Abstract
In order to increase the viscosity of semiconductive polymers in solution, they are mixed with non-semiconductive polymers.
Claims20
A printable polymer mixture for the preparation of a double layer comprising a semiconductor layer and a non-semiconductive layer wherein the mixture exhibits semiconductive properties, the mixture comprising:
- one or more semiconductive polymers;
- and
- one or more non-semiconductive polymers,
- in a solution comprising a non-electrolytic solvent to form said printable mixture and said double layer.
1 more element
An electronic component comprising:
- a substrate;
- and on the substrate:
- a polymer mixture, the polymer mixture comprising first and second materials having respective semiconductive and non-semiconductive properties, the mixture comprising:
- one or more semiconductive polymers, and
- one or more non-semiconductive polymers,
- wherein the semiconductive and non-semiconductive polymers separate from one another after deposition on the substrate forming separate and discrete semiconductor and non-semiconductor layers on the substrate.
