Synergistic Combination of Reduction and Polymerization Reactions to Prepare Silver/Waterborne Polyurethane Nanocomposite for Coating Applications

摘要: Objectives: In this paper, a novel attempt has been made to develop anionic waterborne polyurethane with antibacterial properties. Methods/Analysis: To achieve goal, one-pot synthesis was used incorporate silver nanoparticles into the Waterborne Polyurethane (WPU) via combination of reduction ions and polymerization reactions. This silver/waterborne nanocomposite applied as modifier for preparing antimicrobial viscose fabric enhanced coloration fastness Findings: A bacterial 100% is observed during activity tests nanocomposites both Escherichia coli Candida albicans. Transmission Electron Microscopy (TEM) X-ray Diffraction (XRD) confirm formation Ag in WPU. Scanning (SEM-EDX) Fourier Transform Infrared Spectroscopy (FTIR) were verify presence composites layers. Exploration properties color strength (K/S) colored fabrics also performed. Novelty/Improvement: The obtained results can be considered measure degree interaction between dyes such cationic reactive classes different modified surfaces.
