摘要： [Problem]
To provide a laminated body in which two or more organopolysiloxane cured films obtained by curing curable organopolysiloxane compositions having different compositions because the functions required for a dielectric layer and electrode layer are different, and in which 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; and an application and manufacturing method thereof. [Solution] A laminate body, comprising a structure with two or more laminated organopolysiloxane cured films with different compositions where at least a portion of functional groups involved in the curing reaction are the same, wherein the laminated cured films have structures chemically bonded at an interface thereof. Preferably, the compositions both contain a hydrosilylation reactive group, and the SiH/Vi ratio in the compositions differ, with the laminated cured films having structures chemically bonded by hydrosilylation reactions at an interface thereof.

摘要： [Problems] To provide a curable organopolysiloxane composition which can be easily processed into a film shape and has a high specific dielectric constant, high dielectric breakdown strength, and a low Young's modulus, allowing for a high energy density to be achieved, in addition to having excellent mechanical strength (specifically, tensile strength, tear strength, elongation percentage, etc.) when used as a dielectric layer in a transducer, along with the use thereof.
[Resolution Means] Provided are: a fluoroalkyl group-containing curable organopolysiloxane composition which can be cured by an addition reaction and which is obtained using an organopolysiloxane containing an alkenyl group and a fluoroalkyl group; an organohydrogen polysiloxane having SiH at both terminals of a molecular chain but not having a fluoroalkyl group; and a linear fluoroalkyl group-containing organohydrogen polysiloxane or a branched fluoroalkyl group-containing organohydrogen polysiloxane having T units; along with the use thereof.

摘要： [Problem] To provide a laminate having a gel layer on a substrate able to protect the substrate during various types of processing used in industrial production steps prior to curing, the gel layer having excellent heat resistance, softness and flexibility, a low modulus of elasticity, low stress, excellent stress buffering properties, and electronic component retention properties, and the gel layer having higher shape retention before curing but changing after curing into a hard layer having excellent release properties, the laminate being easily and readily releasable from the substrate even when the cured layer is localized, and to provide applications thereof (such as an electronic component manufacturing method). [Solution] A laminate comprising a laminated reaction-curable silicone gel and a sheet-like member laminated via an adhesive layer on top of the reaction-curable silicone gel, and a use thereof.
