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.

We aim to explore bionanocellulose/alginate/polyethylene glycol/thermochromic dye (BNC/ALG/PEG/TD) as a thermo-responsive hydrogel film. In this study, BNC was produced using Pichia kudriavzevii USM-YBP2. Then, the morphology of observed transmission electron microscope (TEM). The formation film utilized ionic crosslinking technique by mixing BNC, ALG, PEG, and thermochromic (TD) with Ca2+ ions. evaluated for its swelling property, behavior, biodegradability. exhibits aggregated fiber clusters spherical shape. BNC/ALG/PEG/TD formed gray film, which indicates successful integration TD. Interestingly, it shows acceptable stability in wet dry conditions, suggesting robustness stability. However, demonstrated low water content (16.6%) compared control probably because increment crosslink density or improvement polymer-polymer interaction. changes drastically colorless at temperatures >30°C proving behavior. also presented reversible thermochromism property that enables reverse back original color morphology. slow degradation needs more than 2 weeks fully degrade. conclusion, can be potentially explored smart wide area applications.

Experimental Study on the Photothermal Properties of Thermochromic Glass

Buildings, Journal Year: 2025, Volume and Issue: 15(2), P. 233 - 233

Published: Jan. 15, 2025

Reducing energy consumption in buildings is critical to reducing CO2 emissions and mitigating global warming. Studies have shown that heating cooling loads account for more than 40% of building consumption, thermochromic glass (TCG) with dynamically adjustable solar transmittance an excellent way reduce this load. Although a large number studies tested the spectral parameters TCG totally transparent turbid states, impact dynamic changes optical properties on simulation accuracy has been neglected. In study, method proposed hydrogel-type test its based spectrophotometry. The uses spectrophotometer PID heater achieve parameter testing TCGs at different temperatures. paper, transmission reflection spectra two 20~25 °C, 30~35 40 45 50 55 °C were obtained, regression segmentation functions visible established. R2 function model 0.99. addition, results show selected paper can selectively transmit wavelengths light, mainly occurs near-infrared from 320 1420 nm, while rate other very low. As temperature increases, visible, solar, ultraviolet transmittances decrease similar rate. higher acting (TC) layer, greater haze.
