  • Patent number: 9478727
    Abstract: A dielectric elastomer has a film that contains a fluorinated silicone elastomer and has two faces. A coating of a stretchable electrode material is applied to each one of the two faces. The fluorinated silicone elastomer has a modulus of elasticity of maximally 450 kPa. The fluorinated silicone elastomer is a three-dimensionally crosslinked, fluorinated, alkyl group-containing polysiloxane in combination with a fluorinated silicone oil. Alternatively, or in addition, the fluorinated silicone elastomer is a three-dimensional wide-mesh crosslinked, fluorinated, alkyl-group containing polysiloxane whose wide mesh property has been effected by a chain length extension by addition of a chain-shaped silicone molecule containing two Si—H groups to an alkenyl group-containing polysiloxane molecule.

  • Publication number: 20120015576
    Abstract: The invention relates to a planar or shaped textile material comprising or constituted of fibers, at least part of the fibers being coated with a hydrolytically condensed inorganic/organic hybrid material having single-walled or multi-walled carbon nanotubes which are embedded therein, optionally covalently bound thereto. The carbon nanotubes are preferably functionalized, especially with carboxylic acid groups or sulfanilic acid groups. The textile material is suitable for producing protective clothing, barrier materials or the like. The invention further relates to the use of the above-defined hybrid material as a coating material which imparts stain-resistance and/or antimicrobial properties to the coated substrate.
