One-Step Process for High-Performance, Adhesive, Flexible Transparent Conductive Films Based on p‑Type Reduced Graphene Oxides and Silver Nanowires
This
work demonstrates a one-step process to synthesize uniformly dispersed
hybrid nanomaterial containing silver nanowires (AgNWs) and p-type
reduced graphene (p-rGO). The hybrid nanomaterial was coated onto
a polyethylene terephthalate (PET) substrate for preparing high-performance
flexible transparent conductive films (TCFs). The p-rGO plays the
role of bridging discrete AgNWs, providing more electron holes and
lowering the resistance of the contacted AgNWs; therefore, enhancing
the electrical conductivity without sacrificing too much transparence
of the TCFs. Additionally, the p-rGO also improves the adhesion between
AgNWs and substrate by covering the AgNWs on the substrate tightly.
The study shows that coating of the hybrid nanomaterials on the PET
substrate demonstrates exceptional optoelectronic properties with
a transmittance of 94.68% (at a wavelength of 550 nm) and a sheet
resistance of 25.0 ± 0.8 Ω/sq. No significant variation
in electric resistance can be detected even when the film was subjected
to a bend loading with a radius of curvature of 5.0 mm or the film
was loaded with a reciprocal tension or compression for 1000 cycles.
Furthermore, both chemical corrosion resistance and haze effect were
improved when p-rGO was introduced. The study shows that the fabricated
flexible TCFs have the potential to replace indium tin oxide film
in the optoelectronic industry
