SBIR Phase I: Eliminating the use of Fluorochemicals in Textile Applications: Superhydrophobic Surfaces via Surface Modified Nanoparticles.

这个小型企业创新研究第一阶段项目将研究开发有效替代氟化学品的可行性。氟化学品广泛用于纺织工业，用于生产衣服、室内装潢、地毯和医用纺织品上的防污和防污饰面。氟化学品虽然非常有效，但已被证明在环境中具有持久性和生物蓄积性，最近被环境保护局列为可能的致癌物。此外，氟化学品和用于制备这些材料的前体，如全氟辛酸（PFOA），已被证明可在人类乳房组织和北极野生动物中积累。显然需要开发一种有效的氟化学品替代品，既能提供氟化学品的好处，又不会产生生物蓄积性，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，在单步工艺中创建超疏水纳米粗糙表面。该项目的更广泛影响/商业潜力是消除在防水纺织品整理中使用含氟化学品。这项技术的新颖之处在于，它提供了一种不含氟化学品、不含挥发性有机化合物（voc）的抗污和抗污整理，可以使用现有的纺织整理设备在单步过程中应用于织物。这项技术将对美国纺织业非常有利，使其在与外国竞争中脱颖而出。此外，这项技术对整个社会都是有益的，因为它几乎消除了环境污染的主要来源。

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.
