Abstract
High-transparent and flexible Au nanofiber films were successfully fabricated by a combination of electrospinning technique and ion sputtering technology, in the presence of polyvinylpyrrolidone(PVP) nanofiber films as template. The as-prepared Au nanofiber films show typical interconnected nonwoven nanofiber networks, and the average diameters of Au nanofibers range from 291 nm to 322 nm. When sputtering time is 75 s, the average transmittance of the as-prepared Au nanofiber film in visible region is 92%, the reflectance in near infrared region is about 7%, and the resistivity is 2. 9x10(-3) Omega . cm. Importantly, after 500 cycles of bending, the as-prepared Au nanofiber films show no obvious electrical degradation. The Au nanofiber films with transparent and near-IR reflective properties may provide promising applications for flexible liquid crystal displays, solar cells and flexible and transparent functional electronics.
