An article of manufacture includes a zinc sulfide layer and a coupling agent adhered to the zinc sulfide layer by a disulfide bond. The coupling agent comprises a functional group extending from the zinc sulfide layer. 1. A method of making an optical element , the method comprising:reacting a coupling agent with a zinc sulfide surface, at a basic pH, to form a covalent disulfide bond between the coupling agent and the zinc sulfide surface; andreacting an organic polymer with the coupling agent.2. The method of claim 1 , further comprising treating an isothiouronium salt with a basic compound to form the coupling agent.3. The method of claim 2 , further comprising reacting thiourea with a compound having the following formula: X(CH)Y to form the isothiouronium salt;wherein X is an acrylate group, an acyl halide group, an amide group, an amine group, a carboxylate group, a carboxylate thiol group, an epoxy group, an ester group, an ether group, a halogen, a hydroxamic acid group, a hydroxyl group, a nitrate group, a nitrile group, a phosphate group, a phosphine group, a phosphonic acid group, a silane group, a sulfate group, a sulfide group, a sulfite group, a thiolate group, an alkyl group, an alkenyl group, an alkynyl group, an aryl group, an azide group, an acetal group, an aldehyde group, a diene group, a cycloalkyl group, a cycloaryl group, a polycycloaryl group, a substituted cycloaryl group, or any combination thereof; andY is a hydroxide group, an amino group, an alkoxide group, a fluoride, a chloride, a bromide, an iodide, a methyl sulfate group, a mesylate group, a triflate group, a tosylate group, a dialkylether group, a nitrate group, a phosphate group, an ammonium group, an inorganic ester group, a carboxylate group, a phenoxide group, or an amide group.4. The method of claim 1 , wherein the coupling agent has a functional group that forms a contact product with the organic polymer.5. The method of claim 4 , wherein the functional group is an acrylate ...
