Plastic pollution would be reduced by the use of sustainable, eco-friendly, and biodegradable devices. Starch is a readily available natural, edible, and biodegradable polymer. The strong hydrophilicity of starch hinders its use in the development of biodegradable triboelectric nanogenerators (TENGs), which must exhibit long-term stability. We enhanced the hydrophobicity of starch by introducing an edible Laver filler. A 1 wt % starch/Laver (SL) composite had a contact angle of 107°, which is far higher than that of pristine starch. We fabricated a fully packed SL-TENG using polycaprolactone (PCL) as the negative layer and edible gold leaf as the electrode. The PCL layer also served as the packaging layer, as it is stable in phosphate-buffered saline for 30 days. The 1 wt % SL-TENG exhibited 4- and 9-fold increased voltage and current outputs, respectively, compared to pristine starch. Finally, SL-TENG is utilized for biomechanical energy harvesting and for powering numerous electronics such as a calculator, stopwatch, wristwatch, and thermometer.

提高可生物降解材料摩擦纳米发电机中淀粉的疏水性
使用可持续、环保和可生物降解的设备可以减少塑料污染。淀粉是一种容易获得的天然、可食用和可生物降解的聚合物。淀粉的强亲水性阻碍了其在开发必须表现出长期稳定性的可生物降解摩擦纳米发电机 (TENG) 中的应用。我们通过引入一种可食用的紫菜填料来增强淀粉的疏水性。1 wt% 淀粉/紫菜 (SL) 复合材料的接触角为 107°，远高于原始淀粉的接触角。我们使用聚己内酯 (PCL) 作为负极层和可食用金箔作为电极制造了一个完全填充的 SL-TENG。PCL 层还用作包装层，因为它在磷酸盐缓冲盐水中可稳定 30 天。1 wt % SL-TENG 的电压和电流输出增加了 4 倍和 9 倍，分别与原始淀粉相比。最后，SL-TENG 用于生物力学能量收集以及为计算器、秒表、手表和温度计等众多电子设备供电。
