A Model for the Nanodomains in Polymer-Derived SiCO

The polymer‐based synthesis of ceramics such as SiCO (and SiCN) leads to the incorporation of significant amounts of carbon into their molecular structure. A key feature of the nanostructure of these polymer‐derived ceramics is the revelation of persistent, 1–5 nm size domains by small‐angle X‐ray scattering. Here we present a model for these nanodomains, which is consistent with the nuclear magnetic resonance (NMR) data and with the...
