“…6). Some transition metal complexes (TMCs) that exhibit thermochromism with little T lum loss at high temperature are chosen to be hybridized with VO 2 nanoparticles [45,68,84]. The used TMCs can partly absorb visible light and change color as a response to temperature change upon interaction with an appropriate donor solvent and effectively avoid severe damage to T lum at high temperature because the absorption peaks are staggered with the extremum of the light-adapted eye sensitivity function.…”

“…The used TMCs can partly absorb visible light and change color as a response to temperature change upon interaction with an appropriate donor solvent and effectively avoid severe damage to T lum at high temperature because the absorption peaks are staggered with the extremum of the light-adapted eye sensitivity function. The thermochromic ionic liquid (IL) has been used by Zhu et al [68]. Briefly, when heating from room temperature, the ionic liquid-nickel-chlorine (IL-Ni-Cl) complexes absorb increasing visible light around 656 nm and 705 nm, and gradually change color from colorless to blue.…”

“…That means that the transmittance in the visible light region for VO 2 smart coating of metallic state should be maintained at least 50%, while the coating shows higher luminous transmittance of semiconducting state. Some works have been reported to increase DT sol of VO 2 by mixing with specific materials shows a robust contrast in the visible light region in different temperatures [45,68]. However, more investigations are required for a facile and cheap method to achieve the balance between luminous transmittances and solar modulation ability of VO 2 based smart coatings.…”

With an urgent demand of energy efficient coatings for building fenestrations, vanadium dioxide (VO 2 )-based thermochromic smart coatings have been widely investigated due to the reversible phase transition of VO 2 at a critical transition temperature of 68°C, which is accompanied by the modulation of solar irradiation, especially in the near-infrared region. As for commercial applications in our daily life, there are still some obstacles for VO 2 -based smart coatings, such as the high phase transition temperature, optical properties (luminous transmittance and solar modulation ability), environmental stability in a long-time period, as well as mass production. In this review, recent progress of thermochromic smart coatings to solve above obstacles has been surveyed. Meanwhile, future development trends have also been given to promote the goal of commercial production of VO 2 smart coatings.

Architectural windows that smartly regulate indoor solar radiation by changing their optical transmittance in response to thermo-stimuli have been developed as a promising solution toward reducing the energy consumption of buildings. Recently, energy-efficient smart window technology has attracted increasing scientific interest, with the exploration of energyefficient novel materials as well as integration with practical techniques to generate various desired multi-functionalities. This review systematically summarizes emerging thermoresponsive materials for smart window applications, including hydrogels, ionic liquids, perovskites, metamaterials, and liquid crystals. These are compared with vanadium dioxide (VO2), a conventional and extensively studied material for thermochromic smart window applications. In addition, recent progress on cutting-edge integrated techniques for smart windows is covered, including electro-thermal techniques, self-cleaning, wettability and also 2 integration with solar cells for bifunctional energy conservation and generation. Finally, opportunities and challenges relating to thermochromic smart windows and prospects for future development are discussed. features (Figure 1b); (2) passivity, with their automatic response to temperature cutting down the need for switch systems, for example electrical control requiring external energy and human manipulation; (3) rational stimulus-response, with regulation by indoor temperature rather than UV-triggered optical modulation in photochromic materials. The table of contents entry:Smart windows are promised significant contribution to the economization of building energy consumption. The rapid development of thermoresonsive materials and integrated techniques provide novel directions beyond conventional pure VO2-based thermochromic smart windows. The review summarizes emerging materials, including hydrogels, ionic liquids, perovskites, and metamaterials and integrated techniques, covering electro-thermal devices, self-cleaning, wettability, and integration with solar cells.

Windows play significant roles in commercial and residential buildings and automobiles, which direct and control light illumination, thermal insulation, natural ventilation, and aesthetics. Various approaches are attempted to make windows “smart” by tailoring their transparency and thermal insulation in response to environmental changes. Hence, there has been much effort to develop smart windows that can dynamically modulate the transmission and reflectance of the visible light and solar radiance into buildings according to weather conditions or personal preferences. Development of smart window materials is also beneficial to applications including wearable sensors, energy harvesting and storage, and medical devices. By carefully matching the refractive indices of nanoparticle (NPs) and polymer matrix, surface chemistry, and their mechanical properties, particle‐embedded polymer composites can exhibit synergistic effects with improved chemical and mechanical stability, enhanced dispersion of NPs, and optimized and stimuli‐responsive optical properties. Here, an overview of recent progresses in the development of smart windows based on electro‐, thermo‐, and mechanoactuations is provided. Additional functionalities, e.g., flexibility, stretchability, and mechanical/chemical stability, can also be achieved by careful choices of NPs and polymers.
