Abstract
Embodiments of the present disclosure provide electrospinning devices, methods of use, uncompressed fibrous mesh, and the like, are disclosed.
Claims30
An electrospinning apparatus, comprising
- a device that a fiber is drawn from, wherein the tip of the device from where the fiber is drawn is at a first potential, and
- a structure that includes a plurality of conductive probes, wherein each probe has a distal end, wherein a portion of each probe extends from a non-conductive surface of the structure, wherein a first set of the distal ends are recessed relative to a second set of distal ends, wherein the first set and the set of distal ends form a first boundary of a target volume, wherein a second boundary of the target volume is not bound by the distal ends of the plurality of the probes, wherein the device is positioned adjacent the second boundary, wherein the conductive probes are at second potential, wherein there is a potential difference between the first potential and the second potential that causes the fiber to be directed to the target volume through the second boundary.
A method of forming an uncompressed fibrous mesh, comprising:
- applying a potential difference between a tip of a device and a plurality of conductive probes on a structure, wherein each probe has a distal end, wherein a portion of each probe extends from a non-conductive surface of the structure, wherein a first set of the distal ends are recessed relative to a second set of distal ends, wherein the first set and the set of distal ends form a first boundary of a target volume, wherein a second boundary of the target volume is not bound by the distal ends of the plurality of the probes;
- drawing a fiber from the tip towards the target volume through the second boundary;
- and
- forming the uncompressed fibrous mesh in the target volume.
1 more element
A structure, comprising:
- an uncompressed fibrous mesh including a fiber, wherein the uncompressed fibrous mesh has a volume that is about 50 to 1800 cm3, wherein the fiber occupies about 5 to 20% of the volume of the uncompressed fibrous mesh.
