Electrostatic field-assisted alignment of electrospun nanofibres

This paper describes an electrostatic field-assisted assembly technique com bined with an electrospinning process used to position and align individual nanofibres (NFs) on a tapered and grounded wheel-like bobbin. The bobbin i s able to wind a continuously as-spun nanofibre at its tip-like edge. The a lignment approach has resulted in polyethylene oxide-based NFs with diamete rs ranging from 100-300 nm and lengths of up to hundreds of microns. The re sults demonstrate the effectiveness of this new approach for assembling NFs in parallel arrays while being able to control the average separation betw een the fibres.
