In polymer nanocomposites the polymer chains are confined to the nanoscale (i.e. 1-10 nm dimensions). The properties of nanocomposites are different from those obtained by simple mixing the polymeric and the inorganic phases. Polymer nanocomposites have many potential applications, including fire retardant coatings, transparent abrasion resistant coatings, synthesis of uniform microporous silica powders for chromatography columns, microelectronics and nonlinear optics. The properties of those nanocomposites are related to the morphology and previous work for characterizing it was performed using XPS and ESI-TEM [7]. In this paper SAXS characterization of silica/polymethylmethacrylate (PMMA) nanocomposite using three different types of nanosilica particles is presented.
