This Small Business Innovation Research Phase I Project addresses the fabrication and characterization of unprecedented high performance and low cost ceramic membranes - Bendable Ceramic Nanowire Membranes. Membrane-based separation and filtration is a significant part of modern industries. Organic polymer membranes, due to their low manufacture cost and flexible feature, are dominating these markets. Ceramic membranes, despite their intrinsically superior properties, have not been widely adopted due to their high manufacture cost and rigid structures. In this program, Novarials will apply a novel fabrication strategy to make next-generation ceramic membranes based on high quality and low cost ceramic nanowires. These ceramic membranes (1) will be as bendable and flexible as polymer membranes so that they can be integrated into spiral wound systems to achieve high membrane packing density which is 5 to 10 times that of conventional ceramic membranes; (2) will be manufactured at low cost which is 10~20% of conventional ceramic membranes; (3) will be pure ceramic without organic additives, and thus pertain all the superior properties of ceramic materials; (4) will posses nanosized pore of 2 to 100nm in diameter for ultrafiltration where flexible glass fiber membranes failed.These ceramic nanowire membranes will be a disruptive technology in membrane industry. The unprecedented combination of many advantages of the ceramic membranes including flexibility and bendability, low manufacture cost, high stability to temperature, chemical inertness to acids, bases and chlorine, long operation life, as well as nanosized pores, will make them quickly penetrate into the current markets of conventional ceramic membranes. In addition, the ceramic membranes will be a strong competitor to current organic polymer membrane-dominated markets and a high potential candidate for new applications where conventional ceramic membranes failed due to high cost and where polymer membranes failed due to low stability.This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).

这个小型企业创新研究第一阶段项目致力于制造和表征前所未有的高性能和低成本陶瓷膜-可弯曲陶瓷纳米线膜。膜分离与过滤是现代工业的重要组成部分。有机聚合物膜由于其低廉的制造成本和灵活的特性，在这些市场中占据主导地位。陶瓷膜虽然具有优良的性能，但由于制造成本高、结构刚性等原因，尚未得到广泛应用。在这个项目中，Novarials将采用一种新的制造策略，以高质量和低成本的陶瓷纳米线为基础，制造下一代陶瓷膜。这些陶瓷膜(1)将像聚合物膜一样可弯曲和柔性，因此它们可以集成到螺旋缠绕系统中，以实现高膜包装密度，这是传统陶瓷膜的5到10倍；(2)生产成本低，为传统陶瓷膜的10~20%；(3)将陶瓷纯化，不含有机添加剂，具有陶瓷材料的所有优越性能；(4)将具有2 - 100nm直径的纳米级孔，用于柔性玻璃纤维膜失效的超滤。这些陶瓷纳米线膜将成为膜工业的一项颠覆性技术。陶瓷膜的柔韧性和可弯曲性、低制造成本、高温度稳定性、对酸、碱、氯的化学惰性、长使用寿命以及纳米级孔隙等诸多优点前所未有地结合在一起，将使其迅速渗透到当前传统陶瓷膜的市场中。此外，陶瓷膜将成为当前有机聚合物膜主导市场的有力竞争者，并且在传统陶瓷膜因高成本而失败和聚合物膜因低稳定性而失败的新应用领域具有很高的潜力。该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。
