“…The characteristic absorption peaks at 1722, 1230, 1048, and 913 cm −1 belong to C=O, C-O, C-O-C, and -CH(O)CH-, respectively [20,28,29], indicating the presence of a large number of oxygen-containing groups on the surface of f-GO. In the infrared spectra of GO-Ti, new peaks appear at 1540, 799, and 1439 cm −1 , corresponding to the secondary amide N-H-bending, N-H rocking, and C-N stretching [30], respectively, and the -CH(O)CH-absorption peak at 913 cm −1 disappears, which proves that the epoxy group of f-GO reacts with the amino group of f-Ti [31]. This conclusion is further proved in the subsequent XPS test.…”

Graphene oxide–titanium (GO-Ti) composite materials were fabricated using GO as a precursor and then anchoring nano titanium (Nano-Ti) particles on GO sheets with the help of a silane coupling agent. Then, the coating samples were prepared by dispersing GO, Nano-Ti particles, and GO-Ti in an epoxy resin at a low weight fraction of 1 wt %. The GO-Ti composites were investigated by X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The dispersibility and anti-corrosion mechanism of the coatings were studied by sedimentation experiments, electrochemical impedance spectroscopy (EIS), SEM, and salt spray tests. The mechanical properties of the coatings were analyzed by friction and wear tests. The results showed that the Nano-Ti particles were successfully loaded on the GO surface by chemical bonds, which made GO-Ti composites exhibit better dispersibility in the epoxy than GO. Compared with Nano-Ti particles and GO, the GO-Ti composite exhibited significant advantages in improving the corrosion resistance of epoxy coatings at the same contents, which was attributed to the excellent dispersibility, inherent corrosion resistance, and sheet structure. Among the different proportions of composite materials, the GO-Ti (2:1) material exhibited the best dispersibility and corrosion resistance. In addition, the composite material also greatly improved the wear resistance of the coating.

“…Among these, epoxy resins that are a class of significant thermosetting polymers have received much attention. They have been widely used as matrices for creating high‐performance surface composite coating because of their high modulus, excellent adhesion properties, chemical resistance, etc . However, the inherent brittleness, poor impact resistance, and temperature resistant performance extremely limited their applications in industrial fields.…”

In this work, we reported the synergistic effect of functional carbon nanotubes (CNTs) and graphene oxide (GO) on the anticorrosion performance of epoxy coating. For this purpose, the GO and CNTs were firstly modified by the 3aminophenoxyphthalonitrile to realize the nitrile functionalized graphene oxides (GO-CN) and carbon nanotubes (CNTs-CN). As modified GO-CN and CNTs-CN were characterized and confirmed by Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, and gravimetric analyzer. It was found that about 19 and 24 wt% of 3-aminophenoxyphthalonitrile were grafted onto the surface of the GO and CNTs, respectively. The electrochemical impedance spectroscopy results showed that the GO-CN&CNTs-CN hybrid materials exhibit a remarkable superiority in enhancing the anticorrosion performance of epoxy coatings. Significant synergistic effect of the lamellar structural GO-CN and CNTs-CN on the anticorrosion performance of epoxy composite coatings was designed. Besides, the epoxy coating with 1 wt% of the GO-CN&CNTs-CN hybrid exhibited the best anticorrosion performance, in which the impedance showed the largest one (immersion in 3.5 wt% of NaCl solution for 168 hr).

Photocathodic protection coatings have been widely applied in various areas such as ship and architectural protection, or chemical industry. In this work, a composite of titanium dioxide loaded with reduced graphene oxide (RGO/TiO2) was prepared and used as filler on waterborne polyacrylate (PA) coating to reinforce the metal protection against corrosion. Compared with the current filler of zinc phosphate used for anticorrosive coating, the photoelectrochemical properties of RGO/TiO2‐PA coating exhibit improved photocathodic protection under visible light illumination since RGO/TiO2 composite has significant superiority in enhancing metal protection due to its dispersion, micropore blocking ability, and photoelectrochemical conversion performance. The mechanism of anticorrosion reinforcement of RGO/TiO2‐PA coating was hypothesized that graphene provides an extrabarrier layer to obstruct corrosive in dark condition and photocathodic protection under lighting. © 2019 Wiley Periodicals, Inc.
