With the rapid development of 5G technology, the number of 5G base station constructions is rapidly increasing. It is expected that by 2025, the number of 5G base stations worldwide will reach 65 million. 5G base stations not only require more antennas and larger bandwidth, but also higher base station density to ensure effective transmission and communication of information. However, this also brings about the problem of electromagnetic pollution, which urgently needs effective measuresElectromagnetic wave protection materialGraphene absorbing materials, as a new type of material, have shown great potential in electromagnetic wave protection.

Characteristics of Graphene Absorbing Materials

Graphene is a two-dimensional nanomaterial with excellent conductivity and unique physicochemical properties. Its electronic motion speed can reach 1/300 of the speed of light, making it one of the best conductive materials currently known. The valence and conduction bands of graphene intersect at the Fermi level, endowing it with unique zero bandgap semiconductor properties. In addition, graphene also has a super high specific surface area (theoretical specific surface area can reach 2630m ²/g), which can be used for adsorption and desorption of various large molecules and small particles.

However, the main electromagnetic wave attenuation mechanism of pure graphene is electrical loss, and its absorption performance is relatively limited. In order to improve its absorption performance, graphene is usually composite with other materials such as ferrite or electrically lossy metal compound nanoparticles. This composite method can not only effectively solve the problems of poor dispersion and easy aggregation of nanoparticles, but also dissipate electromagnetic waves through interface polarization, electronic relaxation polarization, and dipole polarization effects.
