This Small Business Innovation Research (SBIR) Phase I project proposal focuses on providing a feasibilitydemonstration of producing electrospun nanowebs of nanofibers, and combining them with conventionalfilter media to form novel NanoFilter media for specific filtration applications. These applications are wellsuited to address the problems of removal of particles smaller than 3 microns from effluent streams -wheresuperior efficiency of nanowebs in capturing sub-micron particles is very attractive for cost considerationsas well. Initially, the nanofibers will be electrospun from a solution of Nylon 6 in formic acid and laid directly on to a conventional support filter media as a nanoweb. The web architecture will be easily tailored to achieve the desired composite filter performance by varying fiber diameter, fiber orientation, fiber packing fraction within the nanoweb, and the nanoweb thickness. This project will be carried out collaboratively by eSpin Technologies, a small, high-technology start-up company based in Chattanooga, TN, and specializing in providing custom-made electrospun nanofibers, with academic centers and major corporations as its partners. Together they possess the skills and facilities needed to successfully carry out the work under this grant.Nanotechnologies developed in the coming years will form the foundation of significant commercialplatforms. This business will be a key supplier of nanofiber technology which have the potential forcommercial applications in a variety of fields including, filtration: industrial filters, biological separations,ultra pure air and water systems, next generation clean rooms, agriculture and food industries, andmicroelectronic industries.

该小型企业创新研究 (SBIR) 第一阶段项目提案的重点是提供生产纳米纤维电纺纳米网的可行性论证，并将其与传统过滤介质结合形成用于特定过滤应用的新型纳米过滤介质。 这些应用非常适合解决从废水流中去除小于 3 微米颗粒的问题，其中纳米纤维网在捕获亚微米颗粒方面的卓越效率对于成本考虑也非常有吸引力。 最初，纳米纤维将从尼龙 6 的甲酸溶液中静电纺丝，并作为纳米纤维网直接铺在传统的支撑过滤介质上。 通过改变纤维直径、纤维取向、纳米纤维网内的纤维堆积分数和纳米纤维网厚度，可以轻松定制纤维网结构，以实现所需的复合过滤器性能。 该项目将由 eSpin Technologies 合作开展，eSpin Technologies 是一家位于田纳西州查塔努加的小型高科技初创公司，专门提供定制的电纺纳米纤维，其合作伙伴包括学术中心和大公司。他们共同拥有成功开展这项拨款所需的技能和设施。未来几年开发的纳米技术将构成重要商业平台的基础。该业务将成为纳米纤维技术的主要供应商，纳米纤维技术具有在各种领域的商业应用潜力，包括过滤：工业过滤器、生物分离、超纯空气和水系统、下一代洁净室、农业和食品工业以及微电子工业。
