Resin formulations for polymer-derived ceramic materials

A ceramic structure produced by polymerization, 3D printing, and thermal treatment of a preceramic resin formulation comprising:

• (a) first molecules comprising two or more C═X double bonds, two or more C≡X triple bonds, or at least one C═X double bond and at least one C≡X triple bond, wherein X is selected from the group consisting of C, S, N, O, and combinations thereof, and wherein said first molecules further comprise at least one non-carbon atom selected from the group consisting of Si, B, Al, Ti, Zn, P, Ge, S, N, O, and combinations thereof;
• (b) second molecules comprising R—Y—H, wherein R is an organic group or an inorganic group, wherein R is Si for at least one of said second molecules, and wherein Y is selected from the group consisting of S, N, O, and combinations thereof;
• (c) a photoinitiator;
• (d) a free-radical inhibitor;
• and
• (e) a 3D-printing resolution agent.

A method of making a ceramic structure, said method comprising:

• (i) obtaining a preceramic resin formulation ;
• (ii) polymerizing and 3D-printing said preceramic resin formulation to generate a preceramic polymer;
• and
• (iii) thermally treating said preceramic polymer to produce a ceramic structure, wherein said preceramic resin formulation comprises:
• (a) first molecules comprising two or more C═X double bonds, two or more C≡X triple bonds, or at least one C═X double bond and at least one C≡X triple bond, wherein X is selected from the group consisting of C, S, N, O, and combinations thereof, and wherein said first molecules further comprises at least one non-carbon atom selected from the group consisting of Si, B, Al, Ti, Zn, P, Ge, S, N, O, and combinations thereof;
• (b) second molecules comprising R—Y—H, wherein R is an organic group or an inorganic group, wherein R is Si for at least one of said second molecules, and wherein Y is selected from the group consisting of S, N, O, and combinations thereof;
• (c) a photoinitiator;
• (d) a free-radical inhibitor;
• and
• (e) a 3D-printing resolution agent.
