Copper nanoparticles in glycerol-polyvinyl alcohol matrix: In situ preparation, stabilisation and antimicrobial activity
Original language description
Herein, we present a simple and affordable green synthesis of a nanocomposite material consisting of copper nanoparticles stabilized in a polyvinyl alcohol-glycerol matrix. TEM, UV-Vis and XRPD (X-ray Powder Diffraction) techniques were used to characterize the nanoparticles; properties of the polymer matrix were studied by NMR, IR and Raman spectroscopy as well as DSC measurements. The nanocomposite can be produced in two forms: gel and moldable plastic. Both the forms can be easily shaped at elevated temperature. The materials show very good long-term stability in air, protecting the produced copper nanoparticles from oxidation. Furthermore, we proved the application potential of the new nanocomposite as catalyst in copper catalyzed Huisgen 1,3-dipolar cycloaddition of azide and alkyne (frequently used in click-chemistry). In addition, antibacterial tests have proven inhibition of bacterial growth of both Gram-negative (Escherichia coli) and Gram-positive (Enterococcus faecalis) bacteria in the presence of the nanocomposite.
