Abstract

Multi-phase polymer films containing quantum dots (QDs) are described herein. The films have domains of primarily hydrophobic polymer and domains of primarily hydrophilic polymer. QDs, being generally more stable within a hydrophobic matrix, are dispersed primarily within the hydrophobic domains of the films. The hydrophilic domains tend to be effective at excluding oxygen.

Claims (4)

1. A method of preparing a film, the method comprising:

forming an emulsion comprising a first phase that comprises a first polymer and quantum dots and a second phase that comprises a second polymer;

depositing the emulsion between gas barrier sheets to form a film; and

curing the first and second polymers.
