Abstract
Tin-containing carbon fibers may be produced by centrifugal spinning of a precursor composition that includes a base polymer and a tin-containing compound. The produced fibers are heated at a temperature sufficient to convert at least a portion of the base polymer in the collected fibers into carbon fibers comprising tin.
Claims18
A method of producing tin-containing carbon fibers, comprising:
- dispersing tin (II) sulfide particles in a solvent;
- dissolving a base polymer in the solvent to form a mixture of the base polymer and the tin (II) sulfide particles, wherein the base polymer is convertible into carbon fibers when heated;
- placing the mixture into a body of a fiber producing device, the body comprising one or more openings;
- rotating the fiber producing device at a speed of at least about 500 rpm, wherein rotation of the fiber producing device causes the polymer in the body to be passed through one or more openings to produce microfibers and/or nanofibers comprising the polymer;
- collecting at least a portion of the produced microfibers and/or nanofibers;
- and
- heating the collected fibers at a temperature sufficient to convert at least a portion of the base polymer in the collected fibers into carbon fibers comprising tin.
