▎ 摘 要
NOVELTY - A nano-scaled graphene article comprises a non-woven aggregate of nano-scaled graphene platelets to form an electrical network of platelets in contact with other platelets to form several conductive pathways along the article. Each of the platelet comprises a graphene sheet or multiple graphene sheets and the platelets have a thickness not greater than 100 nm. The article has an electrical conductivity of not less than 200 S/cm or a thermal conductivity not less than 400 Wm-1K-1. USE - For thermal management in micro-electronic devices and for current-dissipating on an aircraft skin against lightning strikes. ADVANTAGE - The article has a thermal conductivity greater than 300 (preferably greater than 500, especially greater than 1000, particularly greater than 1500) Wm-1K-1; and an electrical conductivity greater than 200 (preferably greater than 300, especially greater than 1000, particularly greater than 3000) S/cm. The article is highly conductive thin-film article.
