Abstract
Silver nanoshells on styrene–acrylic acid copolymer latex spheres (PSA) weredeposited by an in situ chemical reduction method, ageing a colloid solution at85 °C containingPSA latex, AgNO3, urotropine, and poly-(vinylpyrrolidone). SEM and TEM observations showed that thesilver nanoshells were made of closely packed silver nanoparticles of different sizes andmorphologies. UV–visible absorption spectra were recorded to investigate their opticalproperties.
