| Summary: | Polydimethylsiloxane (PDMS) is a material that has been extensively studied for its ability to facilitate passive cooling. Its high thermal stability, low thermal conductivity, and ability to conform to various surfaces make it an attractive material for use in radiative cooling applications.
Passive cooling properties of PDMS is achieved through introduction of porosities within the surface of the PDMS sponge. These voids facilitate the scattering and thermal emission from its surface. These voids are created using microsugar templates.
This project explores the use of hydrogel powder in place of sugar to recreate the porosities within the PDMS sponge and compare its radiative cooling properties with PDMS sponge fabricated with microsugar templates. |
