The collaborative research team of Professor Kang Boseok from the Department of Nanoscience and Technology at Sungkyunkwan University (SKKU) and Professor Cho Gil-won from the Department of Chemical Engineering at Pohang University of Science and Technology (POSTECH) succeeded in developing a new stretchable polymer semiconductor. To create a stretchable electronic device, the semiconductor material must possess sufficient flexibility to avoid compromising its functionality. Until now, researchers have consistently proven that there are challenges in maintaining high-quality electrical performance in a stretched state. However, the newly discovered technology will help improve the performance of both elasticity and electrical performance. The collaborative research team significantly enhanced the semiconductor’s mechanical properties, including tensile strength, fracture strain, and repeated tensile stability. The team explained that “by introducing an azide photo-crosslinking agent to a polymer organics semiconductor film, a mesh-like structure forms and enhances the interaction between polymer chains,” they also emphasized, “this enables a simpler way of improving the flexibility of polymer semiconductor materials, making it valuable for future industrial purposes.”
