The invention discloses a preparation method of a thin layer graphene polymer composite material. The method includes enabling a graphite intercalation compound and/ or thin layer graphene with a catalyst adsorbed on the surface and at least one polymer monomer to form a mixed reaction system and conducting catalytic polymerization reaction under the set condition to obtain the thin layer graphene polymer composite material. An intercalation agent in the graphite intercalation compound and the catalyst are at least selected from any one of inorganic acid, organic acid, halogen, metal salt and metal oxide. The preparation method is simple in process, easy to implement, safe, environment-friendly, low in cost and suitable for industrial batch production. Further, the obtained composite material can be applied to lithium ion battery electrode materials or super capacitor electrode materials.
