This Small Business Technology Transfer (STTR) Phase I project will evaluate the technical and commercial feasibility of producing nanotube and nanoparticle "masterbatches" in selected high-performance thermoplastics using specifically tailored POSS components as dispersing agents. Polymer modification with carbon nanotubes and other nanoparticles is the subject of extensive research and interest because of the potential to produce dramatically enhanced mechanical, electrical and thermal properties. Current commercial use of carbon nanotubes in polymers, however, is limited to only a few specialized applications due chiefly to difficulties in obtaining adequate dispersion of the nanoparticles in the polymer matrix, which is critical to achieve the desired properties. Unlike many other nanoparticles, polyhedral oligomeric silsesquioxane (POSS) nanoparticles are easily dispersed in a wide range of polymer matrices. This is achieved by tailoring the chemical structure of the POSS molecule for compatibility with the specific polymer resin. Commercially, conductive, transparent engineering thermoplastic nanocomposites based on POSS/carbon nanotube dispersions could find immediate application in a wide range of high-tech products including antistatic and/or shielding plastics for displays, electronic packaging, computer and business equipment products, and aircraft canopies. The market for conductive plastics alone is estimated at $1 billion for 2005. In addition, a prominent plastics manufacturer has shown interest in commercialization of the POSS masterbatches at the completion of Phase I.

这个小型企业技术转移（STTR）第一阶段项目将评估在选定的高性能热塑性塑料中使用专门定制的POSS组分作为分散剂生产纳米管和纳米颗粒“母粒”的技术和商业可行性。用碳纳米管和其他纳米颗粒修饰聚合物是广泛研究和兴趣的主题，因为有可能产生显着增强的机械，电学和热性能。然而，目前碳纳米管在聚合物中的商业应用仅限于少数专业应用，主要原因是难以在聚合物基体中获得足够的纳米颗粒分散，而这是实现所需性能的关键。与许多其他纳米颗粒不同，多面体低聚硅氧烷（POSS）纳米颗粒易于分散在广泛的聚合物基质中。这是通过剪裁POSS分子的化学结构以与特定聚合物树脂相容来实现的。商业上，基于POSS/碳纳米管分散体的导电透明工程热塑性纳米复合材料可以立即应用于广泛的高科技产品，包括显示器的防静电和/或屏蔽塑料，电子封装，计算机和商业设备产品以及飞机顶篷。2005年，仅导电塑料的市场估计就有10亿美元。此外，一家著名的塑料制造商表示有兴趣在第一阶段完成后将POSS母粒商业化。
