Abstract Rapid population growth in recent decades has intensified both the global energy crisis and challenges posed by climate change, including warming. Currently, increased frequency of extreme weather events large fluctuations ambient temperature disrupt thermal comfort negatively impact health, driving a growing dependence on cooling heating sources. Consequently, efficient management become central focus research. Traditional systems consume substantial energy, further contributing to greenhouse gas emissions. In contrast, emergent radiant technologies that rely renewable have been proposed as sustainable alternatives. However, achieving year-round without additional input remains formidable challenge. Recently, dynamic radiative emerged most promising solution, offering potential for energy-efficient adaptation across seasonal variations. This review systematically presents advancements management, covering fundamental principles, switching mechanisms, primary materials, application areas. Additionally, key hindering broader adoption are discussed. By highlighting their transformative potential, this provides insights into design industrial scalability these innovations, with ultimate aim promoting integration applications.

Abstract Flexible polyurethane foams are widely used in building and vehicle interiors due to their lightweight high resilience. However, most non‐biodegradable or fireproof, leading serious white foam pollution safety problems. Here, FPUF made of a porous MOF material loaded with flame retardant elements as coating is reported, which realizes fire protection, isolation heat noise, recovery foam. The results show that FPUF‐3 exhibited excellent smoke suppression effects, PHRR, CO production, 2 production reduced by 28.5%, 54.5%, 21.4%, respectively. shows longer preservation effect can reduce the common noise decibel >35%. In addition, exhibits stability under extreme acid–base conditions has durability effectiveness alkaline conditions. Furthermore, separation be realized ethanol solvent, rate reach >80%, still original elasticity characteristics. It provides sustainable practical solution for effectively improving reduction, prevention, insulation capabilities FPUF.

Radiative cooling technology has major benefits for energy-free thermoregulation since it can chill items without using any energy. However, the efficacy of radiative materials is hampered by outdoor pollution as well a number safety issues involved in practical applications, particular, fire hazard polymer-based materials. Here, porous composite film was created and manufactured that flame-retardant, cooling, superhydrophobic. The average infrared emissivity reached 97.2% with an solar reflectance up to 98.4%. It produced subambient environment, temperature decrease 11.5 °C. With sliding angle 3.6° water contact 158.7°, surface exhibits conventional self-cleaning properties Notably, flame-retardant limiting oxygen index 38.3%, which suitable requirements.

Radiative cooling (RC) technologies channel excess heat into outer space or cooler environments, potentially mitigating high temperatures in the built environment. However, despite progress research, transition from laboratory breakthroughs to widespread practical deployment remains challenging. In this Review, we aim bridge gap between theoretical studies and implementations of RC technology. Developments material science system architectures have begun facilitate transformation technology innovations towards real-world applications. We analyse three representative applications with different operation temperatures: thermal management buildings (sub-ambient temperature), personal comfort (near-ambient temperature) solar-cell (above-ambient temperature). also discuss current challenges opportunities encountered advancing for commercial use, such as ensuring that are economically viable, can be produced on large enough scales meet demands desired application perform effectively a range environments weather conditions. For uptake occur, collaboration among researchers, engineers industry stakeholders is needed design sustainable scalable manufacturing processes develop standardized protocols evaluating performance materials. passive approach could reduce reliance air conditioning. This Review outlines challenges, radiative control buildings, people solar cells.

Abstract Developing high-efficient flame-retardant coatings is crucial for fire safety polymer and battery fields. Traditional intumescent ceramifiable struggle to provide immediate prolonged protection simultaneously, which limits the applicability. To address this, an innovative bi-layered coating with organic/nano-inorganic additives inspired by differential response behaviors, enabling relay effect both fast-acting extended protection. Specifically, two layers function continuously in form of a relay. With mere 320 microns, withstands temperatures up 1400 °C at least 900 s. Consequently, effective prevented burn through aluminum plates glass fabric-reinforced epoxy resin, otherwise were burned 135 173 s, respectively. Meanwhile, suppressed formation decomposition solid interface layer lithium soft-package batteries, leading electrochemical stability safety. Additionally, fast endows polyurethane foam rapid self-extinguishing, preventing ignition even under exposure strong °C. Shortly, our work offers new insights into design development thin, high-performance, multi-application coatings.
