The authors explore the development of paper-based electronics using carbon-based composites with a biodegradable matrix based on ethyl cellulose and dibasic ester solvent. The main focus is on screen-printing techniques for creating flexible, eco-friendly electronic devices. This research evaluates the printability with the rheological measurements, electrical properties, flexibility, and adhesion of these composites, considering various compositions, including graphene, graphite, and carbon black. The study finds that certain compositions offer sheet resistance below 1 kΩ/sq and good adhesion to paper substrates with just one layer of screen printing, demonstrating the potential for commercial applications, such as single-use electronics, flexible heaters, etc. The study also shows the impact of cyclic bending on the electrical parameters of the prepared layers. This research emphasizes the importance of the biodegradability of the matrix, contributing to the field of sustainable electronics. Overall, this study provides insights into developing environmentally friendly, flexible electronic components, highlighting the role of biodegradable materials in this evolving industry.
作者们探索了使用基于乙基纤维素和二元酯溶剂的具有可生物降解基质的碳基复合材料来开发纸质电子产品。主要重点是用于制造柔性、环保电子设备的丝网印刷技术。本研究通过流变学测量、这些复合材料的电学性能、柔韧性和附着力来评估其可印刷性，考虑了包括石墨烯、石墨和炭黑在内的各种成分。研究发现，某些成分只需一层丝网印刷就能提供低于1 kΩ/sq的表面电阻以及与纸质基材的良好附着力，证明了其在一次性电子产品、柔性加热器等商业应用中的潜力。该研究还展示了循环弯曲对所制备层的电学参数的影响。本研究强调了基质生物降解性的重要性，为可持续电子领域做出了贡献。总体而言，这项研究为开发环境友好型、柔性电子元件提供了见解，突出了可生物降解材料在这个不断发展的行业中的作用。
