NMR Studies of Polymer Nanocomposites
Abstract
Methods developed and refined to characterize ion and molecular transport process in disordered media are described. The primary tool is pulsed field gradient NMR. A static field gradient method was developed which makes possible variable pressure diffusion measurement, and the application to the important fuel cell membrane NAFION constitute the first results of their kind ever published. Standard ambient pressure results for lithium ion conducting polymer electrolytes containing nanoscopic silica are included, as well as the description of a novel scheme to produce highly conducting polymer electrolytes by magnetic field alignment of the polymer chains. Fuel cell membranes developed by collaborators at Wright-Patterson Air Force Base were also investigated.
