1. Introduction
Excellent tensile strength, high stiffness, light weight and great thermal resistance make carbon fiber reinforced composites an ideal structural material [1]. However, due to the smooth and chemically inert carbon fiber surfaces, the carbon fiber reinforced composites show a weak interfacial shear strength because of the poor wettability and adsorption between carbon fiber and matrix [2]. In the past decades, people have developed a lot of technologies to improve the interfacial properties of carbon fiber composites. Generally, surface modification of carbon fiber could be the favorite routine [3]. Recently, it is found that graphene can be used as the reinforcing phase in polymer composites because of its stress transfer behavior between the polymer matrix and carbon fiber [4e9]. Up to now, many methods have been developed to introduce GO onto the surface of carbon fibers, including coating [10], chemical grafting [11e13], chemical vapor deposition [14], supercritical [15] and solvothermal treatment [16]. However, the improvement of interfacial properties is often followed by a sacri- fice of fiber tensile strength owing to the etching effect during the treatment. Therefore, it is meaningful to develop the technology to enhance both the tensile strength of carbon fiber and the interfacial properties of its composites. Recently, electrophoretic deposition (EPD) is used to deposit carbon nanotubes and GO on carbon fibers. And it is found that EPD show no weakness on the tensile strength of carbon fiber [17e19]. Nevertheless, the GO layers coated on the carbon fiber show poor dispersibility [20], and they take a long time as 30 min to finish the deposition, which make it not suitable for continuous production of high-performance carbon fiber. In this study, we proposed an efficient EPD method to deposit GO onto the surface of carbon fiber in a mild condition. Different from the previous studies [21,22], isopropyl alcohol, instead of water, was used as the electrolytic solution to avoid generation of big bubbles, which increased the dispersibility of GO on the surface of carbon fiber and the deposition efficiency. This new technology decreased the deposition time of GO to 1 min. Meanwhile, the tensile strength of carbon fiber was increased from 4.54 GPa to 6.11 GPa while the IFSS of carbon fiber/epoxy composites were enhanced from 46.8 MPa to 79.5 MPa.
