Recently, China's DK Electromagnetic Protection Material Technology Group and SXMX Graphene Technology Company have jointly researched graphene electromagnetic shielding coatings and its engineering application technology to apply graphene electromagnetic shielding coatings to shielding projects for the first time in China, and completed graphene Electromagnetic shielding paint shields and protects the construction of the sample room, the shielding effectiveness reaches 40dB, and the electromagnetic wave can be blocked by 99.99%. Graphene is a honeycomb two-dimensional nanomaterial composed of carbon six-membered rings. The freely movable electrons contributed by sp2 hybrid carbon atoms endow graphene with excellent electrical and thermal conductivity, and it has a wide range of applications in the field of electromagnetic shielding. value. Graphene electromagnetic shielding coatings do not contain metal elements, and have the characteristics of small specific gravity (~0.36g/cm3), good corrosion resistance, high stability, and low cost. Graphene shielding paint is different from the traditional steel structure hexahedral shielding structure. After comprehensive electromagnetic protection design in a conventional room, the shielding paint is coated on the wall surface, combined with other electromagnetic protection products, and electromagnetic protection means can achieve 40dB The above shielding effect. Graphene shielding coating has simple construction technology and high utilization rate of housing area. Compared with traditional steel structure, it has significant advantages and has broad prospects.
