Upon photolysis of photoinitator, the generated radicals not only reduce Cu(II) into Cu(I) activator to catalyst the CuAAC click reaction, but also simultaneously generate AgNPs from AgNO3 through electron transfer reaction. Due to their reduction potentials difference, the polymer matrix is formed before the formation of AgNPs, assisting to eliminate the agglomeration of them. The thermoset structures are confirmed by FT-IR and solubility tests, whereas the presence of AgNPs is proven by transmission electron microscopy with energy dispersive X-ray system analyzer. The samples containing 5 and 10% AgNPs exhibited strong inhibition zones, where all kinds of bacteria (gram-positive (Staphylococcus Aureus) and gram-negative (Escherichia Coli)) were killed in the surrounding of the film samples.EnglishCopper-catalyzed azide-alkyne cycloaddition click chemistryBacteriaElectron transitionsElectronsEscherichia coliFree radical reactionsHigh resolution transmission electron microscopyMetal nanoparticlesNanocompositesNanoparticlesPhotolysisPhotopolymerizationThermosetsTransmission electron microscopyAntibacterial propertiesAzide-alkyne cycloadditionElectron-transfer reactionsEnergy dispersive x-rayPhoto-induced electron transferSilver nanoparticlesSilver nanoparticles (AgNps)Staphylococcus aureusSilverArticle10.1016/j.porgcoat.2017.01.011
