This Small Business Innovation Research Phase I project will examine the feasibility to develop effective replacements for fluorochemicals that are widely used in the textile industry to produce soil and stain resistant finishes on clothes, upholstery, carpet and medical textiles. Fluorochemicals, while highly effective, have been shown to be persistent in the environment, bio-accumulative, and have recently been cited by the Environmental Protection Agency as probable carcinogens. Moreover, fluorochemicals and the precursors used to prepare these materials such as perfluorooctanoic acid (PFOA) have been shown to accumulate in human breast tissue and in arctic wildlife. There is a clear need to develop an effective replacement for fluorochemicals that provides the benefits of fluorochemicals but is not bio-accumulative and is not harmful to the environment or people. G3 Technology Innovations will develop novel advanced materials utilizing nanoparticle surface modification methods developed by G3i, to create a superhydrophobic, nano-rough surface in a single-step process. The broader impacts/commercial potential of this project is to eliminate the use of fluorochemicals in water-resistant textile finishes. The novelty of this technology is that it provides a soil and stain resistant finish that is free of fluorochemicals, contains no VOCs, and can be applied to fabric using existing textile finishing equipment in a single-step process. This technology will be highly beneficial to the US textile industry, enabling differentiation from foreign competition. Furthermore, the technology is beneficial to society at large since it virtually eliminates a major source of environmental pollution.

该小型企业创新研究第一阶段项目将研究开发广泛用于纺织行业的含氟化合物的有效替代品的可行性，这些含氟化合物用于在衣服、室内装饰、地毯和医用纺织品上生产防污和防污整理剂。含氟化合物虽然非常有效，但已被证明在环境中具有持久性和生物累积性，并且最近被环境保护局列为可能的致癌物。此外，含氟化合物和用于制备这些材料的前体（例如全氟辛酸（PFOA））已被证明会在人类乳腺组织和北极野生动物中积累。显然需要开发一种有效的含氟化合物替代品，该替代品具有含氟化合物的优点，但不具有生物累积性，并且对环境或人类无害。 G3 Technology Innovations 将利用 G3i 开发的纳米颗粒表面改性方法开发新型先进材料，从而在一步过程中创建超疏水、纳米粗糙表面。该项目更广泛的影响/商业潜力是消除防水纺织品整理剂中氟化物的使用。该技术的新颖之处在于，它提供了一种不含氟化合物、不含挥发性有机化合物的防污防污整理剂，并且可以使用现有的纺织整理设备通过一步工艺应用于织物。这项技术将对美国纺织业非常有利，使其能够在国外竞争中脱颖而出。此外，该技术对整个社会都有好处，因为它实际上消除了环境污染的主要来源。
