Abstract
New methods for synthesizing boron-modified silazanes, their use as polymer-derived ceramic precursors, and polymer-derived ceramics and composites formed therefrom are disclosed. The polymeric ceramic precursors comprise a boron-modified silazane that is a room temperature liquid-phase polymer comprising a backbone having recurring monomeric repeat units comprising boron-nitrogen bonds. Nanocomposites comprising polymer-derived ceramics and carbon nanotubes are also disclosed.
