一种用于降低植物热应力的低成本、可大规模生产的聚合物多层辐射冷却膜
A Low-Cost and Large-Scale Producible Polymer Multilayer Radiative Cooling Film for Reducing Plant Heat Stress
中文简介
温室效应加剧了植物的热应激，对全球粮食生产和大气循环构成严重威胁。光谱选择性辐射冷却膜已被证明在缓解植物热应激方面具有巨大潜力。然而，由于基于真空的制造技术，它们的高成本和缓慢的生产速度阻碍了广泛应用。在这里，我们提出了一种通过使用聚合物多层辐射冷却膜来减少植物热应激的策略。该薄膜由两个光谱选择性聚合物多层薄膜堆栈和一个聚合物发射器组成。聚合物多层薄膜堆栈选择性地传输光合作用有效辐射（0.4-0.48 μm 波长为 52%，0.6-0.7 μm 波长为 85%）以促进光合作用，聚合物发射器具有高红外发射率，可实现出色的冷却性能。田间试验表明，该薄膜将空气温度降低 2.3-5.0 °C，将土壤表面以下 3 cm 处的温度降低 2.1-4.1 °C，使土壤水分蒸发减少 11.2-32.4%。因此，植物生物量产量提高了 21.1-195.9%。此外，多层共挤制备的高分子多层辐射冷却膜具有成本低、

cycling. Spectrally selective radiative cooling films have been proven to have great potential in alleviating plant heat stress. However, their high cost and slow production speeds due to vacuum-based fabrication techniques have hindered widespread application. Here, we propose a strategy to reduce plant heat stress by using a polymer multilayer radiative cooling film. This film consists of two spectrally
