摘　　要：The conductive polymer poly-3,4-ethylenedioxythiophene(PEDOT),recognized for its superior electrical conductivity and biocompatibility,has become an attractive material for developing wearable technologies and bioelectronics.Nevertheless,the complexities associated with PEDOT's patterning synthesis on diverse substrates persist despite recent technological progress.In this study,we introduce a novel deep eutectic solvent(DES)-induced vapor phase polymerization technique,facilitating nonrestrictive patterning polymerization of PEDOT across diverse substrates.By controlling the quantity of DES adsorbed per unit area on the substrates,PEDOT can be effectively patternized on cellulose,wood,plastic,glass,and even hydrogels.The resultant patterned PEDOT exhibits numerous benefits,such as an impressive electronic conductivity of 282 S·m-1,a high specific surface area of 5.29 m^(2)·g-1,and an extensive electrochemical stability range from-1.4 to 2.4 V in a phosphate-buffered saline.To underscore the practicality and diverse applications of this DES-induced approach,we present multiple examples emphasizing its integration into self-supporting flexible electrodes,neuroelectrode interfaces,and precision circuit repair methodologies.
