Abstract

The invention relates to a 1,1-diacetylferrocene chiral poly-schiff base salt / graphene composite wave absorbing material. The 1,1-diacetylferrocene chiral poly-schiff base salt / graphene composite waveabsorbing material is a chiral conductive polymer composite material. The material is prepared by compounding the chiral 1,1-diacetylferrocene chiral poly-schiff base salt with the graphene and thenadding a paraffin matrix. The composite material has the advantages of simple and convenient preparation process and low density; in addition, by combining the preparation process with chiral characteristic of the composite material, the composite material has strong practical value in electromagnetic wave absorbing materials, electromagnetic shielding, electromagnetic radiation protection and thelike.

Description

technical field [0001] The invention relates to a 1,1-diacetylferrocene chiral poly-Schiff base salt / graphene composite wave-absorbing material. The composite wave-absorbing material belongs to electromagnetic wave absorbing materials and belongs to the technical field of wave-absorbing materials. Background technique [0002] The absorbing material is generally composed of a matrix material and an absorbing medium, which can absorb the electromagnetic wave energy projected on its surface, and convert the electromagnetic wave energy into heat energy or other forms of energy through the dielectric loss of the material. In addition to having a high absorption rate for electromagnetic waves in a wide frequency band, excellent wave-absorbing materials also need to have properties such as light weight, temperature resistance, moisture resistance, and corrosion resistance. Traditional absorbing materials such as ferrite, metal powder, barium titanate, silicon carbide, graphite, co...
