Silica fillers small-angle scattering

Small-angle scattering techniques have been applied to polysiloxane materials. One important example is the characterization of fillers introduced into polysiloxane elastomers, or the reverse, the incorporation of such elastomers into ceramic matrices (in both cases to improve mechanical properties). - Another example is characterization of the anisotropy induced by strain in silica-PDMS composites. Chapter 9 describes some of this work. Elastic neutron scattering can be illustrated by the characterization of polysiloxane blends, and quasielastic neutron scattering by studies of the dynamics of PDMS. There have also been Monte Carlo calculations of PDMS particle scattering functions, including how they varied with chain length, chain structure, and temperature. ...
