Abstract
Official abstract text for this publication.
Disclosed is a method of making high temperature fiber including incorporating an inorganic atom into a polymer precursor fiber to form a modified polymer precursor fiber and converting the modified polymer precursor fiber to a high temperature fiber having a bonded inorganic atom.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of making high temperature fiber comprising incorporating an inorganic species into a polymer precursor fiber to form a modified polymer precursor fiber and converting the modified polymer precursor fiber to a high temperature fiber having a bonded inorganic atom, wherein the polymer precursor fiber comprises polycarbosilanes. 2. The method of claim 1 , wherein the bonded inorganic atom is bound to nitrogen, oxygen, silicon, boron, or carbon. 3. The method of claim 1 , wherein the inorganic atom comprises a lanthanide. 4. The method of claim 3 , wherein the bonded inorganic atom comprises a refractory metal bound to carbon. 5. The method of claim 1 , wherein the inorganic species is incorporated into the polymer precursor fiber by atomic layer deposition (ALD), molecular layer deposition (MLD), sequential vapor infiltration (SVI) or a combination thereof. 6. The method of claim 1 , wherein the polymer precursor fiber comprises an existing inorganic atom. 7. The method of claim 6 , wherein the inorganic species comprises an inorganic atom that is chemically different from the existing inorganic atom. 8. The method of claim 6 , wherein the inorganic species comprises an inorganic atom that is chemically the same as the existing inorganic atom.
