NOVELTY - Dipping solution comprises, 0.5-1.5 pts. wt. oxidized graphene and 100 pts. wt. water. USE - The dipping solution is useful for preparation of honeycomb material (claimed). ADVANTAGE - The dipping solution: does not use a high-density polymer resin material; has small density compared to density of the dipping liquid in the prior art, and thus it ensures the density of the honeycomb material after dipping is smaller and the weight of the honeycomb material is light under the same volume; and realizes the lightweight performance of the honeycomb material. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) preparation of dipping solution, comprising dissolving graphene oxide in water to obtain graphene oxide solution, and dissolving modified graphene and micro-nano iron powder in graphene oxide solution to obtain dipping solution; and (2) honeycomb material, comprises dipping solution, where the honeycomb material is obtained by dipping method.
