Room temperature ionic liquids show great promise as electrolytes in various technological applications, such as energy storage or electrotunable lubrication. These applications are particularly intriguing due to the specific behavior of ionic liquids in nanoconfinement. While previous research has been focused on optimizing the required characteristics through the selection of electrolyte properties, the contribution of confining material properties in these systems has been largely overlooked. In this review, we provide constructive analysis of recent developments of theoretical and numerical studies related to the description of surface material properties impact on the ionic liquid behavior in confinement and propose potential ways for further investigations in this direction. Although the presented advances reveal the importance of surface material properties in the application processes with confined ionic liquids, there are still a lot of issues that should be thoroughly investigated in the future. We believe that this review will significantly contribute to the development of new approaches with material properties consideration for confined ionic liquid research.
