▎ 摘  要

NOVELTY - Preparing nitrogen-doped graphene noble metal composite film, comprises: (i) uniformly mixing graphene oxide solution, water-soluble noble metal compound and water-soluble amine cross-linking agent to obtain a mixture, where the mass ratio of graphene oxide solution and water-soluble noble metal compound is (1:0.01)-(1:5), the water-soluble noble metal compound is water-soluble noble metal acid and/or water-soluble noble metal salt, the water-soluble amine cross-linking agent is ethylenediamine, propylene diamine, butanediamine, diethylenetriamine, triethylenetetramine, tetraethylenepentamine, ammonia, polyallylamine, hydroxylamine hydrochloride, hydrazine hydrate and/or p-phenylenediamine; (ii) coating the mixture to form a film, and drying at 20-95degrees Celsius to obtain amine crosslinked graphene oxide-noble metal composite film; and (iii) heating the composite film under the protection of inert gas to obtain the nitrogen-doped graphene-noble metal composite film. USE - The method is useful for preparing nitrogen-doped graphene noble metal composite film. ADVANTAGE - The method: achieves self-assembly of solidification into amine-based cross-linked graphene oxide noble metal composite film simultaneously in a single step; requires low reaction temperature; has simple and controllable operation; is environment-friendly and easy to operate; and suitable for large scale production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a nitrogen-doped graphene-noble metal composite film with high thermal conductivity of 800-1700 W/mK, preferably 900-1500 W/mK.
