In this project, the concept of charge driven self assembly (CDSA) will be tested as a route for the making of nanocomposite materials consisting of one acid functionalized polymer and silica (or functionalized silica) nanoparticles. The properties of membranes made of these nanocomposites will be examined in view of their possible application in Polymer Electrolyte Membrane Fuel Cells (PEMFC). The polymer matrixes under study will be from the series of sulfonic acid functionalized materials developed over the last few years in our laboratory in collaboration with scientists of the National Research Council (ICPET-Ottawa). The work will include some studies of the suspension stabilisation of a variety of silica and acid functionalized silica nanoparticles. CDSA will also be applied in the layer by layer self-assembly of multilayer thin films which may lead to a new technique of membrane preparation. This new technique should be rather easily scaled-up to commercial scale.

在这个项目中，电荷驱动自组装（CDSA）的概念将被测试作为一种路线，用于制造纳米复合材料组成的一个酸官能化聚合物和二氧化硅（或官能化二氧化硅）纳米粒子。由这些纳米复合材料制成的膜的性能将被检查，鉴于其在聚合物电解质膜燃料电池（PEMFC）的可能应用。所研究的聚合物基质将来自我们实验室与国家研究理事会（ICPET-渥太华）的科学家合作在过去几年中开发的一系列磺酸官能化材料。这项工作将包括各种二氧化硅和酸官能化二氧化硅纳米粒子的悬浮稳定的一些研究。CDSA还可应用于多层薄膜的层层自组装，这可能导致一种新的膜制备技术。这种新技术应该很容易扩大到商业规模。
