Incorporation of bio-metallic nanoparticles into fiber membranes and their future application

Abstract

This diploma thesis is focused on polymer fibers with incorporated silver and gold biosynthesized nanoparticles prepared by different spinning methods – centrifugal spinning and electrostatic spinning (NanospiderTM technique). Theoretical part offers a brief introduction to a polymer world and introduces certain polymers often used in the spinning applications and their characteristics. Description of fiber spinning methods is included. Experimental part comprises all data about bio-metallic nanoparticles preparation and characterization by Transmission Electron Microscopy (TEM), X-Ray Diffraction (XRD), Atomic Emission Spectroscopy (AES-ICP), Infrared Spectroscopy (FTIR) and size distribution methods. Fibrous samples obtained by spinning methods are characterized by Scanning Electron Microscopy (SEM), TEM and FTIR. The efficiency of used spinning methods is compared and the quality of fibrous samples with incorporated nanoparticles is discussed. Additionally, antimicrobial properties of biosynthesized silver and gold nanoparticles are confirmed by antimicrobial evaluation.
