Reversible thermochromic cellulose-based agricultural film with radiation cooling for agricultural cultivation.

The increase in extreme weather events results in more temperature fluctuations, which have a profound impact on crop growth, development, and yields. In this work, cellulose-based agriculture films with dual thermoregulation functions of radiative cooling and thermochromism were prepared by doping thermochromic microcapsules with rice straw cellulose as raw materials. Wherein the fibrous rice straw cellulose dissolved in the ionic liquid is converted to a lamellar structure, and the thermophilic thermochromic microcapsule is wrapped in it.
