▎ 摘　　要

NOVELTY - Wave-absorbable lead-ion graphene comprises lead ions and graphene molecules, where the lead ions are arranged in a molecular lattice of graphene and the lead ions absorbs nuclear radiation and cosmic rays. A wave-absorbable tin-ion graphene comprises tin ions and graphene molecules, where the tin ions are arranged in a molecular lattice of graphene and the tin ion graphene absorbs infrared rays and ultraviolet rays. USE - Used as wave-absorbable lead-ion graphene. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the wave-absorbable lead-ion graphene, comprising (i) adding 1 mol lead ion liquid solution with 3 mol graphite material and adding non-ionic chelates as osmotic agent and accessing the graphene lattice lead ion; (ii) adding the accessed lead ion graphene mixed material into the reaction vessel for ion insertion reaction, controlling pH to 6.8-8.4 and reacting at 350-500 degrees C for 8 hours; and (iii) drying the reaction product and measuring the factory parameters in accordance with standards of the product of factor.
