ABSTRACT:
The present disclosure provides a method of preparing a nanocomposite: (a) providing a first solution having a first organic solvent comprising a non-alkali metal salt, a carboxylic acid comprising at least one aryl group, and a polymer dissolved therein; (b) providing a sulfide material; (c) combining the first solution and the sulfide material; and (d) isolating the nanocomposite, wherein the nanocomposite comprises the polymer and a plurality of nanoparticles, wherein each nanoparticle comprises at least one metal sulfide nanocrystal having a surface modified with the carboxylic acid comprising at least one aryl group. The present disclosure also provides the nanocomposites and articles prepared therefrom.
