▎ 摘  要

NOVELTY - Three-dimensional self-assembled structure absorbing material comprises graphene and polythiophene, where the graphene is spongy material and polythiophene is grown within the graphene pores. USE - Used as three-dimensional self-assembled structure absorbing material. ADVANTAGE - The absorbing material has hydrophobic angle of 123 degrees , good waterproof performance, thickness of 3 mm, reflection loses of less than -10 dB and absorption frequency band width of 5.5 GHz, and can be mixed with paraffin according to mass ratio of 1:9. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the three-dimensional self-assembled structure absorbing material, comprising (i) preparing graphite oxide or graphene oxide dispersion, adding into a reaction kettle, adding concentrated aqueous ammonia, heating and reacting, (ii) freeze drying to obtain three-dimensional structure graphene, (iii) dissolving 2,5-dibromo-3,4-ethylenedioxythiophene in chloroform to form 0.05-0.3 g/ml concentration solution, adding three-dimensional structure graphene and adsorbing for 30-60 minutes, and (iv) desorbing and removing three-dimensional structure graphene and completely evaporating chloroform at not greater than 70 degrees C.
