Next-generation printed electronics is required to be of high performance, cost-effective, multifunctional, sustainable, and environmentally benign. Herein, we report the manufacturing of a flexible carbon-coated paper for printed electronics ensuring the abovementioned requirements. The multifunctional carbon-coated substrate is achieved by employing copy paper, cellulose nanofibers (CNFs), and lignin-derived graphitic carbon as a base substrate, binder, and conductive pigment, respectively, using the scalable and simple Mayer rod coating and calendering methods. The pressure applied by the calendering led to a 96% decrease in electrical resistance for the carbon-coated paper. Wettability analysis revealed that the carbon layer is hydrophilic and capable of hydrogen bonding. The dielectric constant is obtained to be an order of magnitude less than that of the copy paper, indicating that the CNF binder between the carbon particles impedes the polarization mechanism. The impedance is measured as frequency-dependent and capacitive. The resistance, impedance, and dielectric values suggest that the carbon-coated paper is favorable for capacitive applications. Fabricating the flexible substrate with the biobased binder and conductive pigment introduces a significant step in sustainable and environmentally friendly printed electronics for future flexible capacitors, sensors, and wearable devices, especially for the applications where end-of-life disposal needs to be sustainable.

用于印刷电子产品的木质素衍生碳涂层功能纸

下一代印刷电子产品需要高性能、低成本、多功能、可持续和环境友好。在此,我们报告了用于印刷电子产品的柔性碳涂层纸的制造,以确保上述要求。多功能碳涂层基材是通过使用复印纸、纤维素纳米纤维 (CNF) 和木质素衍生的石墨碳分别作为基础基材、粘合剂和导电颜料,使用可扩展且简单的 Mayer 棒涂布和压延方法实现的。压光施加的压力导致碳涂层纸的电阻降低了 96%。润湿性分析表明,碳层是亲水的并且能够形成氢键。获得的介电常数比复印纸的介电常数小一个数量级,表明碳颗粒之间的 CNF 粘合剂阻碍了极化机制。阻抗被测量为频率相关的和电容性的。电阻、阻抗和介电值表明碳涂层纸有利于电容应用。使用生物基粘合剂和导电颜料制造柔性基板为未来柔性电容器、传感器和可穿戴设备的可持续和环保印刷电子产品迈出了重要一步,特别是对于需要可持续报废处理的应用。阻抗被测量为频率相关的和电容性的。电阻、阻抗和介电值表明碳涂层纸有利于电容应用。使用生物基粘合剂和导电颜料制造柔性基板为未来柔性电容器、传感器和可穿戴设备的可持续和环保印刷电子产品迈出了重要一步,特别是对于需要可持续报废处理的应用。阻抗被测量为频率相关的和电容性的。电阻、阻抗和介电值表明碳涂层纸有利于电容应用。使用生物基粘合剂和导电颜料制造柔性基板为未来柔性电容器、传感器和可穿戴设备的可持续和环保印刷电子产品迈出了重要的一步,特别是对于需要可持续报废处置的应用。
