  • Patent number: 10034955
    Abstract: The invention relates to the production of a pressure-sensitive adhesive composition polymerized entirely from acrylate-based monomers in a layer thickness of about 250 ?m and to the use thereof for adhesion to human skin. The adhesive films thus produced adhere reliably to human skin, have high water-vapor permeability despite the layer thickness, with the result that, for example, wound healing is promoted, and even after a relatively long wearing period can be removed from the skin again without leaving a residue and without damaging the skin.

  • Publication number: 20150086799
    Abstract: An organic polymer solution may include about 0.1%-30% by weight of a specific polymer having rigid rod-like molecules. These molecules may include various cores, spacers, and sides groups to ensure their solubility, viscosity, and cross-linking ability. The rigid rod-like molecules are selected in such a way that they form self-assembling structures in the polymer solution, which makes it a lyotropic liquid crystal. The organic polymer solution, when properly deposited on a substrate and dried to remove solvents, forms a solid optical retardation layer of positive A-type substantially transparent to electromagnetic radiation in the visible spectral range.

  • Patent number: 7829155
    Abstract: The present invention provides a new monomer and methods of using the monomer to fabricate robust polymer surface coatings with controlled thicknesses between 1 and 5 nanometers. The coatings are composed of a new material containing polymerized monomers of 4-vinylbenzenepropanethiol. The polymer surface coating may be applied to metal and silicon. The method includes exposing a metal substrate to a solution of the monomer in hexanes in order to deposit a monolayer of the monomer onto the metal surface. The substrate is then irradiated with ultraviolet radiation in order to graft a thin polymer coating onto the surface. The procedure can be repeated in order to control the thickness of the coating between about 1 nm and 5 nm. Alternatively, thermally initiated polymerization or deposition of partially oligomerized monomers onto the surface provides nanothin coatings with identical performance.
