Abstract
Passive thermal management of an object can be achieved by manipulating its optical spectrum. Here, we present a protocol to create a dual-mode Janus fabric (DMJF) with unique switchable thermal management properties. We describe steps for fabricating radiative cooling (RC), ultraviolet (UV) reflective, and long-wave infrared (LWIR) shielding layers. We then detail steps for optical characterization and permeability and thermal measurements for the fabricated samples. This protocol could be applicable to various dynamic passive thermal management scenarios under diverse climatic conditions. For complete details on the use and execution of this protocol, please refer to Pian et al.(1).
