Advancing the dynamic mechanical analysis of organic semiconductor materials

Abstract

Dynamic mechanical analysis (DMA) is a powerful technique for characterizing the mechanical properties of a wide range of materials. However, the importance of DMA in studying organic semiconductors has not been fully appreciated. In this Highlight, we discuss recent advancements in the use of DMA in understanding the viscoelastic and mechanical properties and thermal transitions of organic semiconductor materials. In particular, the information gained from DMA can serve as new guides for the device optimisation of organic solar cells. Furthermore, we present key findings, challenges, and future directions to advance the application of DMA in organic electronics.
