  • Patent number: 11629049
    Abstract: The present invention relates to a method for producing a molded body (10), comprising the following steps: a) providing a molding tool (40) which has at least one receptacle (12) in which at least one material (30) which comprises at least one shape-memory material (31) is introduced, wherein the shape-memory material (31) is present in a first state (111), wherein the material (30) at least partially fills the receptacle (12) of the molding tool (40) in such a manner that said material adjoins at least one surface of the receptacle (12); b) creating a molded body (10) in the receptacle (12) of the molding tool (40) from the material (30), wherein the shape-memory material (31) is present in a second state (112), wherein a form (11) is embossed into the molded body (10) during the second state (112); c) transferring the shape-memory material (31) to a third state (113), wherein the molded body (10) can be deformed during the third state (113) in such a manner that the molded body (10) is demolded from the

  • Publication number: 20170348614
    Abstract: A molded body includes a shape memory material. The molded body has a three-dimensional surface structure which, in a permanent shape, at least in part has a superhydrophobic surface and/or a hydrophobic surface, on which water droplet contact angles of 120° to 150° are found.

  • Patent number: 9738029
    Abstract: A method for producing a molded body includes providing a composite including a first plate having a polymer film pressed into its surface, providing a third plate including roughened areas on at least part of one of its surfaces, placing the third plate opposite the polymer film without the third plate touching the composite, heating the third plate to a temperature above the glass transition temperature Tg of the polymer of the polymer film without heating the composite and without the heated third plate coming into contact with the surface of the polymer film, and structuring the surface of the polymer film facing the third plate by a relative movement which removes the third plate from the first plate while the polymer film remains soft and is thus extended lengthwise, thereby forming a modified composite that comprises the molded body.
