Problems solved by technology

However, under relatively high pressure conditions, the ionic liquid usually leaks from the porous structure support used to immobilize the ionic liquid, and it is difficult to use it under high pressure. For example, gels with high strength (such as toughness) are desired. shaped structure
[0008]In this way, for the interpenetrating meshes containing ionic liquids that are easy to prepare and have long-term storage properties, transparency, softness, self-supporting properties, moldability and toughness There is room for improvement in terms of structures and their manufacturing methods

Embodiment 1

[0145] The following components were mixed and stirred at room temperature for 1 hour: AEROSIL (registered trademark) 130 (manufactured by Japan Aerosil Co., Ltd., specific surface area: 130 m 2 / g) 0.15g; N, N-dimethylacrylamide (DMAAm) 0.43g as a monomer for forming a polymer network structure; 1-ethyl-3-methylimidazolium bis (Fluorosulfonyl)imide salt ([Emim][FSI]) 2.4g; N,N'-methylenebisacrylamide (MBAA) as a crosslinking agent 0.0135g (2 mol% relative to DMAAm ); 0.0061 g (0.5 mol % with respect to DMAAm) of Irgacure 907 (manufactured by BASF Corporation) as a polymerization initiator; 0.24 g of ethanol as a dispersion medium of silica particles. Using an applicator, cast on a 50 μm thick polypropylene film with an arbitrary thickness, cover the coating film with a PET film that has been released from the mold so that air does not enter, and irradiate with 365 nm ultraviolet rays (illuminance 20 mW / cm2) 2 ) for 10 minutes to polymerize the monomers used to form the polym...

Embodiment 2

[0147] Except that 1-ethyl-3-methylimidazolium dicyanamide salt ([Emim][DCA]) was used instead of 1-ethyl-3-methylimidazolium bis(fluorosulfonyl)imide salt ([Emim] [FSI]) was used as the ionic liquid, and the ionic liquid-containing structure of Example 2 was produced in the same manner as in Example 1.

Embodiment 3

[0149] In addition to using a specific surface area of ​​50m 2 / g of silica particles (AEROSIL (registered trademark) OX-50 manufactured by Japan Aerosil Co., Ltd.) instead of AEROSIL (registered trademark) 130 as the inorganic particles, the same operation as in Example 1 was carried out to prepare Example 3 containing Structures of ionic liquids.

Abstract

One objective of the present invention is to provide a method by which an ionic liquid-containing network structure is able to be produced with high productivity. A method for producing an ionic liquid-containing structure, which comprises: an inorganic particle network structure formation step for forming a network structure, which is composed of inorganic particles, in the presence of an ionic liquid; and a polymer network structure formation step for forming a network structure by means of polymerization of a monomer component that contains at least a polar group-containing monomer in the presence of the ionic liquid.

Description

technical field [0001] The present invention relates to a method for producing a structure containing an ionic liquid, and a structure containing an ionic liquid. Background technique [0002] In recent years, a technique of applying an interpenetrating network structure to a gel that responds to two or more stimuli among redox, temperature, electricity, etc. has been proposed (Patent Document 1). [0003] Examples of the high-strength gel structure (IPN gel, double network (DN) gel) having such an interpenetrating network structure include hydrogels using water as a solvent. As high-strength hydrogels with other structures, slide-ring (slide-ring) gels, four-arm polyethylene glycol (tetra-PEG) gels, nanocomposite gels, etc. have been proposed, but all use volatile water Since it is a solvent, it volatilizes in an atmospheric environment, and there is a problem that it cannot be stored for a long time. [0004] On the other hand, as a gel structure that can be stored for a...
