Today's consumer electronics, such as cell phones, tablets and other portable electronic devices, are typically made of non-renewable, non-biodegradable, and sometimes potentially toxic (for example, gallium arsenide) materials. These consumer electronics are frequently upgraded or discarded, leading to serious environmental contamination. Thus, electronic systems consisting of renewable and biodegradable materials and minimal amount of potentially toxic materials are desirable. Here we report high-performance flexible microwave and digital electronics that consume the smallest amount of potentially toxic materials on biobased, biodegradable and flexible cellulose nanofibril papers. Furthermore, we demonstrate gallium arsenide microwave devices, the consumer wireless workhorse, in a transferrable thin-film form. Successful fabrication of key electrical components on the flexible cellulose nanofibril paper with comparable performance to their rigid counterparts and clear demonstration of fungal biodegradation of the cellulose-nanofibril-based electronics suggest that it is feasible to fabricate high-performance flexible electronics using ecofriendly materials.

基于可生物降解的纤维素纳米原纤维纸的高性能绿色柔性电子产品。

当今的消费电子产品，例如手机，平板电脑和其他便携式电子设备，通常由不可再生，不可生物降解的材料制成，有时还具有潜在的毒性（例如砷化镓）。这些消费类电子产品经常被升级或丢弃，从而导致严重的环境污染。因此，期望由可再生和可生物降解的材料以及最小量的潜在有毒材料组成的电子系统。在这里，我们报告了高性能柔性微波和数字电子产品，它们在基于生物的，可生物降解的和柔性纤维素纳米原纤维纸上消耗了最少量的潜在有毒物质。此外，我们以可转移的薄膜形式展示了砷化镓微波设备，这是一种消费无线产品。
