Abstract

In an embodiment, a method includes producing a mixed feedstock of at least three halogenated monomer feedstocks. A first of the at least three halogenated monomer feedstocks includes an SP3 carbon, a second of the at least three halogenated monomer feedstocks includes an SP2 carbon, and a third of the at least three halogenated monomer feedstocks includes at least two SP1 carbons. The method further includes producing a polyorbital-hybrid pre-ceramic polymer comprising the SP1 carbons, the SP2 carbon, and the SP3 carbon. The polyorbital-hybrid pre-ceramic polymer is produced by reducing the mixed feedstock such that one or more halogen atoms are removed from the mixed feedstock. The method also includes fabricating the polyorbital-hybrid pre-ceramic polymer into a greenware form and producing a polyorbital-hybrid ceramic carbon comprising the SP1 carbons, the SP2 carbon, and the SP3 carbon. The polyorbital-hybrid ceramic carbon is produced by thermolyzing the polyorbital pre-ceramic polymer.

First claim

The invention claimed is:

1. A method, comprising:
producing a mixed feedstock of at least three halogenated monomer feedstocks, wherein a first of the at least three halogenated monomer feedstocks includes an SP3 carbon, a second of the at least three halogenated monomer feedstocks includes an SP2 carbon, and a third of the at least three halogenated monomer feedstocks includes at least two SP1 carbons;
producing a polyorbital-hybrid pre-ceramic polymer comprising the SP1 carbons, the SP2 carbon, and the SP3 carbon, wherein the polyorbital-hybrid pre-ceramic polymer is produced by reducing the mixed feedstock such that one or more halogen atoms are removed from the mixed feedstock;
fabricating the polyorbital-hybrid pre-ceramic polymer into a greenware form; and
producing a polyorbital-hybrid ceramic carbon comprising the SP1 carbons, the SP2 carbon, and the SP3 carbon, wherein the polyorbital-hybrid ceramic carbon is produced by thermolyzing the polyorbital pre-ceramic polymer.

2. The method of claim 1 , wherein the first of the at least three halogenated monomer feedstocks comprises chloroform.

3. The method of claim 1 , wherein the second of the at least three halogenated monomer feedstocks comprises 3,3,3-trichloropropene.

4. The method of claim 1 , wherein the third of the at least three halogenated monomer feedstocks comprises propargyl trichloride.

5. The method of claim 1 , wherein:
the mixed feedstock comprises respective first percentages of the SP1 carbons, the SP2 carbon, and the SP3 carbon;
the polyorbital-hybrid pre-ceramic polymer comprises respective second percentages of the SP1 carbons, the SP2 carbon, and the SP3 carbon; and
the respective first percentages are approximately equal to the respective second percentages.

6. The method of claim 1 , wherein the polyorbital-hybrid preceramic polymer is thermolyzed within a temperature range of 100 degrees Celsius to 900 degrees Celsius.

7. The method of claim 1 , wherein the mixed feedstock further comprises one of a Group III p-type donor or a Group IV n-type donor such that the polyhybrid orbital ceramic carbon comprises a p-type doping or an n-type doping.

8. The method of claim 7 , wherein the Group III p-type donor comprises boron trichloride.

9. The method of claim 7 , wherein the Group IV n-type donor comprises phosphorus trichloride.

10. The method of claim 1 , wherein the polyorbital-hybrid pre-ceramic polymer is produced without using a laser.
