Silver Nanoparticles by Amino-Terminated Hyperbranched Polymer : Characterization and Antimicrobial Property on Cotton


Article Preview

A hyperbranched polymer (HBP-NH2) acting as a reducing agent and stablizer agent has been synthesized to investigate the stability of silver nanoparticles antimicrobial agent, which were prepared in a hyperbranched polymer matrix by a reaction with silver nitrate solution. The antimicrobial agents generated were characterized by different spectroscopic and analytical techniques such as DLS, TEM and UV-vis, which confirm the formation of well-dispersed silver nanoparticles with average size around 12.0 nm. Furthermore, antimicrobial and mechanical properties of nanosilver treated cotton fabrics were investigated. The results showed that stable silver nanoparticles collide solution with 12 nm, applied on cotton fabric under certain condition, could produce ideal antibacterial rate over 94% against both Escherichia coli (E.coli) and Staphylococcus aureus (S.aureus) even after 50 consecutive washings.
