以CuS纳米片为太阳能隔热功能纳米材料，丙烯酸氨基醇酸烘漆（AAA）为成膜物质，制备了一种新型水性透明隔热涂料（C-X-Y）。C-X-Y涂层应用于普通玻璃基板的表面。这些C-X-Y涂覆的玻璃基板在可见光区域（390-780 nm）具有良好的透明度，并且在近红外区域（780-1750 nm）具有强吸收。例如，具有1.0重量% CuS纳米片（C-1.0-150）的150 μ m厚的C-X-Y涂层可以透射60%的可见光并屏蔽80%的近红外光。在250 W红外灯照射下，C-X-Y涂层C-1.0- 150的箱内稳定温度比参比涂层（不含纳米CuS）低12.0 °C。基于CuS纳米片在可见光区的选择性透明和在近红外区的选择性屏蔽等特性，CuS纳米片独特的光电性能使其在建筑和交通工具等节能环保领域具有潜在的应用前景。
A novel aqueous transparent heat insulation coating (C–X–Y) with CuS nanoplates as solar heat insulating functional nanomaterial and acrylic-amino-alkyd baking varnish (AAA) as coating-forming material was prepared. TheC–X–Ycoating was applied to the surface of ordinary glass substrates. ThoseC–X–Ycoated glass substrates have good transparency in the visible region (390–780 nm) and strong absorption in the near-infrared region (780–1750 nm). For instance, a 150 μm-thickC–X–Ycoating with 1.0 wt% CuS nanoplates (C–1.0–150) can transmit 60% visible light and shield 80% near-infrared light. The stable temperature inside the box covered with theC–X–YcoatingC–1.0–150was 12.0 °C lower than that with the reference coating (without nano-CuS) under the irradiation of a 250 W infrared lamp. Based on their special characteristics, such as selective transparency in the visible region and selective shielding in the near-infrared region of solar light, the CuS nanoplates based transparent heat insulation coatings might have a potential application in architectures and vehicles for energy saving and environmental protection due to the unique optoelectronic properties of the CuS nanoplates.
