▎ 摘　　要

NOVELTY - A through hole graphene foam is prepared by depositing graphene saturated solution on metal foam framework sintered with copper base plate by boiling deposition, removing metal foam framework to obtain hollow diameter of graphite foam as template, depositing graphene saturated solution on template by boiling deposition, removing template, and drying. USE - Preparation of through hole graphene foam (claimed). ADVANTAGE - The preparation is simple, has high heat flow density and reduced pollution and toxicity, maintains saturation on boiling deposition of graphene, and reduces damage for human body and production cost. DESCRIPTION OF DRAWING(S) - The drawing shows an electron microscope image of prepared through hole graphene foam.
