초록 Organic or plastic bioelectronics has recently emerged as a key driver for the soft molecular and polymeric electronic materials. These materials’ versatile processability, intrinsic biocompatibility, functional tunability, and mechanical flexibilities are among the major factors that make organic-based systems particularly promising for wearable and implantable platforms. However, our understanding has been limited on the fundamental process-structure-property relationships of relevant bioelectronic materials. In this presentation, we report on a solution-based post-deposition crystallization technique applicable to a conventional conducting polymer, and comprehensively elucidate its dramatically beneficial effects on the electrochemical devices, which are widely adopted as a sensor and transducer in emerging bioelectronic systems. In addition to the intended effect, the induced nanoscale structural re-arrangements give rise to the compositional change that leads to the improved anti-swelling property, volumetric capacitance, and thermal/environmental stability. It is expected that both the fundamental understanding and application potentials underlined in this study will serve as an important guideline for the development of viable bioelectronics technologies.
