Abstract
A simple, highly versatile method for fixing smooth materials that utilizes a water pasting method can be provided by interposing an ionic liquid between smooth materials such as glass or resin not impregnated with an ionic liquid and fixing these smooth materials.
Claims5
A method for fixing materials having such smooth surfaces that the smooth surfaces can be fixed to each other by a water bonding method, comprising interposing an ionic liquid between the materials that are not impregnated with the ionic liquid, and immobilizing the materials in an easily peelable state by the water bonding method,
- wherein said ionic liquid is selected from the group consisting of a quaternary ammonium salt type ionic liquid represented by the general formula (1), imidazolium salt type ionic liquid, pyridinium salt type ionic liquid, quaternary phosphonium salt type ionic liquid, choline type ionic liquid, and sulfonium salt type ionic liquid,
- wherein R1 to R4 each independently represent an alkyl group having 1 to 4 carbon atoms or an alkoxyalkyl group represented by —(CH2)n—OR, n represents an integer of 1 or 2, R represents an alkyl group having 1 to 4 carbon atoms, any one of R1 to R4 represents an alkoxyalkyl group, and X− represents a monovalent anion.
A method for producing a laminate, comprising immobilizing a base material that is not impregnated with the ionic liquid on a substrate that is not impregnated with the ionic liquid in an easily peelable state by a water bonding method using an ionic liquid and then applying a laminate material to a surface of the base material by spin coating method,
- wherein said ionic liquid is selected from the group consisting of a quaternary ammonium salt type ionic liquid represented by the general formula (1), imidazolium salt type ionic liquid, pyridinium salt type ionic liquid, quaternary phosphonium salt type ionic liquid, choline type ionic liquid, and sulfonium salt type ionic liquid,
- wherein R1 to R4 each independently represent an alkyl group having 1 to 4 carbon atoms or an alkoxyalkyl group represented by —(CH2)n—OR, n represents an integer of 1 or 2, R represents an alkyl group having 1 to 4 carbon atoms, any one of R1 to R4 represents an alkoxyalkyl group, and X− represents a monovalent anion.
