The Marine Chemical Institute has made a stage progress in the research of graphene coatings

Graphene is the hottest "star" in the materials industry in recent years and has been hailed as the "King of New Materials" by the industry. Since 2014, the Institute has carried out research on the application of graphene in coatings, and has made good progress and achieved a series of phased results, especially in the field of anti-corrosion coatings, electromagnetic wave coatings and other functional coatings.
Graphene is a two-dimensional sheet of material made of carbon atoms, which is stripped from graphite and consists of only one layer of atomic thickness, which is about one-hundredth the thickness of a hair, but its fracture strength is 200 times higher than that of the best steel, and its tensile range can reach 20% of its size, making it the thinnest and hardest nanomaterial known in the world. The physical and chemical properties such as super-high surface area, excellent conductivity, super-high strength, toughness and shielding make it possible to play a prominent role in the fields of conductive coatings and metal anti-corrosion coatings, and take the lead in industrialization.Haihua Institute has cooperated with a number of enterprises and institutions specializing in graphene research to carry out anti-corrosion coatings, water-based coatings, wind-electric coatings, anti-slip coatings and other applications, and made a number of key technological progress., the laboratory research of graphene heavy anti-corrosion coatings in the Marine Chemical Institute has achieved a technological breakthrough. According to the experts of the task force, the coating added graphene is thinner, anti-corrosion and weather resistance is greatly improved, including graphene anti-corrosion coatings used to replace zinc-rich primers, in the key indicators of salt spray resistance time, than the national standard product indicators at least doubled, and the proportion is lower than the ring 70% of the oxygen-rich zinc primer, this kind of products in the field of marine, marine engineering and aviation has broad application prospects, the use of graphene's excellent conductivity and transmission, the introduction of graphene electromagnetic wave coating has also solved some technical problems, can basically meet the customer's demanding needs, into the application verification stage.it is understood that Although China as a large graphite resource country on graphene research started relatively late, but the rapid development, the overall close to the advanced level of foreign countries, in some areas leading and master the independent intellectual property rights. At the World Mobile Congress held in Shanghai on June 29, the graphene pavilion was the highlight of the conference, which received the attention of CCTV, Science and Technology Daily and Hong Kong Dagong. The graphene heavy anti-corrosion coating developed by the Marine Chemical Institute was unveiled at the exhibition, and the real model of products and corrosion inspection attracted great interest from the media, institutional investors and professional audiences, and was affirmed by industry experts.data show that the current cost of graphene processing in China has dropped to one-tenth of 2011, excellent rate and consistency has also been greatly improved, downstream applications in large-scale release. "Made in China 2025" clearly defines the key position of graphene in China's strategic cutting-edge materials, and in November 2015, the United Nations Development and Reform Commission of the Ministry of Industry and Information Technology and the Ministry of Science and Technology issued "Several Opinions on Accelerating the Innovation and Development of Graphene Industry" also pointed out that the stone Ene materials in China is in a critical period from laboratory to industrialization, to make graphene industry into a pilot industry, and gradually realize the material in some industrial products and consumer goods on the industrialization of the application, to 2020, the formation of a sound graphene industry system.Keeping up with market developments and seizing the opportunity of policy support, THESC will continue to conduct in-depth application research in the fields of anti-corrosion and other functional coatings, as well as water-based coatings and solvent-free coatings, on the basis of the experimental results already achieved, and at the same time, in cooperation with professional scientific research institutions engaged in basic research, conduct research on the corrosion-proof mechanism of graphene coatings, and make use of the advantages of the company's applied research to achieve strong joint efforts to further broaden its application in the field of coatings and seek theoretical basis for improving the industrial system.
