    摘要： Provided is an ultra-thin elastomer sheet that is composed of silicone, can stand alone, and can be put to practical use.
    The ultra-thin elastomer sheet is an ultra-thin sheet, which has a maximum film thickness of 3 µm and is composed of a crosslinked silicone polymer in which a silicone polymer configured from a plurality of unit portions having reactive organic groups and a plurality of unit portions not having reactive organic groups is crosslinked by a crosslinking agent having a reaction group that reacts with the reactive organic groups,
    the crosslinked silicone polymer is defined by the following mathematical formula (I)
    [mathematical expression 1] U = Um + Un / Ua where, in mathematical formula (I), U is a number of monomer unit portions between crosslinking points of the crosslinked silicone polymer, Um is a number of monomer unit portions of the silicone polymer that do not have reactive organic groups, Un is a number of monomer unit portions of the silicone polymer that have reactive organic groups, and Ua is a number of reaction groups of the crosslinking agent used in crosslinking and
    the number of monomer unit portions between crosslinking points of the crosslinked silicone polymer is 348-2090.

    摘要： The present disclosure provides a single-component silica gel medium suitable for direct ink writing 3D printing, a preparation method and application thereof. A viscosity of the single-component silica gel medium is 200 to 1000 Pa·s, and a viscosity change value of the single-component silica gel medium is less than and equal to 10% after the single-component silica gel medium is stored at room temperature for more than 30 days. The preparation method of the single-component silica gel medium includes the following steps of mixing polysiloxane containing carbon-carbon double bonds, a tackifier, and a platinum catalyst to obtain a first mixture; heating the first mixture and holding for first time, and adding a polymerization inhibitor and holding for second time to obtain a second mixture; cooling the second mixture, and mixing the second mixture with hydrogen-containing polysiloxane to obtain a third mixture; mixing the third mixture with an inorganic nano-filler to obtain a fourth mixture; and performing vacuum defoamation and filtration under pressure on the fourth mixture sequentially. The single-component silica gel medium is particularly suitable for the high-precision printing of micron-sized lines in the field of direct ink writing 3D printing.

    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.
