Dual-mode temperature management technologies based on passive radiative cooling (PRC) and solar heating (SH) have garnered significant attention to adapt to seasonal temperature fluctuations. Yet, the development of switchable dual-mode temperature management materials featuring simple fabrication processes and superior thermal conductivity remains a challenge. Here, we demonstrate a dual-mode thermal regulator by assembling of Al₂O₃ and black Al nanoparticles directly on a high-thermal-conductivity Al sheet with laser surface direct writing (LSDW) and further spraying polytetrafluoroethylene (PTFE) as the self-cleaning layer. The thermal regulator has a high overall thermal conductivity of 32.1 W m⁻¹ K⁻¹. The black Al/PTFE side exhibits high solar absorptivity (~90%) and achieves an 11.3 °C temperature elevation in winter. The Al₂O₃/PTFE demonstrates excellent infrared emissivity (>96%) and high solar reflectivity (~90%), enabling 4.4 °C sub-ambient cooling in summer. PRC and SH can be switched by flipping to adapt to seasonal temperature variations. We envision this dual-mode thermal regulator has great potential for indoor energy-saving when integrated with buildings, offering a viable solution to address energy crises and reduce greenhouse gas emissions.
