The properties of various mixtures of a zwitterionic ionic liquid (ZIs-1) and LiNTf2, including their conductivity, have been studied showing how they can be adjusted through their molar composition. Conductivity tends to increase with the LiNTf2 content although it presents a minimum at the region close to the eutectic point. These mixtures also provide excellent features as liquid phases for the preparation of composite materials based on crosslinked PILs. The prepared films display excellent and tuneable properties as conducting materials, with conductivities that can be higher than 10-2 S cm-1 above 100 °C. The selected polymeric compositions show very good mechanical properties and thermal stability, even for low crosslinking degrees, along with a suitable flexibility and good transparency. The final properties of the films correlate with the composition of the monomeric mixture used and with that of the ZIs-1:LiNTf2 mixture.
对两性离子液体（ZIs-1）和LiNTf2的各种混合物的性质，包括其电导率进行了研究，展示了如何通过它们的摩尔组成来调节这些性质。尽管在接近共晶点的区域电导率呈现最小值，但电导率往往会随着LiNTf2含量的增加而升高。这些混合物作为基于交联聚离子液体（PILs）的复合材料制备的液相也具有优异的特性。制备的薄膜作为导电材料表现出优异且可调节的性能，在100℃以上电导率可高于10⁻² S cm⁻¹。所选的聚合物组合物即使对于低交联度也表现出非常好的机械性能和热稳定性，同时具有合适的柔韧性和良好的透明度。薄膜的最终性能与所用单体混合物的组成以及ZIs-1:LiNTf2混合物的组成相关。
