2148 results about "Hybrid material" patented technology

Hybrid materials are composites consisting of two constituents at the nanometer or molecular level. Commonly one of these compounds is inorganic and the other one organic in nature. Thus, they differ from traditional composites where the constituents are at the macroscopic (micrometer to millimeter) level. Mixing at the microscopic scale leads to a more homogeneous material that either show characteristics in between the two original phases or even new properties.

Uniform surfaces for hybrid material substrate and methods for making and using same

Devices, systems and methods of using same where hybrid substrate materials are provided with a substantially uniform surface to provide uniformity of properties, including interaction with their environments. Uniform surfaces are applied as coatings over, e.g., hybrid metal / silica, metal / polymer, metal / metal surfaces to mask different chemical properties of differing regions of the surface and to afford a protective surface for the hybrid structure.
