Electrostatic spinning of polyvinyl alcohol and its mixture with silver nanoparticles prepared by biosynthesis

Abstract

This bachelor thesis focuses on the study of biosynthesized silver nanoparticles and electrospinning process poly(vinyl alcohol) and its mixture with prepared nanoparticles. The theoretical part describes partly the preparation and antibacterial properties of silver nanoparticles and partly the process of electrostatic spinning with focus on preparation of poly(vinyl alcohol) fibrous samples. The experimental part aims at characterization how silver nanoparticles are prepared via phytosynthesis and polymeric nanofibers as well as mixture of polymer with nanoparticles via electrospinning method. For characterization of prepared samples, several methods such as electron microscopy, infrared spectroscopy, ultraviolet visible spectroscopy, X-ray diffraction and dynamic light scattering were used. Silver nanoparticles were successfully synthetized via phytosynthesis. Then, electrostatic spinning of poly(vinyl alcohol) and its mixture with prepared silver nanoparticles was evaluated as successful and repeatable.
