Abstract
A method of forming a preceramic polymer includes treating a silane precursor having a vinyl moiety of ammonia to produce the preceramic polymer. For example, the silane precursor is trichlorovinylsilane. The preceramic polymer may then be cross-linked at a relatively low temperature by using a cross-linking agent.
Claims7
A method of forming a preceramic silazane polymer, comprising:
- mixing tetrahydrofuran as a carrier solvent with a silane precursor that includes trichlorovinylsilane in a ratio of about 10 parts of the tetrahydrofuran to about 1 part of the trichlorovinylsilane;
- treating the silane precursor with ammonia;
- and
- adding a cross-linking agent to the silane precursor, wherein the cross-linking agent is dicumyl peroxide, to initiate cross-linking of the trichlorovinylsilane and produce the preceramic silazane polymer.
