Abstract: A laminate body is provided, in which two or more organopolysiloxane cured films are obtained by curing curable organopolysiloxane compositions having different compositions because, e.g., the functions required for a dielectric layer and electrode layer are different. In general, problems such as peeling and defects due to insufficient adhesive strength and trackability do not easily occur at an interface between the cured films forming the laminate body. Applications and methods are also provided. The laminate body comprises a structure with two or more laminated organopolysiloxane cured films with different compositions. At least a portion of functional groups involved in the curing reaction are the same. The laminated cured films have structures chemically bonded at an interface thereof.

Abstract: A silicone elastomer cured product having radical reactivity obtained by curing a composition is disclosed. The composition comprises (A) a chain organopolysiloxane having a curing reactive group, and optionally (B) an organohydrogen polysiloxane, (C1) a curing agent, and (D) an organopolysiloxane resin. The surface of the cured product has radical reactivity with, for example, an adhesive, and is easily removable along with, for example, adhesive tape after use as a protective material. In general, the cured product has excellent heat resistance and flexibility and exhibits good adhesion and conformity to a substrate so as not to separate from a substrate even when the cured product is cut together with the substrate while remaining easily removable from the substrate when desired. A protective material for an electronic component made of the cured product is also disclosed.

Abstract: Disclosed is an aluminum-magnesium-silicon composite material that contains an alloy comprising Al, Mg, and Si and can be used favorably as a material for a thermoelectric conversion module, and that has excellent thermoelectric conversion properties. The aluminum-magnesium-silicon composite material contains an alloy comprising Al, Mg and Si, and has an electrical conductivity (?) of 1000-3000 S/cm at 300 K. This aluminum-magnesium-silicon composite material is favorable in the production of a thermoelectric exchange element as a result of having excellent thermoelectric conversion properties.

Abstract: Using a silicon-containing carbon-based composite material represented by the compositional formula: SiOxCyHz. In this formula, “x” is from 0.8 to 1.7, “y” is from 1.4 to 7.5, and “z” is from 0.3 to 1.3. The composite material is preferably obtained by: obtaining a cured product by crosslinking (A) a crosslinkable group-containing organic compound, and (B) a silicon-containing compound capable of crosslinking the crosslinkable group-containing organic compound, and heat treating the obtained cured product. The composite material of the present invention has high reversible capacity and stable charge and discharge cycle characteristics, and has high initial charge and discharge efficiency. Therefore, the composite material of the present invention is suitable for an electrode of an electricity storage device, particularly of a lithium or lithium-ion secondary battery.
