Abstract: A composite includes a sulfonated polyester matrix and a plurality of silver nanoparticles dispersed within the matrix. Methods to make these composites include heating a sulfonated polyester resin in an organic-free solvent adding a solution of silver (I) ion to the heated resin in water to form a mixture, adding a solution of a reducing agent to the mixture, thereby forming an emulsion of composite particles including a sulfonated polyester matrix and a plurality of silver nanoparticles disposed within the sulfonated polyester matrix. Various articles can be manufactured from such composites.
