Latest Patents

Han's latest patents focus on methods for electrospinning hydrophobic coaxial fibers into superhydrophobic and oleophobic coaxial fiber mats. These methods involve the use of an electrospinning coaxial nozzle that comprises a core outlet coaxial with a sheath outlet. The process includes ejecting an electrospinnable core solution from the core outlet while simultaneously ejecting a hydrophobic sheath solution from the sheath outlet. The hydrophobic sheath solution surrounds the core solution, and a voltage is applied between the nozzle and a collection plate. This voltage induces a jet of the core solution, which is surrounded by the hydrophobic sheath solution, to travel to the collection plate, forming a hydrophobic coaxial fiber. The collection of this fiber results in the creation of a superhydrophobic coaxial fiber mat.
