Porous Janus-structured cellulosic materials for self-adaptive solar regulation

In the December 21, 2022 issue of Cell Reports Physical Science, Dastidar et al. report a Janus-structured cellulosic film that reflects most of the sunlight in a dry state and switches to absorbing sunlight for rapid water evaporation in a wet state. The property of self-adaptive solar-driven drying of this material is attractive and makes it applicable to thermal management and optical sensing.

Janus cellulose for self-adaptive solar heating and evaporative dryingDastidar et al.Cell Reports Physical ScienceDecember 15, 2022In BriefDastidar et al. report a cellulose-based sustainable and scalable Janus structure that demonstrates water-mediated dynamic control of optical absorption and solar-generated heat. Such tuning between low and high absorptive states offers new approaches for adaptive energy management. Full-Text PDF Open Access
