Polymeric conductor donor and transfer method
View Patent ↗The present invention relates to a donor laminate for transfer of a conductive layer comprising at least one electronically conductive polymer on to a receiver, wherein the receiver is a component of a device. The present invention also relates to methods pertinent to such transfers.
1. A method of transferring comprising providing a laminate for transfer of a conductive layer comprising a substrate having thereon a conductive layer comprising at least one transparent, electronically conductive polymer and a polyanion, in contact with said substrate, bringing the side of said laminate bearing said conductive layer into contact with a receiver element to transfer said conductive layer to said receiver element,
wherein the conductive layer has a peel force of less than 100 grams per inch for separation from the substrate at room temperature.
2. The method of claim 1 wherein heat is applied during transfer.
3. The method of claim 1 wherein pressure is applied during transfer.
4. The method of claim 1 wherein heat and pressure are applied during transfer.
5. The method of claim 2 wherein a light source is utilized to supply heat during transfer.
6. The method of claim 2 wherein a resistive head is used to supply heat during transfer.
7. The method of claim 1 wherein the receiver element comprises glass.
8. The method of claim 1 wherein said receiver element comprises a flexible polymeric material.
9. The method of claim 1 wherein the transfer is in a pattern for an electrode.
10. The method of claim 1 wherein said transfer is in a pattern.
11. The method of claim 1 wherein said receiver element is solvent sensitive.
12. The method of claim 1 wherein said receiver element comprises an organic light emitting diode material.
13. The method of claim 3 wherein said pressure is applied by a patterned roller.
14. The method of claim 3 wherein said pressure is applied by acoustic or mechanical force.
15. The method of claim 1 wherein the surface of said substrate in contact with said conductive layer comprises a release material.
16. The method of claim 1 wherein transferring utilizes an adhesive between said conductive layer and said receiver element.
17. The product formed by the method of claim 1 .
18. The method of claim 5 wherein the light source is utilized to supply heat during transfer is a laser.
19. The method of claim 1 , wherein said conductive layer has an FOM less than or equal to 100 wherein FOM is defined as the slope of the plot of ln (1/T) versus [1/SER]: and
wherein
T=visual light transmission
SER=surface electrical resistance in ohm per square
FOM=figure of merit, and
wherein the SER has a value of less than or equal to 1000 ohm per square.
