NOVELTY - Density gradient type high hydrogen storage composite film resistant to irradiation of charged particles is claimed. The composite protective film layer is a zinc oxide film deposited on the surface of the cobalt sulfide (Co9S8) metal compound, then adding it to the graphene, high-energy ball milling under protection of protective gas, adding acetone after taking it out, and ultrasonically dispersing to uniformity, adding 70-80 degrees C epoxy resin, stirring quickly at constant temperature of 70-80 degrees C until the acetone solvent evaporates completely, then adding the curing agent, magnetically stirring until the mixture is uniform, coating on the surface of the substrate with same surface density to form film, drying and then hydrogenating. USE - Used as density gradient type high hydrogen storage composite film resistant to irradiation of charged particles. ADVANTAGE - The composite film: adopts atomic layer deposition technology to deposit zinc oxide film on the surface of cobalt-sulfur metal compound, and then prepares high-hydrogen storage cobalt-sulfur metal compound through high-energy ball milling technology; improves bonding ability of hydrogen storage material and matrix. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing density gradient type high hydrogen storage composite film resistant to irradiation of charged particles. The method utilizes zinc source, substrate, oxygen source, curing agent, epoxy resin and acetone.
