摘要:
A self-replicating monolayer system employing polymerization of monomers or nanoparticle ensembles on a defined template provides synthesis of two-dimensional single molecule polymers. Systems of self-replicating monolayers are used as templates for growth of inorganic colloids. A preferred embodiment employs SAM-based replication, wherein an initial monolayer is patterned and used as a template for self-assembly of a second monolayer by molecular recognition. The second monolayer is polymerized in place and the monolayers are separated to form a replicate. Both may then function as templates for monolayer assemblies. A generic self-replicating monomer unit comprises a polymerizable moiety attached by methylene repeats to a recognition element and an ending unit that will not interfere with the chosen recognition chemistry. The recognition element is self-complementary, unless two replicating monomers with compatible cross-linking chemistry are employed. After replication, selective mineralization and/or electroless plating may produce a two-dimensional inorganic sheet having patterned domains within it.

A process for forming nanostructures comprises generating charged nanoparticles with an electrospray system and introduction of the charged nanoparticles to a substrate, so that the particles adhere to the substrate in order to form the desired structure. The charged nanoparticles may be directed to a target position by at least one deflector in the electrospray apparatus, which may also include a column optic system. The adhered nanoparticles may be sintered to form the structure. The electrospray apparatus may be single source, multi-source injection, or multi-source selection. An array of electrospray apparatuses with deflectors may be used concurrently to form the structure.

A method for manufacturing a full color, reflective display includes the steps of depositing a first plurality of electrophoretic display elements in substantial registration with a first electrode and a second plurality of electrophoretic display elements in substantial registration with a second electrode. The electrophoretic display elements include a capsule containing a species of particles dispersed in a suspending fluid. The selective deposition of the display elements can be achieved by ink-jet printing methods, screen printing methods or other printing methods. In some embodiments the electrodes are printed onto the substrate before selective deposition of the display elements, while in other embodiments the substrate is provided having the electrodes already disposed on it. In still other embodiments, the sequence of printing of electrodes and electrophoretic display elements can be varied.

A generic self-replicating monomer unit comprises a polymerizable moiety attached by methylene repeats to a recognition element and an ending unit that will not interfere with the chosen recognition chemistry. The recognition element is self-complementary, unless a set of two replicating monomers with compatible cross-linking chemistry is employed. In a two-component replication system utilizing two different kinds of recognition chemistries, the initial template undergoes replication cycles, while maintaining two-dimensional segregation of the two types of monomers. During subsequent replications, the component domains experience little or no mixing, allowing the two-component, patterned assembly to be exponentially replicated. After replication, selective mineralization and/or electroless plating may produce a two-dimensional inorganic sheet having patterned domains within it.

Disclosed herein are novel electrophoretic displays and materials useful in fabricating such displays. In particular, novel encapsulated displays are disclosed. Particles encapsulated therein are dispersed within a suspending, or electrophoretic, fluid. This fluid may be a mixture of two or more fluids or may be a single fluid. The displays may further comprise particles dispersed in a suspending fluid, wherein the particles contain a liquid. In either case, the suspending fluid may have a density or refractive index substantially matched to that of the particles dispersed therein. Finally, also disclosed herein are electro-osmotic displays. These displays comprise at least one capsule containing either a cellulosic or gel-like internal phase and a liquid phase, or containing two or more immiscible fluids. Application of electric fields to any of the electrophoretic displays described herein affects an optical property of the display.
