Graphene thermal insulation
WebThe IR laser irradiation of graphene oxide in vacuum reduces the oxygen content at low and high fluences. The IR laser irradiation of GO in air enhances the oxygen content at fluences lower than 400 mJ/cm(2): at these fluences thermal oxidation processes are present. WebMar 18, 2024 · The thermal conductivity of the coated cotton increased in the order of graphene > BN > MWCNT at the same coating content, reaching to a maximum of 0.29 ± 0.015 W m−1 K −1 with 50 wt % graphene coating. Graphene also provided a better heat dissipation than BN and MWCNT but lower air permeability.
