Abstract
Electrospinning apparatus and method for producing multi-dimensional structures such as one-dimensional continuous yarns, two-dimensional mats and three-dimensional cotton-like fluffy scaffolds is disclosed. Further, electrospinning apparatus and method with single collector geometry for producing multi-dimensional structures and core-sheath yarns are disclosed.
Claims15
A method of producing a two or three-dimensional scaffold by electrospinning, comprising:
- a. loading at least one fiber source at a first potential with solution formulation or melt;
- b. placing a rotatable collector unit adjacent to the fiber source at a second potential;
- c. configuring the collector unit comprising a plurality of electrodes connected at one end and mounted with tines at the other end to form an open structure;
- and
- d. depositing fiber from the source into the collector unit using the potential difference to generate a scaffold.
