METAL NANOPARTICLE-SULFONATED POLYESTER COMPOSITE AND METHOD OF MAKING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a composite comprising a sulfonated polyester matrix and a plurality of silver nanoparticles dispersed within the matrix.SOLUTION: A composite includes a sulfonated polyester matrix; and a plurality of silver nanoparticles dispersed within the matrix. A method of making the composite includes: heating a sulfonated polyester resin in a solvent containing no organic substance; adding a silver (I) ion solution to the heated resin in water to form a mixture; and adding a reducing agent solution to the mixture to perform the reduction, thereby forming an emulsion of composite particles including the sulfonated polyester matrix and the plurality of silver nanoparticles dispersed within the sulfonated polyester matrix. Various articles can be manufactured from the composite.SELECTED DRAWING: None
