“…[67] Zhang et el. [187] demonstrate impact-resistant windows with thermally tunable transmittance by reacting dodecanedioic acid (DDA) with glycerol to form an interconnected network of poly(glyceroldodecanoate) (PGD). The non-crosslinked DDA molecules form semicrystalline domains, which melt at 43.74 o C, also the phase transition temperature.…”

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.

“…[3,4] To decrease the impact of indoor heating and cooling on the environment, environmentally friendly and energy-saving alternatives are urgently needed. To date, several alternative technologies combining adaptive heating and cooling in one system have been developed, including smart windows, [5][6][7][8][9][10][11][12][13][14] Janus membranes, [15,16] and solar chimneys commercially available poly(dimethylsiloxane) (PDMS) precursor followed by curing in air ( Figure S1, Supporting Information). Similar to normal PDMS precursors, the emulsion needs about 6 days at room temperature to get fully cured, but could solidify within the first 20 min, accompanied by the fixation of the embedded water droplets.…”

Switchable Cavitation in Silicone Coatings for Energy‐Saving Cooling and Heating

et al. 2020

Space cooling and heating currently result in huge amounts of energy consumption and various environmental problems. Herein, a switching strategy is described for efficient energy‐saving cooling and heating based on the dynamic cavitation of silicone coatings that can be reversibly and continuously tuned from a highly porous state to a transparent solid. In the porous state, the coatings can achieve efficient solar reflection (93%) and long‐wave infrared emission (94%) to induce a subambient temperature drop of about 5 °C in hot weather (≈35 °C). In the transparent solid state, the coatings allow active sunlight permeation (95%) to induce solar heating to raise the ambient temperature from 10 to 28 °C in cold weather. The coatings are made from commercially available, cheap materials via a facile, environmentally friendly method, and are durable, reversible, and patternable. They can be applied immediately to various existed objects including rigid substrates.

“…For example, Lin and co‐workers mixed dodecanedioic acid (DDA) with glycerol to obtain a cross‐linked polyester network (PGD) as illustrated in Figure 5 A,B [64] . The material contains both amorphous domains (the cross‐linked PGD network) and semi‐crystalline domains (non‐cross‐linked DDA side chains, Figure 5 B).…”

A. R. Meier.After post-doctoral stays in the groups of J.-F. Lutz (ICS-CNRS, Strasbourg) and C. Barner-Kowollik (KIT), she currently works as asenior researcher at KIT.Her research interest spans from the synthesis of complex macromolecular architecturesand functional polymers to the development of new polymer-forming reactions and novel conjugation chemistries with aparticularfocus on the design of novel sulfur-based and self-reporting materials. Christopher Barner-Kowollik, Australian Research Council (ARC) Laureate Fellow, graduated in chemistry from Gçttingen University,G ermany,and joined the University of New South Wales in early 2000 rising to lead the Centre for Advanced Macromolecular Design in 2006 as one of its directors. He returned to Germany to the KIT in 2008, where he establishedand led aDFG-funded Centre of Excellence in soft matter synthesis. He moved to QUT in 2017 and established QUT'sSoft Matter Materials Laboratory. His research achievements have been recognized by an array of national and international awards.
