Green Synthesis of Silver Nanoparticles and Their Application in Thin Polymer Films

The focus of the present study is on synthesis procedures, morphology and application of silver nanoparticles (AgNPs). A green synthesis approach was performed with aqueous extracts from lawn grass and parsley (Petroselinum crispum Mill.), both of them microwave assisted. The formation of the silver nanoparticles was observed using UV-Vis spectroscopy (Boeco S26 spectrophotometer); they were characterized by transmission electron microscopy (TEM). The absorption spectra show peaks in the range 380–400 nm for all products. The TEM images depicted that the synthesis method yield nanoparticles with spherical shape and different size. This gives rise for a wide range of application of AgNPs which may be used as additives in papers and polymers due to their antimicrobial properties which depend on particle size and shape.
