Patents by Inventor Byunggwang Jo

Byunggwang Jo has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8647090
    Abstract: An injection nozzle for electrospinning including a first nozzle body and a second nozzle body detachably coupled with each other and nozzle members inserted in the first and second nozzle bodies and an electrospinning device using the nozzle. The electrospinning device basically performs air electrospinning wherein a source liquid for fiber is injected together with air while the source liquid for fiber is discharged through the nozzle members, and pure electrospinning without air injection can be efficiently carried out by separating the second nozzle body in such a manner that the lower ends of the nozzle members are exposed for a predetermined length or more. Therefore, according to the present invention, pure electrospinning, air electrospinning or hot air electrospinning may be selectively carried out.

  • Patent number: 8550798
    Abstract: The present invention relates to an injection nozzle for electrospinning including a nozzle body and an air jacket member detachably coupled with each other, and needle members coupled to the bottom surface of the node body via injection holes of the air jacket member. The electrospinning device basically performs air electrospinning for injecting a fiber solution together with air while discharging the fiber solution through the needle members, and the needle members are exposed at the ends thereof by a length long enough to carry out error-free pure electrospinning without air injection if the air jacket member is separated. Therefore, pure electrospinning or air electrospinning can be selectively carried out.
