Abstract

We successfully prepared high-quality vacuum-deposited thin films of ionic liquid crystal 1-hexadecyl-3-methylimidazolium hexafluorophosphate ([C16mim][PF6]). The key point is to anneal the films in vacuum at the liquid crystal temperature of [C16mim][PF6], thereby much improving their crystallinity, surface smoothness, and air-exposure stability. The differential capacitance measurement of such a high-quality thin film revealed that an electric double layer was formed in the liquid crystalline phase, while it behaves like a normal dielectric in the crystal phase.
