摘要

短期使用电子产品的生产和处置由于资源的密集使用、危险的加工和日益增长的电子废物而对环境造成重大影响。我们提出了一种生物基碳墨水的合成，作为一种可持续的印刷电子功能材料，展示了它在非涂布纸基板上作为温度传感器和加热器的应用潜力，以实现完全生物基和潜在的可生物降解器件。对于温度传感，获得了-2.3 * 10-3 K−1的电阻热系数，而加热元件在0.5 W时的温度高达160°C。

Bio-based carbon as functional material in sustainable printed electronics

The production and disposal of short-term-use electronics pose significant environmental implications due to intensive resource use, hazardous processing, and growing electronic waste. We present the synthesis of a bio-based carbon ink as a sustainable functional material for printed electronics, demonstrating its application potential as temperature sensor and heater on uncoated paper substrate for the realization of fully bio-based and potentially biodegradable devices. For temperature sensing, a thermal coefficient of resistance of –2.3 * 10^–3 K⁻¹ was obtained, while the heating element exhibited temperatures of up to 160 °C at 0.5 W.
