SILICON-BASED POLYMER-DERIVED CERAMIC COMPOSITES COMPRISING H-BN NANOSHEETS

摘要

Polymer-derived ceramic composites are described herein. The composites are formed using hexagonal boron nitride nanosheet-functionalized silicon-based ceramic precursor polymers. The composites a matrix of a polymer-derived ceramic and hexagonal boron nitride nanosheets embedded therein. Silicon-derived ceramic precursors such as polysilazane and/or polysiloxane are used to create improved SiCN and/or SiOC ceramic composites.
