Professor Byung Hoon Lee's collaborative research team at IMMS, together with researchers from Ajou University and ETH Zurich, has developed a next-generation stretchable semiconductor material that simultaneously achieves high charge mobility and exceptional mechanical stretchability.
The team established a multiblock copolymer platform by precisely connecting conductive conjugated polymer blocks with elastic polymer blocks at the molecular level. This strategy overcame the long-standing trade-off between charge mobility and stretchability, demonstrating stable electrical performance while maintaining high charge mobility under strains exceeding 300%.
The newly developed material maintained stable electrical properties under repeated mechanical deformation and after high-temperature thermal treatment, highlighting its potential for wearable electronics, electronic skin, and soft robotics. The research was published in the internationally renowned journal <Angewandte Chemie International Edition> and supported by the National Research Laboratory (NRL 2.0) program and other research funding initiatives.
IMMS will continue advancing world-class research in next-generation semiconductor materials and flexible electronic devices while developing innovative technologies for future electronic materials.
