Conjugated polymers have gained significant interest as highly conducting organic materials with versatile surface morphology. In this study, we demonstrate that the electrodeposition of poly(3,4-ethylenedioxythiophene), PEDOT, in the presence of a D-glucopyranoside-derived ionic liquid (IL) results in the formation of highly corrugated three-dimensional structures. The as-formed PEDOT/IL is found to outperform PEDOT electrodeposited in the presence of a conventional electrolyte (KCl) in terms of the low impedance at the biologically relevant frequency (1 kHz) and low charge transfer resistance. Consequently, it can be inferred that the unique surface morphology and beneficial electrochemical performance will facilitate the application of PEDOT/IL in biomedical engineering, especially in the field of neural interfaces and tissue scaffolds.

共轭聚合物作为具有多种表面形态的高导电有机材料已引起人们的极大兴趣。在这项研究中，我们证明了在存在D-吡喃葡萄糖苷衍生的离子液体（IL）的情况下，聚（3,4-乙撑二氧噻吩）PEDOT的电沉积会导致形成高度波纹的三维结构。就生物学相关频率（1kHz）下的低阻抗和低电荷转移电阻而言，发现形成的PEDOT / IL优于在常规电解质（KCl）存在下电沉积的PEDOT。因此，可以推断出独特的表面形态和有益的电化学性能将促进PEDOT / IL在生物医学工程中的应用，特别是在神经界面和组织支架领域。
