NOVELTY - Preparing a composition for pyrolysis to a graphene-ceramic matrix composite involves providing graphite mixed in a thermosettable, liquid preceramic polymer to make a dispersion and providing an energy input to the dispersion to delaminate the graphite to graphene. USE - Method for preparing a composition for pyrolysis to a graphene-ceramic matrix composite. ADVANTAGE - The method enables to prepare a composition that can be pyrolytically converted to a graphene-reinforced ceramic matrix composite. A polysilazane can be used as the preceramic polymer, in some cases providing ammonia or an amine in the process to facilitate delamination of the graphite to graphene. Ceramic, metal, mineral or carbon particulates, platelets, or fibers may be added to the composition to impart enhanced mechanical and/or electrical properties to the finished graphene-reinforced ceramic matrix composites. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: 1. a composition, which comprises a continuous, thermosettable, liquid preceramic polymer component; and a dispersed, in situ-generated graphene component; 2. a method for preparing a composition that can be pyrolyzed to a graphene-ceramic matrix composite, which involves providing a slurry of graphite mixed in a thermosettable, liquid preceramic polymer and applying energy in the form of microwave radiation or a mechanical shear force to delaminate the graphite to graphene; and 3. Graphene-ceramic matrix composite formed by the pyrolysis of the composition formed by the process.
