Innovative Electrochromic Films Offer Smart Solutions for Indoor Climate Control

New MOF-based coatings can quickly switch colors to manage light and heat, enhancing energy efficiency in buildings.

Researchers developed electrochromic films using metal-organic frameworks (MOFs) for dynamic light and heat regulation.
The films transition between transparent, green, and red states with voltage changes, aiding in glare reduction and thermal insulation.
The MOF-based films can switch colors in just 2 seconds and maintain their state for 40 hours without additional voltage.
These films performed reliably through 4,500 cycles of color switching, indicating strong durability.
Potential applications include smart windows and intelligent optical devices for better indoor temperature management.
