再生纤维素薄膜（RCF）由于其可降解性、透明性和柔韧性等特点，具有作为导电基材的潜力。铟掺杂氧化锡（ITO）是一种传统的导电材料，但其刚性限制了柔性导电膜的形成。在本研究中，银纳米线（AgNWs）被引入到RCF和ITO导电框架之间。此外，还进行了柔性、导电、透明RCF的制备。通过添加50 μL AgNWs- ito，该RCF具有较高的电导率（170 Ω / sq）和透明度（78%）。在以5mm曲线半径弯曲样品50次后，制备的导电RCF的电阻提高了19%，而对照ito基RCF的电阻提高了485%。这是AgNWs框架的结果，它可以减少导电层上弯曲处理的破坏，也可以理想地连接ITO导电部分。这种新方法可以加快柔性导电RCF在可打印、便携式和可穿戴电子设备上的广泛应用。
Regenerated cellulose film (RCF) has potential as a conductive substrate due to features such as its degradability, transparency, and flexibility. Indium doped tin oxide (ITO) is a conventional conductive material, but its rigidity restricts the formation of flexible conductive film. In this study, silver nanowires (AgNWs) were introduced between the RCF and the ITO conductive framework. Additionally, the fabrication of flexible, conductive, and transparent RCF was conducted. The AgNWs-ITO based RCF demonstrated high conductivity (170 Ω per sq) and transparency (78%) by the addition of 50 μL of AgNWs. After bending the sample 50 times with a 5 mm curve radius, the as-prepared conductive RCF presented an electric resistance improvement of 19%, with a 485% increase for the control ITO-based RCF. This is a result of the AgNWs framework, which can lessen the destruction of the bending treatment on the conductive layer and can also desirably connect the ITO conductive sections. The novel approach can expedite the versatile applications of flexibly conductive RCF on printable, portable, and wearable electronic devices.
