In this study, an innovative strategy is introduced to transform transparent polydimethylsiloxane into a versatile material via laser-induced pyrolysis. By precisely controlling laser intensity, the material is engineered for multi-thermal management, exhibiting high reflectivity and thermal emission for effective cooling under high-energy processing and strong solar absorption for notable heating under low-energy conditions. Simulation results indicate that applying this material to building roofs could reduce annual energy consumption by up to 26.5%. Moreover, its capability to form Janus structures and all-laser-patterned solar thermoelectric devices highlights its potential for sustainable technologies. This work represents a pioneering strategy in sustainable thermal management for cooling and heating, demonstrating a novel use of a monolith material and a facile fabrication technique and offering a promising solution to global environmental challenges.
