Summary: | Here, a polymer blend active layer that exhibits both electronic and adhesive properties is introduced. Various conjugated polymers are blended with a catechol‐based polymer that shows high adhesion, such that blends serve as the active layer of multifunctional sticky organic thin‐film transistors (OTFTs). Blend films maintain relatively constant field‐effect charge carrier mobility in OTFTs regardless of composition. Lap shear adhesion strength tests show that all blend films exhibit adhesive properties with adhesion values ranging from 0.05 to 4.30 MPa. With relatively consistent mobility and the presence of adhesive properties at different compositions, blends of conjugated and adhesive polymers can lead to next‐generation organic transistors for stable 3D stacking and waterproof adhesive sensors.
The addition of an adhesive polymer to the active layer of organic thin‐film transistors creates multifunctional devices that possess both semiconductive and adhesive properties. Reasonable mobilities are observed when either one of the three conjugated polymers is blended with an adhesive polymer. All blend films exhibit adhesive properties with adhesion values ranging from 0.05 to 4.30 MPa. |
