Morion Nanotech brought a new revolutionary product, graphene micro-nano cavity thermal conductive film, to the first appearance at the Xiaomi product launch conference held on August 14, 2023. This graphene micro-nano cavity thermal conductive film has injected new vitality into the thermal management solution of Redmi K60 Extreme mobile phone. The graphene micro-nano cavity thermal conductive film covers the entire screen IC area of the mobile phone, which has the three functions of heat dissipation, caulking and buffering, and the temperature of the core hot zone drops by 2.5°C. This innovative form of heat dissipation has created a broad application prospect for the field of heat dissipation.

The graphene micro-nano cavity thermal conductive film uses graphene as the matrix material to finely manufacture micro/nano-level pores to form a unique micro-nano cavity structure. Its porous and fluffy nature gives excellent cushioning properties. The product exhibits excellent compression resilience, with a rebound stress of only 0.017MPa at a compression of 80%. This product is used for the first time in the mobile phone, breaking through the technical bottleneck of poor thermal conductivity of traditional foam materials, making full use of the excellent thermal conductivity of graphene, the thermal conductivity of the product exceeds 100W/m·K, which meets the needs of filling the gap and effectively improves the heat dissipation efficiency of the mobile phone, makes up for the gap of multi-dimensional requirements for thermal conductive materials at the 3C end, and brings a more comprehensive and efficient solution for technological development. In addition, because of its unique micro-nano cavity structure, the product can also provide necessary support and cushioning for the flexible screen, and can be widely used in energy storage batteries, new energy vehicles, mobile communication equipment, lightweight portable equipment and other fields in the future, and is an advanced thermal conductive multi-functional material.
