) and carboxylic acids (COOH) [2,3,29,30]. The binding energy and the atomic percentage (with respect to the amount of carbon in each sample) of each of the peaks are presented in Table 2.…”

“…However, in some cases, their application has been limited because of limited fiber-matrix adhesion, as reported in several technical papers, thus encouraging to improve its performance for more demanding technological applications [3][4][5][6]. In a fiber-reinforced composite, the applied load is transferred from the matrix to the fiber through shear stresses and if the IFSS is low, lower loads can be transferred to the fiber, thus resulting in a low efficiency composite material [6,7].…”

“…It is known that effective mechanical properties of a composite depend on the properties of each of the constituents, and most importantly, on the quality of the fiber-matrix interfacial region, which is based on the interactions between the molecular structures present in the interphase [1][2][3]. However, in some cases, their application has been limited because of limited fiber-matrix adhesion, as reported in several technical papers, thus encouraging to improve its performance for more demanding technological applications [3][4][5][6].…”

Abstract. Multiwall carbon nanotubes (MWCNTs) previously treated with a cationic polymer were incorporated on the surface of carbon fibers modified by three different chemical treatments, namely, oxidation, oxidation-silanization and oxidation-pre-impregnation. Prior to the incorporation of the MWCNTs, the physical surface properties of the fibers were studied by contact angle and the chemical surface properties by X-ray photoelectron spectroscopy (XPS). The interfacial shear strength (IFSS) of the different systems carbon fiber-MWCNTs-matrix was evaluated using the single-fiber fragmentation test (SFFT) and it was observed that the IFSS of the oxidized-pre-impregnated fibers, was considerably higher than that observed for the other fiber-matrix systems. This was attributed to enhanced interfacial interactions because the fiber surface treatments improved the wettability of the carbon fiber and the MWCNTs, which resulted in a better fiber-matrix mechanical interlocking and to the formation of covalent bonds between the different phases of the composite.

Carbon Nanofibers Grown on Carbon Felt as a Reinforced Current Collector for High‐Performance Lithium−Sulfur Batteries

et al. 2018

View full text Add to dashboard Cite

Lithium−sulfur (Li−S) batteries have attracted much attention, owing to their high theoretical energy density. Many studies have focused on improving areal sulfur loading by using carbonaceous current collectors. However, low sulfur utilization and polysulfide diffusion could be more severe. Herein, we introduce a reinforced current collector consisting of carbon felt (CF) decorated with carbon nanofibers (CNFs), prepared by using chemical vapor deposition (CVD). The CF@CNFs skeleton shows a large specific surface area for well‐dispersed active materials, highly conductive network with faster electronic/ionic transport, and a micro‐/mesoporous structure for spatial confinement on polysulfides. As a result, the cells with CF@CNFs current collectors exhibit a high specific capacity, superior cycling stability, and a good rate capacity. This work will provide a promising choice for designing novel current collectors toward high‐performance, high sulfur‐loading Li−S batteries.

Carbon fiber reinforced composites have attracted lots of attention in many fields. However, on account of the poor infiltration of resin to carbon fiber, the weak interface performance between fiber and resin has been restricting the interface properties of composites. In recent progress, the review attaches more importance to the introduction of the third phase monomer, which mainly uses physical and chemical methods to assemble nanomaterials (such as carbon nanotubes, graphene, etc.) on the carbon fiber surface to modify the interface structure of the carbon fiber reinforced composites, and all of them have been demonstrated in this paper. Furthermore, the effects of introducing nanomaterials on the structure of the fiber/resin interface and the relationship between multi‐scale interface structure and properties have been investigated. It can be seen that the design idea of researchers mainly uses one or more theories to improve the interface properties of carbon fiber reinforced composites, such as transition layer, chemical bonding, mechanical interlocking, infiltration, diffusion, and adsorption. In brief, this work provides some novel insights for the preparation of carbon fiber reinforced composites with excellent interlaminar shear strength.
