Abstract

A cellular material includes a continuous solid phase including an ordered ceramic material, the solid phase having a solid core including the ordered ceramic material. A composition for forming a cellular material includes: a first UV curable pre-ceramic monomer; a second UV curable pre-ceramic monomer; and a photoinitiator. A method of forming at least one ceramic waveguide includes: securing a volume of a composition including a UV curable pre-ceramic monomer; exposing the composition to a light source to form at least one polymer waveguide including a pre-ceramic material; and converting the pre-ceramic material of the polymer waveguide to a ceramic material to form a ceramic waveguide.

Dependent claims

A composition for forming an ordered ceramic material, the composition comprising:

a first UV curable pre-ceramic monomer comprising two or more groups selected from the group consisting of C═X double bonds, C≡X triple bonds, and combinations thereof, X being selected from the group consisting of C, N, and O, the first UV curable pre-ceramic monomer comprising at least one non-carbon atom in a main chain and/or a side chain, and the non-carbon atom being selected from the group consisting of Si, B, Al, Ti, Zn, P, and Ge;
a second UV curable pre-ceramic monomer comprising two or more groups selected from the group consisting of thiol groups, hydroxyl groups, amine groups, and combinations thereof, the second UV curable pre-ceramic monomer further comprising at least one non-carbon atom in a main chain and/or a side chain, and the non-carbon atom being Si;
and
a photoinitiator.
