Carbon materials have high specific surface area,high dielectric constant,and excellent thermal and electrical conductivity characteristics,and BaTiO3 has excellent dielectric properties. The combation of the two materials can effectively prevent and control electromagnetic pollution. In view of this,the BaTiO3/PAN nanofiber film was prepared by electrospinning method,and then the BaTiO3/carbon nanofiber mesh composite absorbing fabric was obtained by pre-oxidation and high temperature carbonization treatment. The nanofiber film prepared has the advantages of light,thin and wide bandwidth absorption. The results show that 2.0% BT/C has the best comprehensive performance,the carbon fiber arrangement is dense,the BaTiO3 crystal form is complete and well dispersed,and the reflection loss at 2.3 mm reaches −61.72 dB,and the maximum absorption bandwidth reaches 8.5 GHz,which has excellent wave absorption.
