▎ 摘　　要

NOVELTY - A substrate comprises a flexible substrate and an electroconductive layer. The flexible substrate is a transparent dielectric polymer material optionally doped with graphene. The electroconductive layer is a silver nano wire film having gap filled with graphene, or transparent dielectric polymer material doped with graphene. USE - Substrate for flexible photoelectronic appliances. ADVANTAGE - The substrate is manufactured with improved bonding strength between silver nano wire film and flexible substrate. The silver nano wire film is formed with favorable roughness. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of substrate, which involves washing rigid substrate whose surface roughness is less than 1 nm, blowing dry nitrogen, preparing silver nano wire film on clean substrate by spinning or spraying or automatically assembling or spray ink printing or silk-screen printing, spinning or spraying transparent dielectric polymer material layer doped with graphene on silver nano wire film, or spinning or dropping or spraying solution containing graphene, then spinning or spraying transparent dielectric polymer material layer, thermally curing surface of rigid substrate, peeling silver nano wire film and cured transparent dielectric polymer material or transparent dielectric polymer material doped with graphene from rigid substrate to form flexible electroconductive substrate, and testing transmissivity, conductivity and surface topography of flexible electroconductive substrate.
