“…Recently, many researchers have made considerable efforts to graft the surface of CFs with various active nanoparticles to change interfacial microstructure and properties of composites [13,14,15,16]. Gao [17] prepared a new hierarchical reinforcement containing octaglycidyldimethylsilyl polyhedral oligomeric silsesquioxane (POSS) and CFs with the remarkable improvement in interfacial strength of composites.…”

The quality of interphase in carbon fibers (CFs) composites makes a key contribution to overall performance of composites. Here, we achieved for the first time the chemical grafting of halloysite nanotubes (HNTs) with amino or carboxyl groups onto the CFs surface aiming to increase composites interfacial strength. HNTs were grafted using 3-aminopropyltriethoxysilane (APS) followed by succinic anhydride treatment, and HNTs with amino groups (HNT–NH2) or carboxyl groups (HNT–COOH) were separately introduced into the interphase of composites. Functional groups of HNTs and fiber surface structures were characterized, which confirmed the modification success. The wettability between the modified CFs and resin have been enhanced obviously based on the improved fiber polarity and enhanced surface roughness by the introduced two functionalized HNTs with the uniform distributions onto fiber surface. Moreover, interfacial properties and anti-hydrothermal aging behaviors of modified methylphenylsilicone resin (MPSR) composites were improved significantly, especially for HNT–COOH grafting. In addition, the interfacial reinforcement mechanisms for untreated and modified CF composites are discussed and compared.

“…In recent studies, CFs modified using nanoscale materials for notably improving interfacial wettability and adhesion with matrix resin have attracted increasing attention and have become more popular [20,21,22,23]. Noteworthy, nano-sized SiO 2 with the unique spherical structure and high physicochemical properties has been smartly utilized for surface modification of CFs with the aim of constructing multi-scale and hierarchical structures [24,25,26]. Typically, the uniform dispersion and tight binding of nano-sized SiO 2 onto CF surfaces has been considered as a vital factor for obtaining a high interfacial strength as well as their wide application.…”

In the present research, to enhance interfacial wettability and adhesion between carbon fibers (CFs) and matrix resin, hydrophilic silica nanoparticles (SiO2) were utilized to graft the surface of CFs. Polydopamine (PDA) as a “bio-glue” was architecturally built between SiO2 and CFs to obtain a strong adhesion strength and homogenous SiO2 distribution onto the surface of CFs. The facile modification strategy was designed by self-polymerization of dopamine followed by the hydrolysis of tetraethoxysilane (TEOS) onto carbon fibers. Surface microstructures and interfacial properties of CFs, before and after modification, were systematically investigated. The tight and homogeneous coverage of SiO2 layers onto the CF surface, with the assistance of a PDA layer by self-polymerization of dopamine, significantly enhanced fiber surface roughness and wettability, resulting in an obvious improvement of mechanical interlocking and interfacial interactions between CFs and matrix resin. The interlaminar shear strength (ILSS) and the interfacial shear strength (IFSS) of CF/PDA/SiO2 reinforced composites exhibited 57.28% and 41.84% enhancements compared with those of untreated composites. In addition, impact strength and the hydrothermal aging resistance of the resulting composites showed great improvements after modification. The possible reinforcing mechanisms during the modification process have been discussed. This novel strategy of developed SiO2-modified CFs has interesting potential for interfacial improvements for advanced polymer composites.

“…The properties of composites are influenced not only by the inherent characteristics of CFs and matrix resin but also by the quality of their interface . However, the good wettability and desired interfacial adhesion cannot obtain owing to the nonpolar, stable and smooth graphite surface of Untreated CFs without fiber surface modification …”

New hybrid carbon fibers (CFs) were facilely prepared via in situ synthesizing hyperbranched polysiloxane with epoxy groups onto the fiber surface with the aim to enhance interfacial strength of composites. CFs were grafted with phenyl amine groups through an aryl diazonium reaction, and then modified with hyperbranched polysiloxane obtained by the sol-gel polymerization of γ-glycidyloxypropyltrimethoxysilane. Surface structures of different CFs were characterized by Raman spectroscopy and X-ray photoelectron spectroscopy, indicating the successful modification. The introduced hyperbranched polysiloxane enhanced fiber roughness, polarity, wettability, and surface free energy. Hence, the interfacial shear strength and impact toughness of polysiloxane modified composites (CF-g-Polysiloxane) increased sharply compared with those of untreated composites. Moreover, Interfacial reinforcing and toughening mechanisms have also been studied, and polysiloxane modification maintained fiber tensile strength. The obvious improvement of anti-hydrothermal aging behaviors after modification could be due to the introduction of strong Si O Si bonds at the interface.
