Recently, WHHX Graphene Technology Co., Ltd. received an angel round investment of 200 million yuan. This round of funds will be mainly used for the construction of R&D centers and the expansion of large-scale production plants.
WHHX focuses on research and application development in the field of macrographene technology. The core technology of solid winding has formed a systematic patent group, covering core membrane materials, devices, processes and application systems.
The company closely relies on WH University of Science and Technology and HB Radio Frequency and Microwave Technology Research Center to develop a macro graphene film with high thermal conductivity and high electrical conductivity. The high thermal conductivity macro graphene film has obvious advantages compared with traditional metal thermal conductive materials. Among them, high electrical conductivity macro graphite The core conductivity of olefin film materials is the world's leading.
In the field of macrographene technology, WHHX has three advantages: large-scale engineering continuous production and manufacturing technology, the first graphene welding technology, and radio frequency technology advantages.
Relying on self-developed additives, WHHX solves the problem of integration of graphene films and metal equipment, and truly realizes the application of graphene materials in high-end fields such as chips and integrated circuits.
There are mainly two core technology products formed by WHHX. One is graphene heat dissipation film, which has better performance than artificial graphite film and is mainly used in the field of mobile phone heat dissipation. At present, high-end models of mobile phone manufacturers such as Huawei, Xiaomi, OPPO have been or planned this product. The second is the radio frequency antenna, which replaces the traditional aluminum etching antenna. Application areas include RFID antennas, mobile phone antennas, 5G base station antennas, router antennas, etc.
