【摘要】 纳米材料具有优异的性能和广阔的应用前景，被誉为跨世纪的新材料，引起了科学界和企业界的极大关注。随着纳米材料的出现，薄膜技术也得到相应的发展，纳米薄膜的研究随之成为薄膜研究的新热点。时至今日，已从单一材料的纳米薄膜转向纳米复合薄膜的研究，出现了多样化的制备工艺，且朝着多种技术的复合、化学组分的多组元化等方向发展。本文首先采用浸渍—提拉法在玻璃基底上制备不同材料的纳米涂层。研究基底厚度、聚乙烯醇缩丁醛（PVB）对纳米涂层热辐射性能的影响；研究不同纳米涂层的热辐射性能。结果表明厚度为1.2mm的玻璃基底热辐射性能优于其它两种基底；使用聚乙烯醇缩丁醛对纳米涂层的热辐射性能的影响很小；TiO₂纳米涂层的热辐射性能优于其它纳米材料涂层。其次采用黑体实验设备、红外光谱仪分析基底、TiO₂纳米涂层在红外波段的吸收性能。结果表明玻璃在2000cm^-1—800cm^-1区域内对红外光强烈吸收；TiO₂纳米涂层在3800cm^-1—2400cm^-1区域内对红外光的吸收较好。采用磁控溅射仪在玻璃基底上制备TiO₂／SiO₂纳米多层复合膜；用椭圆偏振测厚仪测试薄膜的厚度和折射率；用黑体实验设备测试复合膜的热辐射特性，用红外光谱仪分析复合膜在红外波段的吸收特性。结果表明复合膜的总厚度为2μ，折射率为1.20。黑体实验表明TiO₂／SiO₂多层膜在波长800nm—1600nm范围内有较强的吸收，且随着温度的升高吸收率变大。红外光谱表明TiO₂／SiO₂多层膜在波数2300cm^-1—2900cm^-1范围内的吸收较明显。实验的结果对TiO₂／SiO₂多层膜将来在红外波段的应用具有一定的参考价值。更多还原

【Abstract】 Nanometer materials have excellent properties and amplitude applied foreground, which are called new material of the new century and have attracted attention in science field and enterprise field. With the appearance of nanometer material, thin film technology have developed quickly, then the study of nanometer thin film have became new focus in the thin film field. Up to now, the study of film have turned from single nanometer thin film into nanometer multiple thin film, bring various prepared technics, and develop towards composite of multi-technology and multiplex of chemic element and so on.Nanometer coating of the different materials is prepared on substrates by dip-coating.The effect of thermal radiation properties of nanometer coating is studied though the thickness of substrates and pvb, as well as thermal radiation properties of different nanometer coating. The result shows that thermal radiation properties of 1.2mm prefer to other two substrates; The effect of pvb is very little on thermal radiation properties of nanometer coating, the thermal radiation properties of TiO₂ nanometer coating is prefer to the others. The absorption of substrates and TiO₂ nanometer coating were analyzed by Blackbody Equipment and Infrared Spectroscopy in the infrared wave band. The result shows that glass has a well infrared absorption within the wavenumber range of 2000cm^-1—800cm^-1; TiO₂ nanometer coating has a well infrared absorption within the wavenumber range of 3800cm^-1—2400cm^-1.TiO₂/SiO₂ nanomultilayers were prepared on glass substrates with magnetron sputtering. The thickness and refractive index of the thin films were measured by the ellipsometer; the thermal radiation properties of multilayers were tested by blackbody equipment, the absorption of multilayers at infrared wave band were analyzed by Infrared Spectroscopy. The result shows thickness of multilayers is 2μ, refractive index is 1.20. Blackbody Radiation Experiment shows that TiO2/SiO2 nanomultilayers have a well infrared absorption within the wavelength range of 800nm to 1600nm, and the absorption coefficient increases as the temperature rises. Infrared Spectroscopy shows that TiO₂/SiO₂ nanomultilayers have a well infrared absorption within the wavenumber range of 2300cm^-1—2900cm^-1, which will have some help for apply of the TiO₂/SiO₂ nanomultilayer.更多还原
