Query: Percolation Phase Transition from Ionic Liquids to Ionic Liquid Crystals   As typical complex liquids, ionic liquids (ILs) exhibit phases beyond the
description of simple liquid theories. In particular, with an intermediate
cationic side-chain length, ILs can form the nanoscale segregated liquid (NSL)
phase, which will eventually transform into the ionic liquid crystal (ILC)
phase when the side chains are adequately long. However, the microscopic
mechanism of this transformation is still unclear. In this work, by means of
coarse-grained molecular dynamics simulation, we show that, with increasing
cationic side-chain length, some local pieces of non-polar domains are
gradually formed by side chains aligned in parallel inside the NSL phase,
before an abrupt percolation phase transition happens when the system
transforms into the ILC phase, manifesting that it is a critical phenomenon.
Percolation phase transition is applied to ILs, providing new insights into
many recent observations both in experiments and simulations.
