The present invention further provides a method of producing a composite heat dispatching plate coated with nitrogen-doped graphene film, comprising: mixing a nitrogen-doped graphene obtained aforementioned with a polymer bonding agent to form a mixture slurry, coating the mixture slurry onto at least one surface of a metal substrate to form a composite material, drying the composite material, and obtaining the composite heat dispatching plate with a film of nitrogen-doped graphene. Structural defects of graphene lattices are reduced during doping process so that crystallinity and thermal conductivity are improved. Methods of the present invention may be conducted under normal pressure using commercially available solid-state nitrogen sources without adding polluting solvents to provide a safe, stable and cost effective preparation of composite heat dispatching material."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of preparing nitrogen-doped graphene and method of producing composite heat dispatching plate thereof","description":"The present invention relates to a method of preparing nitrogen-doped graphene, comprising: mixing at least one solid-state nitrogen containing precursor with a graphene to form a mixture, and sinteri","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10494557","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
