Paper Title:
Studies in Mesoporous Silicates: Impedance Measurements on SBA-15 Loaded with Sulfonated-Polystyrene and Nafion with SBA-15 Filler
  Abstract

An organic-inorganic composite was formed by cross-linking polystyrene (PS) into a SBA-15-type mesoporous silica (SBA/PS). The SBA-15/PS reacted with sulfuric acid according to published methods to sulfonate the benzene rings of the styrene (SBA-15/PS/SO3). These two latter solids were investigated by TGA/MS to determine stability and decomposition mechanisms. Complex impedance measurements at 10-105 Hz were taken on (SBA-15/PS/SO3) and Nafion cast films loaded with SBA-15 at a level of 1-10%, and similar films with SBA-15/PS/SO3 in hopes that the mesoporous solids might impart desirable properties on the Nafion.
