Abstract

A number of investigations are described to illustrate the use of small-angle x-ray and neutron scattering to characterize the structures of organic-inorganic composites. The organic phase in these materials is typically a polymer such as poly (dimethylsiloxane), and the inorganic phase a ceramic such as silica or titania (obtained by in-situ hydrolysis and condensation of an organosilane or organotitanate in the usual sol-gel approach). Other inorganic phases of interest include porous materials such as zeolites or Vycor glass. A major goal in such investigations is to correlate the structures of the composites with the synthetic techniques used to prepare them, and with the mechanical properties they exhibit. Carrying out scattering measurements as a function of time can also be used to obtain kinetic results on the sol-gel reactions used to generate the dispersed phase.
