"The graphene electromagnetic shielding film produced by the team has passed the certification of the Northwest Institute of Nuclear Technology of China and can be used in the fields of aerospace and nuclear technology."
Recently, on the production line of the WHHX Graphene Technology Corporation's graphene film precision coating line, barrels of high-purity graphene oxide slurry have undergone 4 processes to become a piece of graphene electromagnetic shielding film material.
"According to the current level of technology and industrialization, it is difficult to exfoliate graphene with a single-layer structure on a large scale, and it can only be prepared in a small amount in the laboratory." Dr. Hu, CTO of WHHX, introduced that traditional graphene is in powder form, and WHHX It was processed into graphene films, each containing 100,000 layers of graphene. Due to the use of a unique doping process, the graphene film has the characteristics of high thermal conductivity, high electrical conductivity, ultra-flexibility, and self-support.
Different from the metal materials and graphene composite materials used in the electromagnetic shielding layer of cables on the market, the graphene film material developed by WHHX not only has a wider frequency range of shielding, but also reduces the volume of the cable by more than 50%. According to Dr. Hu, the full-band shielding efficiency of the material reaches 80dB, which can achieve 99.999999% electromagnetic wave blocking. "In the application field of cable electromagnetic shielding layer, the graphene film material developed by WHHX has strong anti-electromagnetic interference ability and global leading comprehensive performance."
"Behind the technical advantages is the accumulation and precipitation of the R&D team for 10 years. WHHX has carried out a thorough research on the internal core structure characteristics and preparation process of graphene materials." Dr. Hu introduced that in 2008, the R&D team of Professor He of Wuhan University of Technology was founded. the enterprise. Relying on Wuhan University of Technology and Hubei Provincial Radio Frequency and Microwave Technology Research Center, WHHX has built a research and development platform to gather high-end talent teams and cutting-edge technology projects in the field of graphene technology at home and abroad.
"The company continues to expand the application fields of graphene film materials, and has reached cooperation with a number of manufacturers in the direction of electrical conductivity and thermal conductivity to apply graphene film materials to electromagnetic shielding, graphene antennas, high-power radar, 3C electronic terminal products and other scenarios." Dr. Hu introduced that in order to increase production capacity, in addition to the R&D workshop in Wuhan, WHHX has also established a production base in Ah, with a production scale of 600,000 square meters per year (calculated on a thickness of 25 microns).
