SBIR Phase II: Carbon Nano Composite Filtration Media

这个小企业创新研究二期项目将制造自组装的纳米复合材料积木，由碳纳米管在宏观支撑上组成。第一阶段展示了附着在金属网上的高质量长纳米管的生长。该载体催化了无烟纳米管分散均匀结构的生长。不需要额外的处理。传统的制造工艺可以将复合材料转化为在纳米尺度上传输质量、电荷和应力的过滤器、电极和结构。纳米管保持有序，并以电气和机械方式连接。产生了紧密的固-气和固-液接触，并伴随着高传输率。与多孔纳米介质不同，孔径可以与纳米管直径无关，允许快速进入其表面。第二阶段的产品将是具有前所未有的过滤效率和低能源成本的微过滤介质。碳纳米管具有增强的单收集器效率和相当高的表面积与体积比。这些优势产生了巨大的价值。这家工业合作伙伴已承诺在初步测试和市场拉动的基础上为低能耗、高成本效益的分离技术提供第三阶段资金。这家工业合作伙伴致力于纳米技术和所支持的纳米复合材料的巨大物理性能。

This Small Business Innovation Research Phase II project will make self-assembled, nanocomposite building blocks, composed of carbon nanotubes on a macroscopic support. Phase I demonstrated the growth of high quality, long nanotubes, adhered to a metal mesh. The support catalyzes the growth of a dispersed uniform structure of sootfree nanotubes. Additional processing is not required. Traditional manufacturing processes can convert the composite into filters, electrodes, and structures that transport mass, charge, and stress on nanometer scales. The nanotubes remain organized and connected electrically and mechanically. Intimate solid-gas and solid-liquid contact accompanied by high transport rates result. Unlike porous nanoscale media, the pore size can be independent of the nanotube diameter, allowing rapid access to their surface.The Phase II product will be microfiltration media with unprecedented filtration efficiency and low energy cost. Carbon nanotubes have enhanced single-collector efficiencies and substantially high surface to volume ratios. These advantages produce enormous, pound-for-pound value. The industrial partner has committed Phase III funding based on initial testing and market pull for low-energy, cost-effective separation technology. The industrial partner is committed to nanoscale technologies and the tremendous physical properties of the supported nanocomposites.
