▎ 摘　　要

NOVELTY - An absorbing honeycomb material preparing method involves preparing a graphene oxide dispersion having a stable concentration, performing a solvothermal reaction on the graphene oxide dispersion to obtain a graphene hydrogel having a three-dimensional network skeleton structure, coating the graphene hydrogel onto a honeycomb core material, and drying and curing the coated honeycomb core material to obtain the finished product. USE - Method for preparing absorbing honeycomb material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a absorbing honeycomb material prepared by the method.
