| Riassunto: | Заглавие с экрана In this work, electrospun poly(3-hydroxybutyrate) (PHB) scaffolds with a composite filler of magnetite– reduced graphene oxide (Fe3O4–rGO) have been synthesized. The decrease in the fiber diameter enhanced the ductility and mechanical strength of scaffolds. The surface electric potential of PHB/Fe3O4 rGO composite scaffolds increased with increasing fiber diameter owing to a greater number of polar functional groups. The changes in the microfiber diameter did not have any influence on effective piezoresponses of composite scaffolds. The Fe3O4–rGO filler imparted high saturation magnetization (6.67 ± 0.17 emu/g) to the scaffolds. Thus, magnetic PHB/Fe3O4–rGO composite scaffolds both preserve magnetic properties and provide a piezoresponse, whereas varying the fiber diameter offers control over ductility and surface electric potential Текстовый файл |
