Claims17
A method of preparing a quantum dot-resin nanocomposite, the method comprising:
- selecting an organic material to be disposed on a surface of a plurality of quantum dots, a resin, and a solvent;
- contacting the organic material with the surface of the quantum dots to provide functionalized quantum dots;
- combining the functionalized quantum dots, the resin, and the solvent;
- and
- emulsifying the same to prepare the quantum dot-resin nanocomposite,
- wherein the resin has a solubility parameter greater than a solubility parameter of both the organic material and the solvent, and the organic material has a solubility parameter greater than a solubility parameter of the solvent,
- wherein each of the solvent, the resin, and the organic material has a solubility parameter of about 10 MPa1/2 to about 30 MPa1/2, respectively,
- wherein the organic material is derived from a compound of the formula RCOOH, RNH2, R2NH, R3N, RSH, R3PO, R3P, ROH, RCOOR′, or a combination thereof, wherein R and R′ are each independently a C1-C24 alkyl group or a C5-C24 aryl group, and
- wherein the resin comprises a thiolene resin.
