Adaptive thermochromic windows from active plasmonic elastomers

Thermochromic windows can smartly modulate the indoor solar irradiation, leading to energy saving for architectural heating and cooling systems. Herein, we integrate the active plasmonic VO 2 nanoparticles in kirigami-inspired reconfigurable elastomers to achieve adaptive, broadband, and highly efficient solar modulation. The smart window promises a UV-visible-NIR traverse state in cold days and a UV-visible-NIR blocked state in hot days to reduce the architectural heating and cooling energy consumption.Ministry of Education (MOE)National Research Foundation (NRF)This research was supported by the Singapore Ministry of Education (MOE) Aca-demic Research Fund Tier one, RG124/16 and RG200/17, and the National ResearchFoundation, Prime Minister’s Office, Singapore under its Campus for ResearchExcellence and Technological Enterprise (CREATE) programme
