Title
(EN) TEMPLATE-SUPPORTED METHOD OF FORMING PATTERNS OF NANOFIBERS IN THE ELECTROSPINNING PROCESS AND USES OF SAID NANOFIBERS
Abstract
(EN)

The invention relates to a method for producing two- and three-dimensionally structured, microporous and nanoporous webs made up of nanofibers in any form with a very high covering or depositing degree of the fibers by means of a predefined conductive mold (template) as a collector and to the use of the webs according to the invention. The three-dimensional structure formation can be influenced in a directed manner by the deposition density of the nanofibers generated by means of an electrospinning process, which deposition density is adjustable through the accumulation time of the fibers.
