Abstract
A method includes 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, reducing silver (I) to silver (0) by heating the mixture from about 65° C. to about 90° C., thereby forming an emulsion of composite particles comprising a sulfonated polyester matrix and a plurality of silver nanoparticles disposed within the sulfonated polyester matrix, and allowing the silver nanoparticles to agglomerate into a silver nanodendrite structure.

A method comprising:
- 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;
- reducing silver (I) to silver(0) by heating the mixture from about 65° C. to about 90° C., thereby forming an emulsion of composite particles comprising a sulfonated polyester matrix and a plurality of silver nanoparticles disposed within the sulfonated polyester matrix;
- and
- allowing the silver nanoparticles to agglomerate into a silver nanodendrite structure.

A method comprising:
- heating a branched sulfonated polyester resin in de-ionized water;
- adding a solution of silver (I) ion to the heated resin in water to form a mixture, wherein silver (I) ion is present in a non-zero amount up to about 1 percent by weight of the mixture;
- reducing silver (I) to silver(0) by heating the mixture from about 65° C. to about 90° C., thereby forming an emulsion of composite particles comprising a sulfonated polyester matrix and a plurality of silver nanoparticles disposed within the sulfonated polyester matrix;
- and
- allowing the silver nanoparticles to agglomerate into a silver nanodendrite structure by leaving the emulsion to sit at ambient temperature for at least one week.
