US 2008/0187996 A1 · Nanofibers, nanofilms and methods of making/using thereof

Abstract

Described herein are compositions for making nanofibers and nanofilms composed of metal oxides, organic polymers, or combinations thereof. Also described herein are methods for making nanofibers and nanofilms where the fibers are formed from a solution having more than one solvent, where the solvents are immiscible. Nanofibers and nanofilms composed of metal oxides, organic polymers or combinations thereof are described. Finally, methods for using the nanofibers and nanofilms are described.

A composition for making a nanofiber comprising:

(a) a metal oxide, a metal oxide precursor, or a combination of metal oxide and metal oxide precursor and
(b) a first solvent and second solvent,
wherein the metal oxide, metal oxide precursor or combination of metal oxide and metal oxide precursor is soluble in the first solvent, the second solvent, or both the first and second solvent and wherein the first solvent and second solvent are immiscible.

A fiber-forming composition comprising:

(a) a metal oxide, a metal oxide precursor or a combination of a metal oxide and a metal oxide precursor;
(b) a polymer or a polymer precursor;
and
(c) a first solvent and second solvent,
wherein the metal oxide, metal oxide precursor, combination of metal oxide and metal oxide precursor, polymer or polymer precursor are soluble in the first solvent, the second solvent, or both the first and second solvent, and the first solvent and second solvent are immiscible.
