摘要

一系列基于三正烷基铵阳离子和甲磺酸盐/三氟乙酸盐阴离子的原生离子液体 (PIL) 被加入聚合物基质中，形成离子凝胶 (IG)。研究人员通过 PFG-NMR 对这些系统的热和电化学行为以及离子运动进行了研究。在高温条件下，ILs/IGs 的离子导电率在 10-4 - 10-3 Scm-1 之间，扩散系数约为 10-11 m2s-1。通过立体光刻方法，可以成功地三维打印出含有 70 wt% IL 的 IG，从而为结构化离子导电膜等应用开辟了道路。

3D Printable Polymer Electrolytes for Ionic Conduction based on Protic Ionic Liquids.

A range of protic ionic liquids (PILs) based on tri-n-alkylammonium cations and mesylate/triflate anions were incorporated into a polymer matrix to form ionogels (IGs). These systems were investigated for their thermal and electrochemical behaviour, as well as under the aspect of ion motion via PFG-NMR. The ionic conductivities of the ILs/IGs are in the range of 10‑4 - 10-3 Scm-1 at elevated temperatures and the diffusion coefficients were around 10‑11 m2s-1. Successful 3D printing of an IG with 70 wt% of IL is possible via stereolithography approaches, opening up applications in, e.g., structured ion-conductive membranes.
