Porous polymer coatings dynamically control light and heat

The porous polymer coatings, which switch from white to transparent when wetted, can be put into plastic enclosures to make panels that control light and temperatures of buildings. Image: Jyotirmoy Mandal/Columbia Engineering

The researchers demonstrated that PPC-based roofs, which can switch between reflective and transmissive states, can be used to control the indoor temperatures of buildings. Image: Jyotirmoy Mandal/Mingxin Jia/Columbia Engineering
