چكيده فارسي :
Copolymer latex nanoparticles were synthesized by emulsifier-free emulsiom polymerization, and used for the preparation of the fluorescent polymer nanoparticles by doping fluorescein. The prepared system is usable for anticounterfeiting inks and security markings of barcodes, logos and banknotes. Poly(methyl methacrylate) latex nanoparticlescontaining 10 wt% of 2-(dimethylamino)ethyl methacrylate showed the highest ultraviolet-visible absorbance and also fluorescence emission intensity because of its polar gropus. Therefore, this sample was chosen for the preparation of anticounterfeiting inksand fibers.
