摘要

废物管理,特别是电子废物,提出了重大的环境挑战。同样,大量产生的农业和粮食废物也造成相当大的处置和处理费用。为了解决这两个问题,本研究探索了从农业副产品中提取的可再生资源创造环境友好型电子材料的潜力。具体来说,可持续的电子导体是通过将番茄植物废料转化为导电的、可生物降解的材料而开发的。这是通过使用水基方法将石墨烯纳米片(GnPs)与水解番茄废料整合在生物基乳胶基质中实现的。重要的是,在不需要分离特定成分的情况下使用水解番茄废物代表了一种全生物质利用策略。这种方法简化了处理过程,同时最大限度地提高了农业废物的价值。结果表明,含有20 wt.% GnPs的乳胶-番茄废弃物复合材料具有良好的机械性能和耐湿性,电阻率为0.46 Ω·m。值得注意的是,它可以有效地作为记录水果生物阻抗的电极。这些发现证明了这种材料作为绿色电子产品的可持续替代品的潜力,同时有助于在循环经济框架内减少电子和农业废物。

Plant-Based Electrodes for Bioimpedance Readings of Fruit

Waste management, particularly electronic waste, presents significant environmental challenges. Similarly, agricultural and food waste, produced in large quantities, also imposes considerable disposal and processing costs. Addressing both of these issues, this study explores the potential of creating environmentally friendly electronic materials from renewable resources derived from agricultural byproducts. Specifically, sustainable electronic conductors are developed by converting tomato plant waste into conductive, biodegradable materials. This is achieved by integrating graphene nanoplatelets (GnPs) with hydrolyzed tomato waste in bio-based latex matrices using water-based methods. Importantly, the use of hydrolyzed tomato waste without the need for isolating specific components represents a whole-biomass utilization strategy. This approach simplifies processing while maximizing the valorization of agricultural waste. The resulting latex–tomato waste composite containing 20 wt.% GnPs exhibits satisfying mechanical properties and moisture resistance, along with a resistivity of 0.46 Ω · m. Notably, it serves effectively as an electrode for recording the bioimpedance of fruits. These findings demonstrate the potential of this material as a sustainable alternative for green electronics, while simultaneously contributing to the reduction of both electronic and agricultural waste within a circular economy framework.
