Abstract
Official abstract text for this publication.
A pre-polymer formulation comprising quantum dots and a precursor for a polymer having a free volume parameter VFH2/γ with a value less than or equal to 0.03 cm3/g is disclosed. A pre-polymer formulation comprising quantum dots and a cyclohexylacrylate monomer is further disclosed. Also disclosed are a quantum dot composition including quantum dots dispersed in a polymer matrix, the quantum dot composition being prepared from a pre-polymer formulation comprising quantum dots and a precursor for a polymer having a free volume parameter VFH2/γ with a value less than or equal to cm3/g; a method; and other products including a quantum dot composition described herein.
First claim
Opening claim text (preview).
What is claimed is: 1. A quantum dot composition including quantum dots dispersed in a cyclohexylacrylate-based polymer matrix. 2. The quantum dot composition in accordance with claim 1 , wherein an adhesion promoter is cross-linked to the polymer matrix. 3. The quantum dot composition in accordance with claim 2 , wherein the adhesion promoter comprises a UV light curable optically transparent acrylic based material having adhesive properties. 4. The quantum dot composition in accordance with claim 2 , wherein the adhesion promoter includes a UV light curable acrylic-based optically clear adhesive. 5. The quantum dot composition in accordance with claim 2 , wherein the adhesion promoter comprises bis[2-(methyloyloxy)ethyl]phosphate. 6. The quantum dot composition in accordance with claim 2 , wherein the adhesion promoter comprises a methacrylate monomer base structure including a phosphate functionality. 7. The quantum dot composition in accordance with claim 2 , wherein the adhesion promoter comprises an acrylate monomer base structure including a carboxylate functionality. 8. The quantum dot composition in accordance with claim 2 , wherein the adhesion promoter comprises N-methyl-aza-2,2,4-trimethylsilacyclopentane. 9. The quantum dot composition in accordance with claim 2 , wherein the composition includes the adhesion promoter in an amount greater than 0 up to about 10 weight percent of the composition. 10. The quantum dot composition in accordance with claim 1 , wherein composition includes quantum dots in an amount greater than 0 up to about 25 weight percent of the composition. 11. The quantum dot composition in accordance with claim 1 , further including an emission stabilizer. 12. The quantum dot composition in accordance with claim 11 , wherein the emission stabilizer comprises at least one of potassium dodecyl phosphate and trioctyl phosphine oxide. 13. The quantum dot composition in accordance with claim 11 , wherein the composition includes the emission stabilizer in an amount greater than 0 up to about 10 weight percent of the composition. 14. The quantum dot composition in accordance with claim 1 further comprising scatterers. 15. The quantum dot composition in accordance with claim 14 , wherein the composition includes the scatterers in an amount greater than 0 up to about 15 weight percent of the composition. 16. The quantum dot composition in accordance with claim 1 further comprising a thixotrope. 17. The quantum dot composition in accordance with claim 16 , wherein the composition includes the thixotrope in an amount greater than 0 up to about 15 weight percent of the composition.
