This Small Business Technology Transfer (STTR) Phase I project focuses on the growth of high quality Boron Nitride Nanotubes (BNNTs). BNNTs have both high thermal conductance that is an order of magnitude higher than aluminum, and also have an electronic bandgap of about 6 eV that makes them an excellent electrical insulator. These unique properties promise many exciting applications. Unfortunately, BNNTs are notoriously difficult to grow, which means that they cannot be produced in the quantities necessary to fulfill industrial needs. The objective of this project is to further advance a recently developed growth technique for high quality BNNTs. If successful, this will allow for a thousand-fold increase in the BNNT growth rate over the standard chemical vapor deposition growth methodology. Furthermore, the grown BNNTs will be used to create composite materials, which will be tested for use as thermally conductive materials in thermal management of electronic systems. The broader impact/commercial potential of this project stems from the successful increase in the growth rate of high quality BNNTs. Heat management of electronic systems is one of the most pressing challenges facing the industry. Most electronics systems use plastic materials both as mounting material and as packaging to electrically isolate the electronic components. However, these materials cause heat bottlenecks that require expensive workarounds and bulky cooling systems. For this reason, a large amount of industrial research is focused on solving these heat management challenges. When the growth rate of BNNTs has been successfully scaled up, and the feasibility of the BNNT composites are established, it will allow for wide scale production of thermally conductive, electrically insulating plastic composite materials. These materials can be used in everything from electric engine controllers to high-efficiency light emitting diode units to alleviate the buildup of heat in electronic systems. Widespread use of BNNT composites will allow for decreased electronic component failure rates, decreased need for bulky cooling systems, etc. In addition, these composites will open up the door for new innovations, such as three-dimensional electronic system architectures.

这个小型企业技术转移（STTR）I阶段项目的重点是高质量的氮化硼纳米管（BNNTS）的增长。 BNNT具有高温电导率，比铝高的数量级，并且具有约6 eV的电子带隙，使它们成为出色的电绝缘体。 这些独特的属性有望许多令人兴奋的应用程序。不幸的是，众所周知，BNNT很难成长，这意味着它们不能以满足工业需求所需的数量生产。 该项目的目的是进一步推进最近开发的高质量BNNT增长技术。如果成功，这将使BNNT增长率比标准化学蒸气沉积生长方法增加一千倍。此外，生长的BNNT将用于创建复合材料，该复合材料将在电子系统的热管理中用作热导电材料。该项目的更广泛的影响/商业潜力源于高质量BNNT的增长率的成功提高。电子系统的热量管理是该行业面临的最紧迫的挑战之一。大多数电子系统都使用塑料材料作为安装材料和包装来电气隔离电子组件。但是，这些材料会导致热瓶颈需要昂贵的解决方案和笨重的冷却系统。 因此，大量的工业研究集中在解决这些热量管理挑战上。当BNNT的生长速率已成功扩大并确定BNNT复合材料的可行性时，它将允许大规模生产热导电，电绝缘塑料复合材料。 这些材料可用于从电动发动机控制器到发射二极管单元的高效率光单元的所有用途，以减轻电子系统中的热量积聚。 BNNT复合材料的广泛使用将允许降低电子组件故障率，减少对笨重的冷却系统的需求等。此外，这些复合材料将为新创新（例如三维电子系统体系结构）打开大门。
