Appl. No.:

12/689334

Assignee:

Zeus Industrial Products, Inc. - Orangeburg SC

International Classification:

D01F 6/12
D06M 10/00
H05B 7/00

US Classification:

264465, 264127, 26421112, 26421117, 264234

Abstract:

An improved process for forming a PTFE mat is described. The process includes providing a dispersion with PTFE, a fiberizing polymer and a solvent wherein said dispersion has a viscosity of at least 50,000 cP. An apparatus is provided which comprises a charge source and a target a distance from the charge source. A voltage source is provided which creates a first charge at the charge source and an opposing charge at the target. The dispersion is electrostatically charged by contact with the charge source. The electrostatically charged dispersion is collected on the target to form a mat precursor which is heated to remove the solvent and the fiberizing polymer thereby forming the PTFE mat.

Abstract:

In accordance with certain embodiments of the present disclosure, a process for forming a multilayered electrospun composite is provided. The process includes forming a dispersion of polymeric particles, a fiberizing polymer, and a solvent, the dispersion having a viscosity of at least about 50,000 cPs. Nanofibers from the dispersion are electrospun onto a first ePTFE layer. A second ePTFE layer is applied onto the nanofibers to form a composite structure. The composite structure is heated.

Abstract:

Espun material may function as a filtration medium or be put to other uses. The espun material may comprise espun poly(tetrafluoroethylene) (espun PTFE). One or more layers of the espun material may be included. The properties of the espun material can be tailored. For example, a gradient fabric may include espun PTFE. The gradient fabric may include two or more layers of espun PTFE.

US Classification:

623 146, 427 224

Abstract:

A stent or other prosthesis may be formed by encapsulating a scaffold or frame with a polymer coating. The polymer coating may consist of layers of electrospun polytetrafluoroethylne (PTFE). Electrospun PTFE of certain porosities may permit endothelial cell growth within the prosthesis. The stent may be applicable to stents designed for the central venous system, peripheral vascular stents, abdominal aortic aneurism stents, bronchial stents, esophageal stents, biliary stents, or any other stent.
