Described herein are portable apparatuses and methods of creating fibers such as microfibers and nanofibers. The methods described herein employ accelerated air to impact fine jets created from polymer solutions going through individual tracks or channels within an exit die. Apparatuses that may be used to create fibers are also described.

Handheld/portable apparatus for the production of fine fibers

A novel lithium battery cathode, a lithium ion battery using the same and processes and preparation thereof are disclosed. The battery cathode is formed by force spinning. Fiber spinning allows for the formation of core-shell materials using material chemistries that would be incompatible with prior spinning techniques. A fiber spinning apparatus for forming a coated fiber and a method of forming a coated fiber are also disclosed.

Lithium battery cathode

Described herein are portable apparatuses and methods of creating fibers, such as microfibers and nanofibers. The methods discussed herein employ centrifugal forces to transform material into fibers. Portable apparatuses that may be used to create fibers are described.

Handheld/portable apparatus for the production of microfibers, submicron fibers and nanofibers

Described herein is the application of centrifugal spinning to provide a flexible mechanoluminescent material composed of rare earth metal doped fibers. Rare earth metal doped fibers are formed, in one embodiment, by centrifugal spinning.

Method of producing mechanoluminescent fibers

A method of producing doped carbon fibers, doped systems to prepare graphene-fiber hybrid structures, or doped carbon nanostructures, includes forming doped polymer precursors and decomposing at least a portion of the polymeric precursors to form carbon fibers. The decomposition may be accomplished by treating the doped polymer precursors with acid vapor from an aqueous acid solution at a temperature of less than 250&#xb0; C.

Method of preparing doped and/or composite carbon fibers

Therapeutic pen support

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.

Methods for the production of fluoropolymer fibers

A method of producing carbon fiber, yarns, and nonwoven carbon fiber cloths, includes forming suitable polymeric precursor microfibers and/or nanofibers using a centrifugal spinning process and decomposing at least a portion of the polymeric precursor fibers to form carbon fibers. The decomposition may be accomplished by treating the polymeric precursor fibers with acid vapor from an aqueous acid solution at a temperature of less than 250&#xb0; C.

Method of preparing carbon fibers

Apparatuses and methods for the production of superfine fibers.

Superfine fiber creating spinneret and uses thereof

A method of forming a composite of embedded nanofibers in a polymer matrix is disclosed. The method includes incorporating nanofibers in a plastic matrix forming agglomerates, and uniformly distributing the nanofibers by exposing the agglomerates to hydrodynamic stresses. The hydrodynamic said stresses force the agglomerates to break apart. In combination or additionally elongational flow is used to achieve small diameters and alignment. A nanofiber reinforced polymer composite system is disclosed. The system includes a plurality of nanofibers that are embedded in polymer matrices in micron size fibers. A method for producing nanotube continuous fibers is disclosed. Nanofibers are fibrils with diameters of 100 nm, multiwall nanotubes, single wall nanotubes and their various functionalized and derivatized forms. The method includes mixing a nanofiber in a polymer; and inducing an orientation of the nanofibers that enables the nanofibers to be used to enhance mechanical, thermal and electrical properties. Orientation is induced by high shear mixing and elongational flow, singly or in combination. The polymer may be removed from said nanofibers, leaving micron size fibers of aligned nanofibers.
