| titleOfInvention | Integrated impedance gradient flexible wave-absorbing material and preparation method thereof |
| abstract | The invention discloses an integrated impedance gradient flexible wave-absorbing material and a preparation method thereof. The integrated impedance gradient flexible wave-absorbing material comprises a base material and an MXene/PPy complex which is combined on the surface of the base material and in the pores of the base material; the MXene/PPy composite refers to a composite formed by MXene and PPy particles attached to the pores or edges of the MXene sheets; the concentration of PPy particles in the MXene/PPy composite body is gradually changed along the thickness direction of the base material; the base material is open-pore sponge, non-woven fabric or three-dimensional space fabric with pore structure and thickness. According to the invention, the polymerization rate and diffusion distribution of the PPy are regulated and controlled by a freezing interface polymerization or gas phase polymerization method, so that the concentration of the PPy can be distributed in a gradient manner from top to bottom in the thickness direction of the polymer substrate loaded with MXene in the polymerization process, and further the impedance gradient is realized. The addition of PPy will increase the dipole polarization and increase the heterointerface, and adjust the impedance mismatch caused by too high conductivity of MXene. The wave-absorbing material has good impact resistance, air permeability and environmental stability. |
