▎ 摘　　要

NOVELTY - Preparing light nickel/nickel oxide assembled graphite alkenyl composite low-frequency wave-absorbing foam comprises (i) subjecting nickel complex solution to hydrothermal reaction to obtain nickel/nickel oxide composite; (ii) dispersing the nickel/nickel oxide composite and graphene in alcohol/aqueous mixed solution to obtain suspension; and (iii) subjecting suspension to freeze-solidification, freeze-drying and carrying out thermal reduction treatment in turn. USE - The method is useful for preparing light nickel/nickel oxide assembled graphite alkenyl composite low frequency wave-absorbing foam. ADVANTAGE - The foam has excellent wave absorbing performance in the low frequency S wave band, and has light weight and low density. The method is economical and has simple process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a light nickel/nickel oxide assembled graphite alkenyl composite low frequency wave-absorbing foam.
