摘要
辐射冷却驱动的无源热电器件（rc - ted）提供了一种潜在的可持续能源解决方案。然而，大多数RC-TED策略使用不可持续的聚合物。本文开发了一种绿色可持续的二氧化碳交联纤维素（纸浆- co2），可同时用作被动辐射冷却膜和离子凝胶热电支架。与纯纸浆相比，二氧化碳以碳酸盐基团键的形式在纤维素主链中掺入，使膜具有优越的被动辐射冷却效果，并提高了离子凝胶的热电效率。在模拟太阳辐射（280 W m-2）下，由纸浆- co2膜和离子凝胶组成的集成RC-TED显示出令人印象深刻的1200 mV热电压输出，亚环境温度降低5.0°C，突出了其在低品位能量收集方面的潜力。因此，这种全纤维素启发的RC-TED设备展示了一种有前途的可持续战略，可以经济有效地将太阳能转化为电能。
CO2-crosslinked cellulose for radiative-cooling-driven passive thermoelectric devices: one stone, two birds.
Radiative-cooling-driven passive thermoelectric devices (RC-TEDs) offer a potentially sustainable energy solution. However, most RC-TED strategies utilize unsustainable polymers. Herein, a green and sustainable CO2-crosslinked cellulose (Pulp-CO2) was developed for simultaneous use as a passive radiative cooling membrane and an ionogel thermoelectric scaffold. The incorporation of CO2 in the form of carbonate group linkages in the cellulose backbone resulted in a superior passive radiative cooling effect of the membrane and improved the thermoelectric efficiency of the ionogel compared to the pure pulp. The integrated RC-TED, comprising the Pulp-CO2 membranes and ionogels, exhibited an impressive thermal voltage output of 1200 mV with a subambient temperature reduction of 5.0 °C under simulated solar radiation (280 W m-2), highlighting its potential in low-grade energy harvesting. Thus, this all-cellulose inspired RC-TED device showcases a promising and sustainable strategy for converting solar energy into electricity cost-effectively.
