In recent years a subclass of polyelectrolytes named poly(ionic liquid)s (PILs) have attracted intensive interest in the field of polymer and materials science due to some of their unusual physical properties, compared to traditional polyelectrolytes. They are characterized as multifunctional polyelectrolytes in a wide application spectrum, such as solid ion conductor, separation, sorption, catalysis, membrane, and many more. PIL colloidal particles, including nanoparticles, nanogels, micelles, and core–shell nanocomposite particles, are an important part of the PIL research. Herein, the chemical structure, preparation method and application examples of the colloidal PIL systems are summarized along with an intensive discussion of their advantages and limitations in some specific cases. Micelles formed from PIL homopolymer and copolymer in selective conditions are given a detailed description. At the end, the employment of PIL polymers to stabilize carbon materials to form a colloid dispersion of carbon nanostructures has been particularly emphasized.
