Most of the microstructures of solid materials, such as ceramics, metals, polymers and composites in their dry conditions, are characterized by electron microscopy. However, the observation methods for hydrous materials have still been under development because the wet condition is not suitable for the electron microscopy under high vacuum conditions. This difficulty in the characterization of the hydrous materials is a barrier to the research progress related to wet materials processing. In this review paper, developed observation methods with the aid of a hydrophilic ionic liquid (IL) for various kinds of hydrated materials are reported. By the developed observation methods, the characterization of hydrous materials, such as seaweed, agar gel and a HAp green body, is enabled and extended to a range of related fields. Based on the interaction between water molecules and hydrophilic IL, the mechanism for the observation of wet materials using the hydrophilic IL has been clarified and the molecular dynamics of the IL and solvents have been studied. In addition, an IL-inorganic composite material was successfully fabricated by mixing of IL and montmorillonite clay in the proper ratio, which suggests possibility to invent novel electron conductive transparent thin films., application/pdf}, pages = {45--52}, title = {Application of Ionic Liquids on Microscopic Observation of Hydrated Materials}, volume = {1}, year = {2013}, yomi = {シライ, タカシ and フジ, マサヨシ} }
