Abstract
A method of producing fibers, includes placing a composition that includes one or more fluoropolymers in the body of a fiber producing device and rotating the device at a speed sufficient to eject material from the fiber producing device to form fluoropolymer microfibers and/or nanofibers.
Claims15
A method of producing fibers, comprising:
- mixing one or more fluoropolymers with a solvent to produce a composition comprising a solution of the one or more fluoropolymers in the solvent;
- placing the composition comprising one or more fluoropolymers into a fiber producing device, the fiber producing device comprising a body comprising a concave cavity and one or more openings in communication with the concave cavity, wherein the composition is placed into the concave cavity of the body;
- rotating the fiber producing device at a speed of at least about 500 rpm, wherein rotation of the fiber producing device causes the composition in the concave cavity of the body of the fiber producing device to be passed from the concave cavity of the body through one or more of the openings to produce microfibers and/or nanofibers comprising one or more of the fluoropolymers;
- and
- collecting at least a portion of the produced microfibers and/or nanofibers;
- wherein the microfibers and/or nanofibers are created without subjecting the fibers, during their creation, to an externally applied electric field.
