Abstract
Superelastic conductive fibers, and more particularly, sheath-core fibers for superelastic electronics, sensors, and muscles, and a process for fabricating of highly stretchable sheath-core conducting fibers by wrapping fiber-direction-oriented conductive nanofiber sheets on stretched rubber fiber cores.
Claims26
A method of producing a superelastic conductive fiber comprising:
- (a) selecting a reversibly stretchable fiber core;
- (b) stretching the stretchable fiber core;
- (c) wrapping one or more layers of nanofiber sheet on the stretchable fiber core while it is stretched, wherein
- (i) the wrapping results in wrapped layers of the one or more layers of nanofiber sheets around the stretchable fiber core, and
- (ii) the orientation of nanofibers in at least one of the one or more nanofiber sheets is parallel to the stretchable fiber core;
- (d) releasing the nanofiber wrapped stretchable fiber core, and
- (e) restretching the nanofiber wrapped stretchable fiber core to form the superelastic conductive fiber in stretched state.

A superelastic conductive fiber comprising
- (a) a reversibly stretchable fiber core;
- and
- (b) one or more layers of nanofiber sheets wrapped on the stretchable fiber core, wherein
- (i) the one or more layers of nanofiber sheets were wrapped on the stretchable fiber core while the reversibly stretchable fiber core was in the stretched position,
- (ii) there are wrapped layers of the one or more layers of nanofiber sheets wrapped around the stretchable fiber core, and
- (iii) the orientation of the nanofibers in at least one of the one or more nanofiber sheets is parallel to the stretchable fiber core.
