Abstract:
A method and structure that forms a multilayer nanoparticle thin film assembly begins by functionalizing a substrate with functional molecules. Next, the invention replaces a stabilizer on a bottom surface of the first nanoparticles with the functional molecules via surface ligand exchange to make a first nanoparticle layer on the substrate. The invention then replaces the stabilizer on a top surface of the first nanoparticle layer with functional molecules via surface ligand exchange. The invention replaces the stabilizer on a bottom surface of the second nanoparticles with the functional molecules via surface ligand exchange to make a second nanoparticle layer on the first nanoparticle layer. Lastly, the invention repeats the previous steps and forms additional nanoparticle layers.
Abstract:
A method for enhancing the bond strength between a VDF-containing fluoroplastic layer and an elastomer layer of a multi-layer article. A VDF-containing fluoroplastic composition is applied to the surface of a precursor article that includes a curable elastomer layer to form a fluoroplastic layer. Prior to application of the fluoroplastic composition, the curable elastomer layer is thermally insulated to prevent it from undergoing substantial heating. Following application, the fluoroplastic layer is heated and the curable elastomer layer is cured (e.g., thermally cured). Preferably, the elastomer cure occurs separately from and subsequent to heating the fluoroplastic layer. The combination of thermally insulating the curable elastomer layer prior to application of the fluoroplastic composition and heating the fluoroplastic layer following application of the fluoroplastic composition results in formation of a strong bond between the fluoroplastic and elastomer layers upon cure.

The transparent substrate such as glass is made hydrophobic and free of contamination.
Abstract:
A method for manufacturing a gravure transfer-coated continuous metal plate, wound in the form of a coil, comprising: coating, over the metal plate, a primer coating material; curing the primer coating material to form a lower coating layer; thermally transferring a desired pattern from a gravure transfer sheet onto the lower coating layer, thereby forming a transfer coating; coating, over the transfer coating, an upper coating material of thermosetting fluorine resin, thermosetting polyester resin, or UV-thermosetting polyurethane-acryl-based resin; and curing the upper coating material to form an upper coating layer. The primer coating material consists essentially of: 20-40% polyester resin having a number average molecular weight of 5,000-20,000 and a glass transition temperature of 10-50° C., 4-15% melamine resin, 1-10% urethane resin, 0.3-3% isocyanate, 15-35% pigment 30-50% hydrocarbon/ester-based mixed solvent, and 1.5-3% additives.
