Facile synthesis of flexible graphene-silver composite papers with promising electrical and thermal conductivity performances

Free-standing and flexible graphene-silver (GE-Ag) composite paper has been successfully fabricated through an evaporation of graphene oxide-AgNO ₃ aqueous aerosol followed by a chemical reduction. The size, thickness and shape of the GE-Ag paper can be tuned according to the Teflon substrate used. The GE-Ag paper presents the advantages of good flexibility, high electrical conductivity (159 Ω per sq) and good thermal conductivity in the vertical direction (3.3 W mK^-1), which are more optimal than the pure GE paper.
