Abstract:

A 3D hierarchically porous poly (vinyl alcohol)-co-poly (ethylene) nanofibrous membrane is compounded with an epoxy matrix and ultraviolet light absorbers (2,4-dihydroxybenzophenone). Owing to the strong interfacial interactions between the nanofibers and the epoxy, the obtained composite transparent substrate shows excellent flexibility, high transparency and high ultraviolet light-filtering effect. The AgNWs film and the reduced graphene oxide film are successively coated on the flexible substrate by a facile pressure transfer method to form the inter-penetrating conductive networks. The resulting composite transparent conductive film possesses a sheet resistance of 147 Ω/Sq, a visible light transmittance of 80%, and an ultraviolet light absorption over 90%. The film also exhibits excellent tensile and bending properties and maintains high electrical stability during cyclic bending tests.
