Self‐healing electronic materials are of primary interest for bioelectronics and sustainable electronics. In this work, autonomic self‐healing of films obtained from mixtures of the conducting polymer poly(3,4‐ethylenedioxythiophene) doped with polystyrene sulfonate (PEDOT:PSS) and polyethylene glycol (PEG) is reported. The presence of PEG in PEDOT:PSS films decreases the elastic modulus and increases the elongation at break, thus leading to a softer material with enhanced self‐healing characteristics. In situ imaging of the cutting/healing process shows that the healing mechanism is likely due to flowing back of the material to the damaged area right after the cutting.

通过添加聚乙二醇实现PEDOT：PSS的自主自我修复

自修复电子材料是生物电子学和可持续电子学的主要兴趣。在这项工作中，报道了从掺杂有聚苯乙烯磺酸盐（PEDOT：PSS）和聚乙二醇（PEG）的导电聚合物聚（3,4-乙二氧基噻吩）的混合物中获得的膜的自修复。PEDOT：PSS膜中PEG的存在会降低弹性模量并增加断裂伸长率，从而导致具有更强自我修复特性的较软材料。切割/修复过程的原位成像显示，修复机制很可能是由于材料在切割后立即流回到受损区域。
