Ultrafine Fibers of Poly-(3-Hydroxybutyrate) with Zinc–Tetraphenylporphyrin Obtained by Electrospinning

Influence of Processing Methods on the Mechanical Behavior of Poly‐3‐hydroxybutyrate Nonwoven Scaffolds

“…The incorporation of TPP complexes into solution had a significant effect on the fiber morphology, which subsequently provided the increased tensile strength and elongation at break. According to previous works of the authors, [ 7,9 ] the incorporation of 1% wt. of complex of the TPP with zinc (ZnTPP) increased the electrical conductivity and reduced viscosity of the molding solution.…”

“…and 5% wt., respectively. [7,9] Nonwoven mats were obtained by a single-capillary (diameter of 0.1 mm) laboratory facility (EFV-1, Russia). [13] The conditions of ES were as follows: the voltage was in the range of 19-20 kV and the gap between electrodes was in the range of 200-210 mm.…”

“…[6] For several applications the scientists develop functional nanofibers, which contain specific compounds like nanoparticles, carbon nanotubes, catalysis, enzymes, tetraphenylporphyrin (TPP) complexes with metals, etc. [7] It is known that the chemical composition of polymer solution [3] and different types of treatment (ozone in particular) [8] directly influence on the properties of PHB nonwoven mats, but nevertheless there is insufficient information on mechanical performance of the materials in the terms of future application as ECM in the biomedical fields.…”
