▎ 摘　　要

NOVELTY - Preparing low frequency P-wave absorbing material comprises (i) using first surfactant to modify the graphene powder to obtain a functionalized graphene dispersion; (ii) mixing functionalized graphene dispersion with spherical magnetic alloy particles by a high-energy ball milling method to obtain a functionalized graphene/flaky magnetic alloy particle composite absorbent; (iii) coating the functionalized graphene/flaky magnetic alloy particle composite absorbent with a second surfactant to obtain a low-frequency P-band absorbent; and (iv) rubber mixing and calendering after the low-frequency P-band absorber is mixed with ethylene-propylene-diene rubber. USE - The method is useful for preparing low frequency P-wave absorbing material. ADVANTAGE - The method adjusts absorption bandwidth of the wave absorbing material in the range of 0.3-1 GHz. The material has good mechanical and construction properties after molding; and is easy to adhere to the surface of various structural parts. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for low frequency P-wave absorbing material prepared as mentioned above.
