A method of forming a metal oxide nanostructure comprises disposing a chelated oligomeric metal oxide precursor on a solvent-soluble template to form a first structure comprising a deformable chelated oligomeric metal oxide precursor layer; setting the deformable chelated oligomeric metal oxide precursor layer to form a second structure comprising a set metal oxide precursor layer; dissolving the solvent-soluble template with a solvent to form a third structure comprising the set metal oxide precursor layer; and thermally treating the third structure to form the metal oxide nanostructure.

摘要:
A method of orienting microphase-separated domains is disclosed, comprising applying a composition comprising an orientation control component, and a block copolymer assembly component comprising a block copolymer having at least two microphase-separated domains in which the orientation control component is substantially immiscible with the block copolymer assembly component upon forming a film; and forming a compositionally vertically segregated film on the surface of the substrate from the composition. The orientation control component and block copolymer segregate during film forming to form the compositionally vertically-segregated film on the surface of a substrate, where the orientation control component is enriched adjacent to the surface of the compositionally segregated film adjacent to the surface of the substrate, and the block copolymer assembly is enriched at an air-surface interface.
摘要:
Nanoparticles in a colloid are purified, with the colloid including a fluid, unwanted matter, and the nanoparticles to be purified. An electric field is applied that is substantially spatially uniform over a distance that is at least equal to a characteristic dimension of the nanoparticles, so that at least some of the nanoparticles move towards at least one collection surface as a result of the force arising between their electrical charge and the electric field, whereupon nanoparticles are collected on said at least one collection surface. The collection surface(s) may be one or more electrodes to which a voltage potential is applied. The collected nanoparticles are then removed from the collection surface, e.g., by dispersing them into another fluid.
摘要:
A first nanoscale self-aligned self-assembled nested line structure having a sublithographic width and a sublithographic spacing and running along a first direction is formed from first self-assembling block copolymers within a first layer. The first layer is filled with a filler material and a second layer is deposited above the first layer containing the first nanoscale nested line structure. A second nanoscale self-aligned self-assembled nested line structure having a sublithographic width and a sublithographic spacing and running in a second direction is formed from second self-assembling block copolymers within the second layer. The composite pattern of the first nanoscale nested line structure and the second nanoscale nested line structure is transferred into an underlayer beneath the first layer to form an array of structures containing periodicity in two directions.
摘要:
Substantially or roughly spherical micellar structures useful in the formation of nanoporous materials by templating are disclosed. A roughly spherical micellar structure is formed by organization of one or more spatially unsymmetric organic amphiphilic molecules. Each of those molecules comprises a branched moiety and a second moiety. The branched moiety can form part of either the core or the surface of the spherical micellar structure, depending on the polarity of the environment. The roughly spherical micellar structures form in a thermosetting polymer matrix. They are employed in a templating process whereby the amphiphilic molecules are dispersed in the polymer matrix, the matrix is cured, and the porogens are then removed, leaving nanoscale pores.

摘要:
A nanoporous material exhibiting a lamellar structure is disclosed. The material comprises three or more substantially parallel sheets of an organosilicate material, separated by highly porous spacer regions. The distance between the centers of the sheets lies between 1 nm and 50 nm. The highly porous spacer regions may be substantially free of condensed material. For the manufacture of such materials, a process is disclosed in which matrix non-amphiphilic polymeric material and templating polymeric material are dispersed in a solvent, where the templating polymeric material includes a polymeric amphiphilic material. The solvent with the polymeric materials is distributed onto a substrate. Organization is induced in the templating polymeric material. The solvent is removed, leaving the polymeric materials in place. The matrix polymeric material is cured, forming a lamellar structure.
