In this study, a silver nanowires (AgNWs)/nano-zinc oxide (ZnO)/polyvinylpyrrolidone (PVP) film is fabricated as an alternative to indium tin oxide transparent conductive films (TCFs). AgNWs are prepared by the polyol method with PVP as a dispersant to prevent Ag nanoparticles agglomeration during AgNWs formation. Nano-ZnO is synthesized using sol–gel method. AgNWs/ZnO/PVP TCFs are prepared using the electrostatic spinning and spin coating methods for comparison. It is found that the best PVP/AgNO3 molar ratio is 3.5:1. FTIR and XRD analyses show that 500°C calcination leads to better crystallinity and purity of nano-ZnO. Four-point prober analysis indicates that the higher the AgNWs content, the lower the TCF sheet resistance. The best sheet resistance of AgNWs/ZnO/PVP TCF by the electrostatic spinning method is obtained as 81 Ω/sq, and the light transmittance is 85.3%. Moreover, in the 5-week stability test, the sheet resistance of the electrospun TCF increases by 6.17%, much lower than 24.9% of the spin coated TCF. It is verified that the elecrospun AgNWs/ZnO/PVP composite TCF is a promising alternative to the traditional ITO TCFs.

静电纺银纳米线/ZnO/PVP复合透明导电薄膜的制备及表征

在这项研究中,制造了银纳米线(AgNW)/纳米氧化锌(ZnO)/聚乙烯吡咯烷酮(PVP)薄膜作为氧化铟锡透明导电薄膜(TCF)的替代品。采用多元醇法以 PVP 作为分散剂制备 AgNWs,以防止 Ag 纳米粒子在 AgNWs 形成过程中团聚。纳米ZnO采用溶胶-凝胶法合成。使用静电纺丝和旋涂方法制备AgNWs/ZnO/PVP TCFs以进行比较。结果发现最佳的PVP/AgNO 3摩尔比为3.5:1。 FTIR 和 XRD 分析表明,500°C 的煅烧导致纳米 ZnO 具有更好的结晶度和纯度。四点探针分析表明AgNWs含量越高,TCF方块电阻越低。采用静电纺丝法得到AgNWs/ZnO/PVP TCF的最佳方块电阻为81 Ω/sq,透光率为85.3%。此外,在5周稳定性测试中,静电纺TCF的方块电阻增加了6.17%,远低于旋涂TCF的24.9%。事实证明,电纺AgNWs/ZnO/PVP复合TCF是传统ITO TCF的有前景的替代品。
