Exploiting biomass has raised great interest as an alternative to the fossil resources for environmental protection. In this respect, polyethylene furanoate (PEF), one of the bio‐based polyesters, thus reveals a great potential to replace the commonly used polyethylene terephthalate (PET) on account of its better mechanical, gas barrier, and thermal properties. Herein, a bio‐based, flexible, conductive film is successfully developed by coupling a PEF plastic substrate with silver nanowires (Ag NWs). Besides the appealing advantage of renewable biomass, PEF also exhibits a good transparency around 90% in the visible wavelength range, and its constituent polar furan moiety is revealed to enable an intense interaction with Ag NWs to largely enhance the adhesion of Ag NWs grown above, as exemplified by the superior bending and peeling durability than the currently prevailing PET substrate. Finally, the efficiency of conductive PEF/Ag NWs film in fabricating efficient flexible organic thin‐film transistor and organic photovoltaic (OPV) is demonstrated. The OPV device achieves a power conversion efficiency of 6.7%, which is superior to the device based on ITO/PEN device, manifesting the promising merit of the bio‐based PEF for flexible electronic applications.

生物基透明导电膜，由呋喃酸酯和银纳米线组成，用于柔性光电设备

生物质的开发引起人们极大的兴趣，希望将其作为化石资源的替代品来保护环境。在这方面，基于生物的聚酯之一的聚呋喃酸酯（PEF）因其更好的机械，阻气性和热性能而具有巨大的替代常规聚对苯二甲酸乙二醇酯（PET）的潜力。本文中，通过将PEF塑料基板与银纳米线（Ag NW）耦合，成功开发了基于生物的，柔性的导电膜。除了可再生生物质的吸引人的优势外，PEF在可见波长范围内还具有约90％的良好透明度，并且揭示了它的极性呋喃部分能够与Ag NW进行强烈的相互作用，从而大大增强了上面生长的Ag NW的附着力，如通过比目前流行的PET基材优异的弯曲和剥离耐久性所证明的。最后，证明了导电PEF / Ag NWs膜在制造高效柔性有机薄膜晶体管和有机光伏（OPV）中的效率。OPV设备实现了6.7％的功率转换效率，优于基于ITO / PEN设备的设备，体现了基于生物的PEF在柔性电子应用中的有前途的优点。
