摘要:
An electrically conductive coating composition is provided for use on aircraft and other substrate surfaces to prevent the formation of ice or to melt ice. The conductive coating composition may include a nanomaterial such as carbon nanotubes dispersed in a solvent which may be applied to a substrate surface to form a thin film which is resistively heatable. The conductive coating may also comprise a nanomaterial formed from carbon nanotubes or fullerenes grafted to a polymer containing an active functional group which renders a substrate surface icephobic and is also resistively heatable.

Verwendung eines substratgestützten Polymerfilms als Oberflächenbeschichtung von Faser-Kunststoff-Verbundbauteilen, die nach dem Crushed-Core-Verfahren aus Verbundaufbauten mit einem Kern und mindestens einer Prepreg-Auflage hergestellt sind, wobei der Polymerfilm vor dem Aushärten des Verbundaufbaus und ggf. vor dessen Einformen harzseitig auf eine Prepreg-Oberfläche aufgebracht wird und das Aushärten unter Druckeinwirkung und erhöhter Temperatur erfolgt. Der substratgestützte Polymerfilm umfasst eine Harzmatrix mit einem Vernetzungsgrad unterhalb ihres Gelpunktes, welche hergestellt ist aus mindestens einem di- oder polyfunktionellen aromatischen organischen Cyanat und mindestens einem di- oder polyfunktionellen aromatischen Alkohol in Mengenanteilen, die ein molares Verhältnis der OCN-Gruppen zu OH-Gruppen in den Ausgangsmaterialien zur Herstellung des Prepolymeren zwischen 95:5 und 70:30 gewährleisten, sowie mindestens einem Füllstoff.

The invention is directed toward systems and methods for the formation of two dimensional monolayer structures of ordered biomacromolecules, such as viruses, atop cohesive polyelectrolyte multilayers to create functional thin films. Methods for the formation of such thin films are disclosed that involve an interdiffusion-induced assembly process of the biomacromolecules. The inventive systems provide a general platform for the systematic incorporation and assembly of organic, biological and inorganic materials and will enable many potential technological applications such as, for example, chemical and biological sensors, power devices and catalytic membranes.
