项目摘要

This Small Business Innovation Research (SBIR) Phase I project seeks to develop and commercialize novel monodisperse ceramic membranes and membrane-reactors. Our innovation is based on self-organized anodic alumina with precisely engineered porous structure and previously unattainable pore size (down to1 nm or less), greatly enhanced chemical and thermal stability, and superb mechanical properties. Commercially available anodic alumina membranes have limited practical application due to their fragility, susceptibility to acid and base attack, as well as the lack of membranes with pore size smaller than 100 nm for symmetrical membranes. The proposed approach addresses these limitations by combining innovative synthesis of highly ordered nanoporous anodic alumina with symmetrical porosity, conversion of anodic alumina into polycrystalline ceramic while preserving its morphology, and conformal deposition of functional layers. The proposed technology will enable the fine-tuning of the pore diameter in the ranges from below 1 nm to 200 nm. Deposition of materials inside the nanopores will afford desired functionality. The membranes will target selected applications, such as fuel cell reformers sized for Next Generation Vehicles, integrated mesoscopic power sources for micro-electromechanical systems (MEMS), as well as future portable energy sources.

这个小型企业创新研究(SBIR)第一阶段项目旨在开发新型单分散陶瓷膜和膜反应器并将其商业化。我们的创新是基于自组织阳极氧化铝，具有精确设计的多孔结构和以前无法获得的孔径(降至1 nm或更小)，极大地增强了化学和热稳定性，以及卓越的机械性能。由于氧化铝膜的易碎性、对酸碱的敏感性，以及缺乏孔径小于100 nm的对称膜，商业上可用的氧化铝膜的实际应用受到了限制。该方法通过创新地合成具有对称孔隙率的高度有序的纳米多孔阳极氧化铝，在保持其形貌的同时将其转化为多晶陶瓷，以及保形沉积功能层来解决这些限制。所提出的技术将能够在小于1 nm到200 nm的范围内微调孔径。在纳米孔内沉积材料将提供所需的功能。这些膜将针对特定的应用，例如为下一代汽车量身定做的燃料电池改进器、用于微电子机械系统(MEMS)的集成介观电源以及未来的便携式能源。
