This Small Business Innovation Research (SBIR) Phase I research project will develop a low-cost nano-composite self-assembled thermoelectric system via a commercially viable manufacturing process. Control of homogeneity at the molecular level dictates the ultimate performance of the thermoelectric material, which is quantified by the Figure of Merit, ZT. High values of the Figure of Merit (preferably 2 or greater) are only achievable by strict control of molecular deposition, which is attainable via self-assembly processing. Self-assembly represents a method for rapid, aqueous based, room temperature deposition of molecularly uniform material layers. This synergistic manufacturing approach combines properties obtained only via nano-structured materials for macro scale structural components. Potential applications of nano-structured, low-cost, self-assembled thermo-electrics include remote power generation, commercial refrigeration and air conditioning, and cooling for electronics and optics. Consumer and corporate products would benefit via replacement of chlorofluorocarbon (CFC) based cooling units. Replacement with thermoelectric modules facilitates an environmentally friendly, precisely controlled thermal management solution for nearly any refrigeration or air conditioning application. Thermoelectric modules can also take advantage of waste heat generation from industrial and private operations to generate auxiliary power for such systems.

这个小企业创新研究（SBIR）第一阶段研究项目将通过商业上可行的制造工艺开发一种低成本的纳米复合材料自组装热电系统。在分子水平上对均匀性的控制决定了热电材料的最终性能，其通过品质因数ZT来量化。高品质因数值（优选2或更大）仅可通过严格控制分子沉积来实现，这可通过自组装加工来实现。自组装代表了一种用于快速、水基、室温沉积分子均匀材料层的方法。这种协同制造方法结合了仅通过纳米结构材料获得的宏观尺度结构部件的特性。纳米结构、低成本、自组装热电的潜在应用包括远程发电、商业制冷和空调以及电子和光学冷却。消费者和企业产品将受益于氟氯化碳（CFC）的冷却装置的替代。更换为热电模块有助于为几乎任何制冷或空调应用提供环境友好、精确控制的热管理解决方案。热电模块还可以利用工业和私人运营产生的废热为此类系统产生辅助电力。
