In addition, the conductive coating has good corrosion resistance and weather fastness, and base materials can be effectively protected for a long time.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an environment-friendly carbon fiber / polyacrylic acid conductive coating. Background technique [0002] With the rapid development of electronic technology, radio communication can be intensively configured and widely used, so that the space is filled with electromagnetic waves of different wavelengths and frequencies. These electromagnetic waves will interfere with the normal use of electronic products and become a new environmental pollution-electromagnetic wave interference. . Therefore, solving the interference caused by electromagnetic waves, preventing electromagnetic wave radiation pollution, protecting the environment, human health and ensuring information security have received extensive attention. There are many kinds of shielding materials, which can be divided into metal conductor materials, metal soft magnetic materials, ferrite soft magnetic materials, organic chemical mate...
