This Small Business Innovation Research Phase I project will develop a process for producing high-aspect ratio boehmite nanoscopic platelets. Boehmite is an inexpensive mineral produced in large volumes as a precursor to alumina catalyst supports. In the project simple and inexpensive methods for modifying the surface of boehmite to render it dispersible in and reactive with a wide variety of polymeric matrices will be developed. Subtly changing the boehmite synthesis conditions and adding morphology-directing compounds to the reaction mixture will achieve the formation of high aspect-ratio boehmite platelets. Particle size and shape will routinely be measured by a combination of x-ray diffraction and light scattering techniques which will, in turn, be verified by atomic force microscopy and transmission electron microscopy. The high aspect ratio boehmite developed in this research project will result in dramatic improvements to the barrier properties of its composites, leading to inexpensive nanocomposite barrier films for packaging, paints and coatings. Mechanical properties of composites with high-aspect ratio boehmite platelets are also expected to improve.

这个小企业创新研究第一阶段项目将开发一种生产高纵横比薄铝石纳米血小板的工艺。薄水铝石是一种廉价的矿物，作为氧化铝催化剂载体的前驱体大量生产。在该项目中，将开发简单而廉价的改性薄水铝石表面的方法，使其可分散在各种聚合物基质中并与之反应。微妙地改变薄水铝石的合成条件，并在反应混合物中加入形态导向化合物，将实现高纵横比薄水铝石血小板的形成。粒子的大小和形状将通过x射线衍射和光散射技术的组合进行常规测量，然后通过原子力显微镜和透射电子显微镜进行验证。在本研究项目中开发的高纵横比薄水铝石将显著改善其复合材料的阻隔性能，从而导致用于包装、油漆和涂料的廉价纳米复合阻隔膜。高纵横比薄铝石薄片复合材料的力学性能也有望得到改善。
