|Researchers at Purdue University have developed an improved formulation of sub-ambient radiative cooling paint with improved durability and mechanical properties for large-scale production. This approach incorporates a binder developed by the industry that is known to weather well. By offering enhanced hydrophobic and mechanical properties than previous solutions, the self-cleaning paint has greater readiness for adoption. Applications of this technology lie in passive radiative cooling for residential and commercial spaces, electronics, and more in order to improve cost and energy efficiency.
- Hydrophobic properties allow for self-cleaning paint
- Ability to have a higher pigment loading due to strength of binder
- Designed to fit within existing industry manufacturing platforms
- Rooftop of commercial and residential buildings
- Equipment or toolboxes exposed outdoors for communication network
- Electronics cooling
Technology Validation: This technology has been validated through testing of the paint and comparison against prior solutions. The solar reflectance of the paint was demonstrated to be 96.7-97.5% depending on the pigment loading of the mixture.
