摘要:

通过静电纺丝技术与离子溅射镀膜法, 以电纺聚乙烯吡咯烷酮(PVP)为模板, 制备了高透明的柔性金(Au)纳米纤维膜. 研究表明, 该柔性Au纳米纤维膜呈现无规网状分布, 纤维的平均直径为291~322 nm. 当Au的溅射时间为75 s时, 所得薄膜的可见光透过率为92%, 近红外反射率为7%, 电阻率为2.9×10-3Ω·cm. 该Au纳米纤维膜可转移到任何柔性基底上, 且显示出优异的柔韧性, 在弯曲500 次后其电阻率基本不变.

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 2.9×10-3 Ω·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.

Key words: Electrospinning, Au nanofiber, Ion sputtering, High-transparent flexible conducting film
