Summary: In this study, a highly conductive, ultrastrong, and flexible PEDOT:PSS/EMIM:DCA fiber was prepared by wet-spinning and subsequent sulfuric acid-immersion-drawing process. The fiber exhibited excellent properties such as high tensile strength and low Young's modulus, which were attributed to the removal of PSS and high crystallinity and orientation of PEDOT. Various flexible and wearable electronic devices were constructed based on the P/ED fiber.

Summary: This study investigated metal-ion crosslinked polyoxadiazole (POD) as silicon anode binders, and found that the ionic radius and valence state significantly influence the polymer's mechanical properties and the electrolyte's infiltration. Calcium (Ca)-crosslinked POD showed excellent mechanical strength and improved cycling stability of the silicon anode. The cell with Ca-POD binder retained a capacity of 1770.1 mA h g(-1) after 100 cycles at 0.2 C, which is 285% higher than that of the cell with the PAALi binder (620.6 mA h g(-1)). This novel strategy using metal-ion crosslinking polymer binders provides a new pathway for high-performance binders in next-generation rechargeable batteries.

Summary: Wet-spinning technology plays a crucial role in wearable electronics development. PEDOT: PSS fibers, known for their environmental friendliness and low cost, have been widely studied in this field. However, the conductivity of PEDOT: PSS fibers spun by conventional coagulation bath is low. In this study, a novel coagulation bath made of ionic liquid, ethanol, and water was proposed, resulting in PEDOT: PSS fibers with high conductivity, promising for wearable electronic applications.

Summary: A unique coagulation bath system without organic solvents has been developed for wet-spinning PEDOT: PSS conductive fibers, promoting green and sustainable development. The addition of metal ions in water leads to fiber solidification, and the resulting fibers exhibit a record-breaking tensile breaking strength of 1263.1 +/- 58.3 MPa with the aid of Fe3+ and thermal drawing. Knitted fabrics made from these robust fibers show exceptional flexibility and thermal insulation, indicating their great potential in flexible electronic fabrics.
