Abstract

We introduce an innovative solution to reduce plastic dependence in flexible electronics: a biodegradable, water-resistant, and flexible cellulose-based substrate for crafting electrochemical printed platforms. This sustainable material based on ethyl cellulose (EC) serves as an eco-friendly alternative to PET in screen printing, boasting superior water resistance compared to other biodegradable options. Our study evaluates the performance of carbon-based screen-printed electrodes (SPEs) fabricated on conventional PET, recycled PET (r-PET), and (EC)-based materials. Electrochemical characterization reveals that EC-SPEs exhibit comparable analytical performance to both P-SPEs and rP-SPEs, as evidenced by similar limits of detection (LOD), limits of quantification (LOQ), and reproducibility values for all the analytes tested (ferro-ferricyanide, hexaammineruthenium chloride, uric acid, and hydroquinone). This finding underscores the potential of our cellulose-based substrate to match the performance of conventional PET-based electrodes. Moreover, the scalability and low-energy requirements of our fabrication process highlight the potential of this material to revolutionize eco-conscious manufacturing. By offering a sustainable alternative without compromising performance, our cellulose-based substrate paves the way for greener practices in flexible electronics production.

摘要

我们推出了一种创新解决方案，以减少柔性电子产品对塑料的依赖：一种用于制造电化学印刷平台的可生物降解、防水且柔性的纤维素基基材。这种基于乙基纤维素（EC）的可持续材料在丝网印刷中可作为PET的环保替代品，与其他可生物降解选项相比具有卓越的防水性。我们的研究评估了在传统PET、回收PET（r-PET）和基于（EC）的材料上制造的碳基丝网印刷电极（SPE）的性能。电化学表征表明，EC-SPE与P-SPE和rP-SPE均表现出相当的分析性能，这体现在所有测试分析物（铁氰化亚铁、六氨合钌（III）氯化物、尿酸和对苯二酚）的检测限（LOD）、定量限（LOQ）和重现性值相似。这一发现凸显了我们的纤维素基基材在性能上可与传统PET基电极相媲美的潜力。此外，我们制造工艺的可扩展性和低能量需求突出了这种材料在革新注重环保的制造方面的潜力。通过提供一种不影响性能的可持续替代品，我们的纤维素基基材为柔性电子产品生产中的更环保做法铺平了道路。
