초록

A method of manufacturing a ceramic coated fiber comprises heat treating an activated carbon coated fiber containing a ceramic precursor, to form a ceramic coated fiber.

대표청구항 ▼

1. A method of manufacturing a ceramic coated fiber, the method comprising: infiltrating an activated carbon coated fiber with a ceramic precursor, the infiltration being carried out at room temperature and comprising immersing the activated carbon coated fiber in a solution comprising the ceramic precursor in a volatile solvent;after the infiltrating, removing an excess of the ceramic precursor by washing with ethanol; andafter the removing, heat treating the activated carbon coated fiber containing the ceramic precursor to form a ceramic coated fiber. 2. The method of claim 1, wherein the heat treating comprises: a first heating at a first temperature of at least 250 ° C., to cure the ceramic precursor, anda second heating at a second temperature of at least 400° C. in an oxidizing atmosphere to remove the carbon. 3. The method of claim 2, wherein the first heating is in an inert atmosphere. 4. The method of claim 2, wherein the ceramic comprises TiO2 and/or TiON having an anatase structure. 5. The method of claim 4, wherein the ceramic precursor further comprises a nitrogen or sulfur dopant. 6. The method of claim 5, wherein the nitrogen source is tetramethylammonium hydroxide. 7. The method of claim 2, further comprising: contacting the ceramic coated fiber with a compound containing silver; and a third heating of the ceramic coated fiber. 8. The method of claim 2, further comprising: contacting the ceramic coated fiber with a compound containing palladium;a third heating of the ceramic coated fiber; anda fourth heating of the ceramic coated fiber in an atmosphere comprising H2. 9. The method of claim 2, wherein the ceramic comprises crystalline ceramic and has a BET surface area of at least 50 m2/g. 10. The method of claim 2, wherein the ceramic comprises at least one member selected from the group consisting of TiO2, TiON, TiOS, Al2O3, ZrO2, and MgO. 11. The method of claim 2, where the oxidizing atmosphere is pure O2. 12. The method of claim 2, where the oxidizing atmosphere is air. 13. The method of claim 2, where the first temperature is from 250° C. to 600° C. 14. The method of claim 13, where the first temperature is from 250° C. to 400° C. 15. The method of claim 2, wherein the second temperature is from 400° C. to 1000° C. 16. The method of claim 1, further comprising, prior to the heat treating, hydrolyzing the ceramic precursor. 17. The method of claim 16, where hydrolyzing the ceramic precursor comprises exposing the ceramic precursor to air moisture. 18. A method for manufacturing an intermediate for the fabrication of ceramic coated fibers, the method comprising infiltrating an activated carbon coated fiber with a ceramic precursor, the infiltration being carried out at room temperature and comprising immersing the activated carbon coated fiber in a solution comprising the ceramic precursor in a volatile solvent;after the infiltrating, removing an excess of the ceramic precursor by washing with ethanol; andafter the removing, heating the activated carbon coated fiber containing the ceramic precursor to cure the precursor.
