在这里，介绍了一种具有电子和粘合性能的聚合物共混物活性层。将各种共轭聚合物与显示出高粘附性的基于邻苯二酚的聚合物共混，使得共混物用作多功能粘性有机薄膜晶体管（OTFT）的有源层。无论组成如何，共混膜在OTFT中保持相对恒定的场效应电荷载流子迁移率。搭接剪切粘合强度测试表明，所有共混物膜具有粘合性能，粘合值范围为0.05至4.30 MPa。凭借相对一致的迁移率和不同成分下的粘合性能，共轭聚合物和粘合聚合物的混合物可以导致下一代有机晶体管，用于稳定的3D堆叠和防水粘合传感器。
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.
