This Small Business Technology Transfer Phase I project will develop a new system for fabrication and manipulation of carbon nanotube (CNT) composites. The system will use holographic optical trapping (HOT) with a spatial light modulator (SLM) and a new form of nano-controlled photo-polymerization. This tool will allow the creation of a new class of carbon-nanotube polymer composite materials with unprecedented control over the material structure, including orientation, distribution, tangling and shape, in a variety of different polymer hosts. Realization of these new material systems will facilitate systematic exploration of the mechanical, thermal, and electrical properties and structure-property relationships in organized carbon-nanotube composites.The broader impact/commercial potential of this project relates not only the development of a new class of engineered materials but also to improvement of available nanofabrication methods and technology for multi-trap holographic optical trapping (HOT) systems. The new nanofabrication system to be developed will open new avenues for fabricating nanomaterial systems which were previously unsuitable for industrial fabrication. The development of a system capable of producing moderate volumes of material creates a means for systematic study of the macroscopic properties of carbon-nanotube/polymer composite structures. One potential market for carbon-nanotube composites is as an alternative to Indium Tin Oxide (ITO). ITO is widely used in the rapidly growing display market and in the infrared optical device market. However, due to the high cost and limited supply of Indium, alternative transparent conductors are highly desirable. Additionally, there are well over a hundred published research groups pursuing optical trapping, primarily for biological research, who would represent a sizable market for advances in the HOT method. This market demands continued improvement of technology, and the incorporation of these systems into complex microscope tools has piqued the interest of microscope manufacturers in active wave-front modulation devices as optional product accessories.

这个小企业技术转让第一阶段项目将开发一个新的系统，用于制造和操纵碳纳米管（CNT）复合材料。 该系统将使用具有空间光调制器（SLM）的全息光学捕获（HOT）和一种新形式的纳米控制光聚合。该工具将允许创建一类新的碳纳米管聚合物复合材料，其对材料结构具有前所未有的控制，包括在各种不同的聚合物主体中的取向、分布、缠结和形状。 这些新材料系统的实现将有助于系统地探索有组织的碳纳米管复合材料的机械，热，电性能和结构-性能关系，该项目的更广泛的影响/商业潜力不仅涉及一类新的工程材料的开发，而且还涉及改进现有的纳米制造方法和技术的多陷阱全息光学捕获（HOT）系统。即将开发的新纳米纤维系统将为制造以前不适合工业制造的纳米材料系统开辟新的途径。 能够产生中等体积的材料的系统的开发创建用于系统研究碳纳米管/聚合物复合结构的宏观性质的手段。碳纳米管复合材料的一个潜在市场是作为氧化铟锡（ITO）的替代品。 ITO广泛应用于快速增长的显示器市场和红外光学器件市场。然而，由于铟的高成本和有限的供应，替代的透明导体是非常期望的。 此外，有超过100个已发表的研究小组从事光学捕获，主要用于生物研究，他们将代表HOT方法进步的相当大的市场。 这个市场需要不断改进的技术，并将这些系统纳入复杂的显微镜工具激起了显微镜制造商的兴趣，在主动波前调制设备作为可选的产品配件。
