“…Nowadays, with the increasing application of batteries used in humid working environments, for instance, offshore wind energy harvesting, water infiltration through cracks in the outer metal packing, and even catastrophic accidents caused by corrosion cannot be ignored. Many measures, including cathode protection technology [ 1 , 2 , 3 ], the design of novel anticorrosive materials [ 4 , 5 ], and multifunctional anticorrosion coatings [ 6 , 7 ] have been used in metal materials. Among these strategies, multifunctional anticorrosion coatings have been widely used owing to their wide selectivity and applicability, excellent physical barrier performance, stable chemical properties, and low-cost [ 6 , 8 , 9 ].…”

A waterborne epoxy coating with superior corrosion resistance was developed by using a novel amino-functionalized graphene oxide (GO) that was modified by 2,5-diaminobenzenesulfonic acid. A battery of characterization methods, such as Fourier transform infrared spectroscopy (FT-IR), Raman spectra, X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM), was used to prove that DGO was successfully prepared by grafting the amino of 2,5-diaminobenzenesulfonic on GO. The results indicated that the surface of DGO became rougher than GO, but a complete sheet structure was still maintained after modification; the optimal modified GO could be achieved when the mass ratio of 2,5-diaminobenzenesulfonic acid and GO was 5:1. The electrochemical impedance spectroscopy (EIS) tests indicated that the impedance at 0.01 Hz of a coating with 0.2 wt.% DGO still remained at a relatively high value after immersion for 48 h in 3.5 wt.% NaCl, which was about one order higher than a pure waterborne epoxy resin coating, and the corrosion current density decreased from 3.76 × 10−11 A/cm2 to 3.62 × 10−12 A/cm2. The dry adhesion and wet adhesion increased to 1.90 and 1.22 MPa, respectively, and the adhesion loss decreased from 53% to 36%. These interesting features could make waterborne epoxy coatings a promising anticorrosion coating for metal in long-term protection.

“…The thermally expanded graphite (the TEG) has a number of unique properties. The extended zone of structural compactability is typical for the TEG powders, i.e., they are formed in a wide range of densities during pressure treatment [1,2].…”

The paper presents the results of research of compactability processes of thermally expanded graphite powders during rolling. The thermally expanded graphite powders can be used to obtain highly porous and high-density products having different geometric parameters. The rolling method is used to produce long-length products. Strips production of the thermally expanded graphite with a particular thickness, density and physical-mechanical properties can be achieved by controlling the rolling conditions. When implementing the rolling process it is necessary to use plates due to high adhesion of powder to the rolls of the rolling mill. The usage of plates has allowed to develop the technology for the production of single and multilayer strips and evaluate its effectiveness.
