  • Publication number: 20190085148
    Abstract: A mixture of silicone elastomer and carbonyl iron powder is disclosed, with the silicone elastomer being able to bind the iron powder in weight percents between 75 and 90 while surprising retaining an elastomeric hardness of between about 40 and 70 on the Shore A scale. The isotropic iron powder provides thermal conductivity and magnetism to the silicone elastomer which can be formed during crosslinking into any final shape desired.

  • 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: 20110204351
    Abstract: The present invention relates to polymers comprising a repeating unit of the formula (I) and their use in electronic devices. The polymers according to the invention have excellent solubility in organic solvents and excellent film-forming properties. In addition, high charge carrier mobilities and high temperature stability of the emission color are observed, if the polymers according to the invention are used in polymer light emitting diodes (PLEDs).

  • Publication number: 20110006272
    Abstract: Highly active and durable electrochromic films are prepared with good thickness control in the nanometer range by alternate application of a metal salt solution and a solution of a ?-conjugated polymer having metal complexing side chains, for example, polymers having side chains comprising terpyridine (tpy) groups. Thus a robust, crosslinked organo-metallic network of a known, desired thickness with excellent electroactive properties is readily prepared.
