Abstract
In the present work the production method influence (solution blow spinning and electrospinning) on the structure and properties of the ferroelectric nonwoven materials based on VDF-TeFE copolymer is investigated. It was shown that the nonwoven materials obtained by electrospinning have smooth cylindrical-shaped fibers with a narrow diameter distribution, whereas the nonwoven materials produced by solution blow spinning are characterized by multi-level spatial organization with the fibers having their own advanced morphology. By using DSC and XRD analysis it was found that the nonwoven materials obtained by electrospinning have higher content of the electrically active phases. Also these materials have higher strength owing to their morphological and structural features. It was shown that both types of nonwoven materials are non-toxic. A higher adhesion of stem cells and cells from EA-hy 926 cell line to nonwoven materials produced by solution blow spinning was observed.
