Unraveling the Radiative Cooling Properties of Inexpensive, Ubiquitous and Biodegradable Cellulose Materials.

Radiative cooling is a passive cooling mechanism that enables objects to dissipate heat by emitting infrared radiation to the cold expanse of outer space. In this presentation, we will unveil the latest findings from our research into the radiative cooling capabilities of cellulose materials. Our investigations have revealed the remarkable potential of specific cellulose composites to achieve substantial radiative cooling effects, with temperature differentials as impressive as 15 degrees Celsius below ambient conditions without using any external energy. Moreover, we have conducted comprehensive measurements to quantify the radiative cooling power exhibited by these cellulose composites and naturally occurring biodegradable cellulose.

The applications of this research extend beyond theoretical understanding. These cellulose-based radiative cooling materials hold promise for a wide range of practical applications. From enhancing the thermal comfort of clothing in hot and humid climates to contributing to energy-efficient building materials and cooling technologies, the possibilities are vast. We would explore cellulose-based radiative cooling its potential to revolutionize sustainable cooling technologies without contributing to global warming and improve the quality of life in various environmental conditions.
