Abstract

Invited for this month's cover is a combined work of the Korea Research Institute of Chemical Technology together with the Chungnam National University, the University of California, Irvine, and Chung-Ang University. The cover shows the effective thermal management of a vehicle interior through the wrapping of stretchable passive radiative cooling film. Thermoplastic polyurethane (TPU) cooler film with a hierarchical porous structure shows a dramatic cooling effect compared to commercial paint in sunny, hot weather. The Research Article itself is available at 10.1002/cssc.202201842.
