36Kr learned that recently, Guangdong Murray Technology Co., Ltd. (hereinafter referred to as "Murray Technology") announced the completion of more than 100 million yuan of B round financing, two rounds of financing led by Chendao Capital exclusive investment and Yuexiu Industry Fund, by Potential Energy Capital as the exclusive financial adviser for several consecutive rounds. Zhao Hongzhong, CEO of Murray Technology, said that this round of financing funds will be used for production line construction, product research and development and business development.
Murray Technology
Founded in 2015, Murray Technology is a high-tech new materials company specializing in the application and development of advanced materials such as graphene. Murray Technology has a graphene research team with a number of national high-level talents as the core, and currently has mastered a variety of graphene preparation technologies and laid out international patents.
Murray Technology's products include graphene materials, thermal management application products (graphene thermal conductive film, graphene thermal equalizer plate, graphene thermal silicide, graphene thermal conductive phase change material, etc.), graphene micro-nano cavity superconducting film, graphene new energy conductive materials, etc.
At present, the graphene industry in the mainland is in a stage of rapid development, according to relevant data, as of January 2021, there are 17,000 graphene-related enterprises in the mainland, and it is still growing.
As far as graphene itself is concerned, since 2017, graphene has had some application practices in lithium batteries, solar energy, heat dissipation materials, cable LEDs and other industries.
Zhao Hongzhong said that as a new type of material discovered at the beginning of this century, the physical properties of graphene are almost subversive compared to existing materials, which has also evolved a large number of commercial application possibilities. However, after several years of practical exploration, the current application of graphene in the field of 3C electronics and new energy has landed relatively quickly, and upstream companies have gradually shifted their attention from the new application of graphene to the efficient preparation and production of graphene materials and products.
With the heat dissipation demand of 3C electronic products as the main goal, Murray Technology has launched graphene thermal conductive film products, and opened up the whole industry chain technology of upstream graphene raw material production, midstream coating film formation, and downstream heat treatment die-cutting manufacturing, realizing the stable supply of graphene thermal conductive film for electronic products.
Zhao Hongzhong told 36Kr: "Graphene is a new two-dimensional nanomaterial after all, it is easy to appear upstream production of graphene raw materials enterprises do not know the specific application, downstream application manufacturers can not control the specific performance of graphene raw materials, so Murray Technology must have both graphene raw materials and specific products research and development and production capacity." ”
In terms of graphene production, it is mainly divided into physical methods and chemical methods, and physical methods are mainly used in experimental research because they cannot guarantee consistency and high-quality graphene mass production. The theoretical and experimental methods of chemical production of graphene have been relatively mature, and the more conventional chemical methods mainly include Brodie method, Staudenmaier method, Hummers method, etc., which are still being optimized on large-scale mass production.
However, the use of chemical methods to prepare graphene materials requires the use of solvents such as strong acids as a reaction environment, and a large number of acid-containing substances will be generated in the production process, which means that the related graphene production enterprises must have good chemical production and processing capabilities.
Through cooperation with leading chemical enterprises, Murray Technology has developed a complete set of production, reaction and treatment processes, integrating the production of graphene raw materials into the large chemical system, realizing the recycling of production raw materials and tail liquids, reducing production costs, and ensuring the stable supply of products.
Murray Technology product layout
In the midstream coating film formation, downstream heat treatment and die-cutting manufacturing links, Murray Technology has also established corresponding production lines and production bases. Among them, the coating film-forming production line began to be put into production in 2019, and the heat treatment base in Yunnan also provided a guarantee for the mass production of thermal conductive films for electronic products.
At present, Murray Technology graphene thermal conductive film in the weather resistance, heat flux, thermal conductivity and other key indicators of excellent performance, its products have been stably supplied to a number of mainstream manufacturers, and to achieve an annual output of 1 million square meters of supply capacity. On the market side, Murray Technology uses the advantages of its own vertical industry chain to actively dock with end customers, has R&D and mass production layouts in the fields of 5G, new energy batteries and new energy vehicles, and constantly innovates with industry-leading manufacturers to develop industry-leading products.
Zhao Hongzhong said: "At present, most graphene manufacturers on the market will only lay out one or several links in the industrial chain, and it is very rare for Murray Technology to open up the upstream and downstream, which requires more investment in R & D and production talents, as well as a longer construction cycle and relatively heavy asset investment." But we believe that at this stage this is a must, graphene is a new field of materials science, through the upstream, middle and downstream can better help us improve the performance of basic materials, to meet the needs of users. ”
In addition to the application of Murray technology products in the above fields, it is also actively expanding high-end application fields such as aerospace and biomedicine. It is understood that Murray Technology has cooperated with a satellite company, and it is expected that there will be satellite launches equipped with graphene components of Murray Technology this year.
Zhao Hongzhong said that in the next few years, Murray Technology will continue to explore the application field and product form of graphene products, and its own personnel scale will continue to expand.
