| 摘要: 以五水合四氯化锡、三氯化锑为原料，乙醇为溶剂，氨水为沉淀剂，乙酸异戊酯为共沸溶剂，共沸蒸馏干燥前驱体溶胶，650℃煅烧后制备了单分散不同锑掺杂量的掺锑二氧化锡（ATO）纳米颗粒。结果表明，锑含量对颗粒粒径、光电性质具有重要影响，10mol%锑掺杂量时，样品具有最低的电阻率以及最优良的光学性质（最高的可见光透过率与近红外屏蔽效果），电学性质。ATO与聚氨酯复合涂膜玻璃隔热测试表明，涂层薄膜具有优良的隔热效果，能够有效地减小热量的传递与扩散。 |

| Abstract: Sb-Doped SnO2 (ATO) nanoparticles with different antimony doping levels were synthesized by azeotropic drying of the precursor using isoamyl acetate as the azeotropic solvent and then calcined at 650℃ for 1 h. The obtained ATO nanoparticles possess tetragonal structure with uniform particle size. Antimony doping content has great effect on the optical and electrical properties of the ATO nanoparticles, as well as the particle size. With antimony doping content of 10mol%, the ATO nanoparticles have the lowest resistivity and the best optical properties which have good transmittance in visable and big reflection in NIR region. The films of waterborne polyurethane, which are complexed with ATO nanoparticles, as the thermal insulating test on the glass substrates showed excellent heat insulating effect, and can block the heat transfer and diffusion effectively. |
