Background:

Poly-3,4-ethylenedioxythiophene (PEDOT) is a conductive polymer with excellent electrical conductivity and biocompatibility, making it ideal for wearable technologies and bioelectronics.
Current methods for patterning PEDOT on diverse substrates are complex and limited, hindering its widespread application.

Purpose of the Study:

To develop a novel, nonrestrictive patterning synthesis technique for PEDOT.
To enable PEDOT patterning on a wide range of substrates including cellulose, wood, plastic, glass, and hydrogels.

Main Methods:

A deep eutectic solvent (DES)-induced vapor phase polymerization technique was employed.
Control over DES adsorption per unit area on substrates allowed for precise PEDOT patterning.

Main Results:

Achieved high electronic conductivity of 282 S·m⁻¹ for patterned PEDOT.
Exhibited a high specific surface area of 5.29 m²·g⁻¹.
Demonstrated extensive electrochemical stability from -1.4 to 2.4 V in phosphate-buffered saline.

Conclusions:

The DES-induced vapor phase polymerization is a versatile and effective method for patterning PEDOT on diverse materials.
This technique facilitates the integration of patterned PEDOT into flexible electrodes, neuroelectrode interfaces, and precision circuit repair.
