▎ 摘 要
NOVELTY - The method involves pre-processing a supporter. A tubular ceramic membrane is chosen as a supporting body. The supporting body is flushed and dried. An end of the supporting body is connected with a glue seal. Another end of the supporting body is connected with a vacuum pump through a pipeline. Film liquid of graphene material is dissolved in solvent. A uniform dispersion liquid film is processed. The film is immersed in the liquid. The film is set in a vacuum drying box at 25 degrees centigrade to 50 degrees centigrade. USE - Stone type black graphene composite film material preparing method. ADVANTAGE - The method enables ensuring simple film formation process. DESCRIPTION OF DRAWING(S) - The drawing shows a graph representing a stone type black graphene composite film material preparing method. '(Drawing includes non-English language text)'
