Flexible transparent conductive films (TCFs) have attracted tremendous interest thanks to the rapid development of portable/flexible/wearable electronics. TCFs on basis silver nanowires (AgNWs) with excellent performance are becoming an efficient alternative replace brittle metal oxide. In this study, a promising method was developed by introducing SiO2 hollow nanospheres (SiO2–HNSs) into film significantly improve AgNW-based TCFs. Since SiO2–HNSs opposite charges AgNWs, strong attraction had promoted uniform distribution AgNWs and made distance between closer, which could decrease contact resistance greatly. The introduction layer remarkably enhanced transmission visible light conductivity. addition, constructed showed much higher thermal stability adhesive force than those only AgNWs. As example, AgNW/SiO2–HNS-coated poly(ethylene terephthalate) (PET) increase about 14.3% in comparison AgNW-coated PET. Typically, AgNW/SiO2–HNS-based TCF sheet 33 Ω/sq transmittance 98.0% (excluding substrate) be obtained flexibility, adhesion, stability. At last some devices were fabricated.
