## Abstract A novel technique was developed to control the deposition of electrospun polyurethane fibers using a silicone collector substrate patterned with soft lithography. This method can be used to control selective fiber deposition with broad pattern dimensions (50โ500โยตm) over a large area. T
A novel aqueous fluorine-containing polyurethane was prepared with a hydrophobic macromonomer of a perfluoroalkyl group. Two representative properties of the polyurethane, initial particle diameter dispersed in water and surface free energy of coating films, were investigated. The macromonomer was s
