“…Grafting of CNTs onto CFs could also be achieved by chemical reaction between the pre-modified functional groups on the surfaces of both CNTs and CFs [7,8]. The electrophoresis technique could be used [9][10][11], where CNTs were uniformly deposited on the surface of carbon fiber fabric from the CNT dispersion in an applied electric field.…”

“…3, the ox-MWCNTs with the COOH groups still remain enough negative charge at pH 3 (zeta potential -15 mV). In our case, it can be explained that the increase in roughness at lower pH is due to the increased positive charge of GF-NH 2 and the Comparing with other deposition methods of CNTmodified fibers by EPD [27,28] or sizing agent [23], the surface morphologies we obtained were much more compact and uniform. The result may be attributed to the stable dispersion of ox-MWCNTs solution and the strong electrostatic interaction under certain assembly pH.…”

Glass fiber-multiwall carbon nanotubes (GFMWCNTs) hybrid preforms were prepared by electrostatic assembly method. Negatively charged MWCNTs by oxidization treatment were directly adsorbed onto the surfaces of positively charged GF to form tunable structure. The thickness and morphology of GF-MWCNTs preforms can be controlled by the assembly pH value and the concentration of oxidized-MWCNTs solution. We demonstrate that GF-MWCNTs preforms have uniform and porous interconnected network structure of MWCNTs on the surfaces of GF using FESEM. The multi-scale composites with the hybrid preforms were prepared by melt compounding. The presence of MWCNTs with porous nanostructure helps in the formation of interpenetrating network with polyamide 6 (PA 6) at the interface layer. As a result, the tensile tests of these multi-scale composites exhibit higher tensile properties in comparison with composites with GF, showing a promising structural composite to replace the traditional GF-reinforced composites with limited improvement of the performance.

“…It has been demonstrated that the ability of the deposition of CNTs onto the CF surface enhances the interfacial properties. As a result, a variety of surface treatments of CF have been utilized to incorporate CNTs onto the surface of CF such as sizing agents containing CNTs, [17,18] chemical grafting, [19,20] electrophoretic deposition [21,22], and chemical vapor deposition (CVD). [23,24] Among these methods, sizing agents containing CNTs show obvious advantages for practical applications such as simplicity and flexibility.…”

2015)Interfacial improvement of carbon fiber-reinforced methylphenylsilicone resin composites with sizing agent containing functionalized carbon nanotubes, A liquid sizing agent containing multiwall carbon nanotubes (MWCNTs) was prepared for carbon fiber (CF) reinforced methylphenylsilicone resin (MPSR) composite applications. In order to improve the dispersion of MWCNTs in the sizing agent and interfacial adhesion between CF and MPSR, MWCNTs and CF were functioned by the chemical modification with tetraethylenepentamine (TEPA) used as a MPSR curing agents. The CF before and after the sizing treatmentreinforced MPSR composites were prepared by a compression molding method. The microstructures, interfacial properties, and impact toughness of CF were systematically investigated. Experimental results revealed that a thin layer of MPSR coating containing functionalized MWCNTs (MWCNT-TEPA) was uniformly grafted onto the surface of CF. The sized CF-reinforced MPSR composite showed simultaneously remarkable enhancement in the interlaminar shear strength and impact toughness. Meanwhile, the tensile strength of CF had no obvious decrease after sizing treatment. In addition, the interfacial reinforcing and toughening mechanisms were also discussed. We believe that the facile and effective method in preparing multifunctional fibers provides a novel interface design strategy of carbon fiber composites for different applications.
