Enhancing Mechanical Deformability of Rigid Conjugated Polymers through Functional Additive‐Induced Persistence Length Modulation

Advanced Functional Materials, Volume 35, Issue 43, October 22, 2025.
This study demonstrates a molecular strategy to enhance the stretchability of conjugated polymers by incorporating plasticizing molecular additives (PMAs). PMAs reduce the persistence length and promote chain entanglement, enabling deformable thin films with preserved electrical performance. A systematic analysis combining rheology, neutron scattering,
