    摘要:

    研究不同形貌的銣、銫鎢青銅粉末及其薄膜的性能。通過水熱反應(yīng)制備棒狀和片狀的銣、銫鎢青銅納米粉末,并對粉末進(jìn)行熱處理,之后使用旋涂法在玻璃上制備鎢青銅透明隔熱薄膜。通過X射線衍射、掃描電鏡、透射電鏡等對粉末進(jìn)行表征,并研究其光熱性能。使用紫外可見近紅外光譜分析鎢青銅薄膜近紅外屏蔽性能,并測試其隔熱性能。結(jié)果表明,熱處理后的鎢青銅粉末具有優(yōu)異的光熱性能,具有光熱治療癌癥的應(yīng)用前景。相比于棒狀,片狀的銣、銫鎢青銅薄膜具有更高的近紅外屏蔽率,分別為95%和98.8%。使用片狀銣、銫鎢青銅薄膜的玻璃室內(nèi)溫度相比使用空白玻璃分別下降了9.4℃和8.5℃。綜上,片狀銣、銫鎢青銅具有優(yōu)異的近紅外屏蔽性能,在節(jié)能和光熱治療領(lǐng)域具有巨大的應(yīng)用前景。

    Abstract:

    In order to investigate the properties of rubidium tungsten bronze and cesium tungsten bronze nanopowders with different shapes and their film, rubidium and cesium tungsten bronze nanopowders were prepared by hydrothermal reaction and a subsequent heat-treatment. Tungsten bronze transparent insulation film was prepared by spin coating method on a piece of glass. The synthesized powders were characterized by X-ray diffraction, scanning electron microscopy and transmission electron microscopy, and the photothermal properties of the powders were studied. The near infrared shielding performance and heat insulation performance of tungsten bronze films were analyzed by UV-Vis NIR spectroscopy. The results show that the tungsten bronze nanopowders after heat treatment have excellent photothermal properties and have a promising application prospect in cancer photothermal therapy. Compared with the film made by rod-shaped powers, the film made by laminar rubidium and cesium-tungsten bronze powders have higher near-infrared shielding performance of 95% and 98.8%, respectively. Compared with blank glass, the indoor temperature using glass with laminar rubidium and cesium tungsten bronze films decreased by 9.4℃ and 8.5℃ respectively. In summary, sheet rubidium and cesium tungsten bronze have excellent near-infrared shielding performance, and have great application prospects in the fields of energy saving and photothermal therapy.
