Abstract:
The invention provides materials and methods for forming coatings on substrates. The coatings are durable and resistant to damage from environmental, chemical, thermal, and/or radiative sources. In some embodiments, the coatings comprise bilayers of electrostatically charged materials. The bilayers are created by alternately applying solutions comprising water-soluble, electrostatically charged materials. Durability is imparted to the coatings by the formation of crosslinks that are formed within and between layers after deposition of the coatings.
Abstract:
The invention concerns in particular a method for depositing a nanometric multilayer thin film on a substrate from a liquid solution containing at least one surfactant. The method includes the following steps: forming a film from the solution; contacting the substrate; and depositing the film on the substrate. The invention is particularly formed to enable depositing black films on different types of surfaces, in particular for obtaining highly organized films. The films obtained by the method are particularly useful in electronics and optics.

Abstract:
The invention addressed a difficult problem in the conventional methods and has its object to provide an organic thin film with flexibility and high strength to be a support for a molecule, with which a biomolecular element or a molecule such as a membrane protein as a biosensor can function equally in a living body, and a method for producing the same. In this invention, the organic thin film to be a support for the biomolecular element or the biosensor molecule is produced by forming a layer of lipid molecules on a layer of fatty acid molecules which is a primary thin film layer formed on an inorganic substrate. Further, by the selection and combination of fatty acid molecules, a thin film structure with a characteristic pattern structure can be obtained.

Abstract:
Langmuir-Blodgett films are provided in which a molecule is chemically bonded with a bottom electrode substrate as part of a crossed wire device comprising two electrodes and a molecular layer therebetween. The molecule, which comprises a switchable moiety and a connecting moiety, is provided with a photolabile capping group attached to the connecting moiety. The photolabile capping group temporarily caps the reactive connecting group of the molecule. The capped molecules are processed to form a LB film on the water-air interface of water. The films are then exposed to UV light. The photolabile capping group decomposes to give back the connecting group, which remains in the water. As the uncapped LB films are transferred to a bottom electrode substrate, the surface of the electrode reacts with the reactive connecting group of the molecule to form a chemically bonded LB layer on the substrate, thereby providing improved LB films.
Abstract:
A method is disclosed of three-dimensional (3D) free-form printing for coating free-form objects, the method including: arranging a free-form object in a Langmuir-Blodgett (LB) trough filed with a liquid, the LB trough designed based on a shape of the free-form object; arranging an LB film comprising a plurality of colloidal nanospheres on a surface of the liquid within the LB trough; and draining the liquid from the LB trough to form a self-assemble film of the colloidal nanoparticles on a surface of the free-form object.
