Benefits of technology

The present invention is a new type of graphene sheet that combines a flexible graphite flake structure with high heat and electric conductivities. This graphene sheet has excellent flexibility and can be easily attached to heat sources with different shapes. It also has good heat conductivity and can serve as an electromagnetic shielding material. The graphene sheet is made by mixing graphite nanoplatelets and graphene materials in a slurry. Overall, this invention provides a flexible and efficient solution for heat dissipation and electromagnetic shielding in electronic devices.

Problems solved by technology

However, the higher temperature may affect the properties of the electronic components.
Moreover, it the operation temperature is too high, the electronic components may have permanent damages.
If the heat-dissipating device is not flexible, it cannot fit the irregular shape of the heat source.
That is, the heat-dissipating device may not attach to the surface of the heat source as large as possible, thereby reducing the heat dissipating performance.
