Aerosol-jettable silver nanoparticle-based convertible ink

Abstract

A method of forming a convertible ink. The method includes: performing a polyol process with a metal salt, a capping agent and a solvent to produce encapsulated nanospheres in a first aqueous solution; reducing the amount of capping agent in the solution. The capping agent can be reduced by: adding solvent soluble with the capping agent and agitating the mixture via centrifugation to form a supernatant and a precipitate that includes the encapsulated nanospheres; removing the supernatant; adding a second solvent to the precipitate to form a second solution; agitating the second solution to form a second supernatant and a precipitate that includes the encapsulated nanospheres; and removing the second supernatant.
