Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 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.
