Preparation and transparent heat insulating properties of aqueous acrylic–amino–alkyd coatings with CuS nanoplates

Preparation and characterization of PVC/CsxWO3 composite film with excellent near‐infrared light shielding and high visible light transmission

“…Optical properties of the polyvinyl chloride/hexagonal cesium tungsten bronze (PVC/Cs x WO 3 ) composite films: (A) the digital photos of the PVC/Cs x WO 3 composite films, (B) the transmittance curves of the PVC/Cs x WO 3 composite films, (C) the near‐infrared (NIR) shielding rate and visible light transmittance of the different polymer/inorganic nanoparticles composite materials reported in the literature, including indium tin oxide (ITO), [ 28 ] antimony tin oxide (ATO), [ 29 ] aluminum zinc oxide (AZO), [ 16 ] lanthanum hexaboride (LaB 6 ), [ 17 ] copper sulfide (CuS), [ 19 ] potassium tungsten bronze (K x WO 3 ), [ ] sodium tungsten bronze (Na x WO 3 ), [ 39 ] this work [Color figure can be viewed at wileyonlinelibrary.com]…”

“…After 60 min of sunlight simulation radiation, it is expected that the bare glass reached the highest temperature (63 C), and the plasticized PVC film without adding Cs x WO 3 slurry also reached 62 C, indicating pure plasticized PVC film does not have the performance of cooling and heat insulation. When 0.3 phr of Cs x WO 3 slurry is indium tin oxide (ITO), [28] antimony tin oxide (ATO), [29] aluminum zinc oxide (AZO), [16] lanthanum hexaboride (LaB 6 ), [17] copper sulfide (CuS), [19] potassium tungsten bronze (K x WO 3 ), [] sodium tungsten bronze (Na x WO 3 ), [39]…”

“…CuS nanoparticles are the newly developed and have the characteristics of low cost, easy modification, excellent photostability, and intrinsic NIR region absorption, which can be used as ideal NIR shielding materials. [ 18 ] Han et al [ 19 ] used CuS as the thermal insulation nanomaterial and acrylic‐amino‐alkyd baking varnish as coating‐forming material to prepare a novel aqueous transparent heat insulation coating, which has excellent transparency in the visible light region and strong absorption in the NIR region when applied to the glass surface. However, one of the limitations of CuS nanoparticles as a NIR shielding agent is their low absorption ability in the region of 1300–2500 nm.…”

Dark, Infrared Reflective, and Superhydrophobic Coatings by Waterborne Resins

“…Recently, deeply colored infrared reflective pigments, e.g., black, blue, and red pigments, have been developed. , However, coatings containing such dark pigments are also easily contaminated. The pollutants in the air are readily adsorbed and adhered to the surface of the coating, negatively affecting its NIR-reflectivity . A lot of manpower and energy are required to clean the contaminated surface. − Therefore, NIR-reflective coatings need to be further functionalized with self-cleaning properties.…”
