Stretchable Polymer Semiconductors
Abstract
Flexible organic electronics (e.g. solar cells, light-emitting diodes and field-effect transistors) have attracted considerable attention over the past decade. Despite recent progress in developing new organic semiconductors, stretchable semiconducting or conducting elastomers have yet been explored in detail. Realization of these materials will result in increased robustness and potentially new applications in wearable electronics, since these materials can be fully solution processed and provide improved form factor (e.g. arbitrary 3D shapes) for organic devices. Therefore, the goal for this project is to develop materials chemistry and formulate an understanding to enable intrinsically stretchable electronic devices. In this work, we systematically investigated a number of molecular design approaches for realizing both good charge transport as well as good mechanical properties. Specifically, we investigated the effects of H-bonding strength, effect of additives, effects of polymer semiconductor degree of crystallinity, effects of crosslinker design. Our work advanced our understanding of stretchable polymer semiconductor design and provided guiding principles for future polymer semiconductor development for stretchable and flexible electronics.
