One-dimensional iontronics have the unique advantages of small size and strong integration ability,but their low ion mobility at ambient temperature limits their application in the field of bio-integrated electronics.In this paper,polycationic electrolytes poly(VIM-m-TFSI)with low glass transition temperature(Tg)are synthesized by introducing alkoxy group into traditional ionic liquid based on imidazolium through side-chain engineering and copolymerized with poly(ethylene glycol)methacrylate(PEGMA).They achieve higher chain mobility at room temperature,leading a lower ionic impedance and wider electrochemical window(-2.7-+2.7 V).By simply bonding with polyanionic electrolyte poly(AMPS-EMIM),a high-performance flexible semiconductor ionic-junction is constructed to achieved a solid ionic diode with a rectification ratio of 127.The two polyelectrolyte solutions show excellent solution processability and rheological properties,which could be used as 3D printing inks directly.The integrated molding construction of ionic-junction semiconductor fibers are realized by three-dimension(3D)printing technology,and a large-area textile based on 5×5 array units is obtained to initially realize"0-1"rectification of input signal.It verifies the application potential of next-generation ionic-junction semiconductor fibers in the field of fabric logic circuits.
