The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase II project will reduce energy consumption in buildings and automobiles via 'smart' solar control window films. The effects of solar heating are frequently experienced on sunny warm days when the inside temperature of a car can exceed 130°F in minutes. The same solar heating that is such a nuisance in summer is very much desired in winter. The national problem is that buildings consume more than 41% of all energy produced (more than 50% directly for heating, cooling, and lighting) which leads to an estimated 2,236M metric tons of greenhouse gases. Additionally, 80% of buildings that exist today will exist in 20 years, many of which are inefficient and outdated. This necessitates a retrofittable smart solar control film. The consequence of installing smart solar control film is that the sun's warmth can be harnessed when it is needed and reflected away when it is unneeded. Installing these highly transparent films will have significant energy savings in space heating, cooling, and lighting. If smart solar control films are implemented, the Department of Energy estimates as much as 1.0 quadrillion BTUs ($10B in cost savings) can be saved annually.This Small Business Innovation Research (SBIR) Phase II project focuses on commercializing a family of doped nanoceramic materials that exhibit near-room temperature metal-to-insulator phase transitions. Slight changes to the composition of matter produce remarkably tunable thermochromic transitions over a broad range of temperatures, filling a key technological gap for their deployment as a smart solar control window film. No visible change occurs during the transition from the low-temperature/infrared transparent (insulating-like phase) to the high-temperature/infrared reflective (metal-like phase), and vice versa. The nanomaterials are also of sufficient stability, optical clarity, and compatible with commonly used polymers found in film. Phase II efforts address optimizing the composition of matter for peak performance and developing a unique in-line nanomanufacturing process compatible with scalable production and achieving more precise control. In order for these materials to perform correctly they need to be of the correct elemental composition and be in the form of nanoparticles of the correct size. The films will be optimized and then thoroughly tested in the laboratory and in the field for their performance, stability, optical clarity, and a wide variety of application-specific performance requirements.

这一小型企业创新研究(SBIR)二期项目的更广泛影响/商业潜力将通过“智能”太阳能控制窗膜减少建筑物和汽车的能源消耗。在阳光明媚、温暖的日子里，车内温度在几分钟内就能超过130华氏度时，经常会遇到太阳能供暖的影响。同样的太阳能供暖在夏天是如此令人讨厌，但在冬天却是非常令人向往的。全国性的问题是，建筑物消耗了超过41%的能源(超过50%直接用于供暖、制冷和照明)，这导致了大约22.36亿吨的温室气体。此外，今天存在的80%的建筑将在20年后存在，其中许多建筑效率低下且过时。这就需要一种可改装的智能太阳能控制薄膜。安装智能太阳能控制薄膜的结果是，太阳的温暖可以在需要时被利用，在不需要时被反射走。安装这些高度透明的薄膜将在空间加热、制冷和照明方面节省大量能源。如果智能太阳能控制薄膜被实施，能源部估计每年可以节省多达1.0万亿BTU(节省100亿美元的成本)。这个小型企业创新研究(SBIR)第二阶段项目专注于将一系列掺杂纳米陶瓷材料商业化，这些材料表现出近室温的金属到绝缘体的相变。对物质组成的微小改变可以在广泛的温度范围内产生显著可调的热致变色转变，填补了将其部署为智能太阳能控制窗薄膜的关键技术空白。在从低温/红外透明(类绝缘相)到高温/红外反射(类金属相)的转变过程中没有发生明显的变化，反之亦然。纳米材料还具有足够的稳定性、光学清晰度，并与薄膜中常见的聚合物兼容。第二阶段的工作旨在优化物质的组成，以实现最佳性能，并开发一种独特的在线纳米制造工艺，与可扩展生产兼容，并实现更精确的控制。为了使这些材料正确运行，它们需要具有正确的元素组成，并且具有正确大小的纳米颗粒的形式。薄膜将经过优化，然后在实验室和现场对其性能、稳定性、光学清晰度和各种特定应用的性能要求进行彻底测试。
