Abstract: This ionic liquid-containing laminate includes a porous layer having affinity with ionic liquids (C), said layer holding an ionic liquid-containing liquid (A) within voids therein, and a porous layer lacking affinity with ionic liquids (B). The porous layer having affinity with ionic liquids (C) may include an inorganic material (e.g., metal oxide particles having an average particle size of 0.001 to 10 μm on a number basis). The ionic liquid-containing liquid (A) may include an ionic liquid containing cations selected from ammonium, imidazolium and phosphonium cations, and anions selected from fluorine-containing anions, cyano-containing anions and amino acid-derived anions. The porous layer having affinity with ionic liquids (C) may include 1 to 100 volume parts of the ionic liquid-containing liquid (A) with respect to 100 volume parts of voids therein. The ionic liquid-containing laminate is easily formable, and is able to stably hold (or fix) the ionic liquid while maintaining said liquid in a liquid state.

Abstract: Used as a heat transport medium to be transported with a fluid that is liquid in an operating temperature range is a medium in which a latent heat storage material is penetrated in a porous material, wherein the latent heat storage material is incompatible with the fluid and has a melting point within the operating temperature range, and the porous material has a liquid repellency to the fluid, an affinity for the latent heat storage material, and a sponge hardness of not more than 50. This achieves stable heat transport with a high heat conversion efficiency even by circulating the medium through a pipeline over a long period of time. The porous material may have continuous pores. The porous material may have a void ratio of not less than 50%. The porous material has an apparent density of about 0.05 to 0.5 g/cm3. The ratio of the latent heat storage material is about 100 to 5000 parts by weight relative to 100 parts by weight of the porous material. The porous material may contain a water-repellent lipophilic resin. The porous material may have a polyorganosiloxane skeleton.

Abstract: Provide are an ionic liquid composition for a carbon dioxide separation membrane, a carbon dioxide separation membrane retaining the composition in voids, and a carbon dioxide concentration apparatus provided with the carbon dioxide separation membrane that can be used to separate carbon dioxide from high partial pressure to low partial pressure. The permeability of CO2 and CO2 selectivity ratio of the carbon dioxide separation membrane can be improved, and carbon dioxide from high partial pressure to a low partial pressure of 1 kPa or lower can be selectively separated and recycled by using an ionic liquid composition prepared by combining: an ionic liquid (I) that is an aminium having one or more primary or secondary amino groups and an ethylenediamine or propylenediamine backbone in the cation; and an ionic liquid (II) in which the cation has no primary or secondary amino group and the anion is an oxoacid anion.

Abstract: A carbon dioxide separation membrane according to the present invention includes: an ionic liquid affinitive porous layer (C) having an ionic liquid-containing liquid (A) retained in voids; and an ionic liquid non-affinitive porous layer (B). The ionic liquid affinitive porous layer (C) may contain inorganic materials (for example, metal oxide particles having an average particle size of about 0.001 to 5 μm on a number basis). An average thickness of the ionic liquid affinitive porous layer (C) may be about from 0.01 to 10 μm. The ionic liquid affinitive porous layer (C) may include the ionic liquid-containing liquid (A) at a ratio from 0.1 to 99 parts by volume with respect to 100 parts by volume of voids. It may be a carbon dioxide separation membrane for fertilizing plants with carbon dioxide. The carbon dioxide separation membrane can reduce a size of the carbon dioxide concentrating device and enables smooth operation of the device.

Abstract: An electrode slurry contains (A) a cellulose fiber and (C) an electrode active material, the electrode active material (C) contains at least a silicon particle and may contain a silicon particle and a carbonaceous particle. The slurry may further contain (B) a carboxymethyl-group-containing cellulose ether or a salt thereof. The average fiber length L (1 to 750 μm) of the cellulose fiber (A) is larger than the average particle size DSi (1 nm to 1 μm) of the silicon particle as the electrode active material (C). The average particle size ratio L/DSi is 5 to 15000. The electrode slurry can improve a discharge capacity and is useful for forming an electrode of a non-aqueous secondary battery (lithium-ion secondary battery) that can maintain a high discharge capacity after repeated charging and discharging.
