Aligned Carbon Nanotube Patterning Via Dry Contact Transfer Printing

Aligned Carbon Nanotube Patterning Via Dry Contact Transfer Printing

The approach of transferring CNT thin films from one surface to another via a soft lithography technique suffers from limited ability to achieve good adhesion of the CNT films to the transferred substrate and imprecise alignment of the CNT patterns. A transfer technique that can be scaled to large area with high throughput processing at low temperature is being reported in this paper, ...

High-yield dielectrophoretic assembly of two-dimensional graphene nanostructures

High-yield dielectrophoretic assembly of two-dimensional graphene nanostructures

The serial mechanical exfoliation method available can not be used for the assembly of graphene in the large scale. In this process, deposition of ultrathin few-layer (three to ten) graphene oxide, with parallel and controllable assembly, by dielectrophoresis between prefabricated electrodes has been demonstrated.

Fabrication of a nanoporous template from a diblock copolymer film - electric field alignment

Fabrication of a nanoporous template from a diblock copolymer film - electric field alignment

An applied electric field aligns a cylindrical-phase diblock copolymer perpendicular to a substrate. One polymer block is removed by UV exposure and a chemical rinse to yield a nanoporous polymer film. The porous film can be used as a template for electrodeposition of metal nanowires or as a mask for reactive ion etching.

Fabrication of a nanoporous template from a diblock copolymer film - neutral brush

Fabrication of a nanoporous template from a diblock copolymer film - neutral brush

A perpendicular orientation of cylindrical microdomains in diblock copolymer thin films is achieved by control over polymer-surface interactions. The block which forms cylindrical microdomains is removed by UV exposure and a chemical rinse to yield a nanoporous polymer film. The porous film can be used as a template for electrodeposition of metal nanodots or as a mask for reactive ion etching.

Fabrication of a nanoporous template from a diblock copolymer film - solvent annealing

Fabrication of a nanoporous template from a diblock copolymer film - solvent annealing

An evaporation-induced flow in solvent cast block copolymer films can produce arrays of nanoscopic cylinders oriented normal to the surface and solvent annealing could markedly enhance the ordering of block copolymer microdomains in thin films. Without removing minor components, solvent-induced surface reconstruction can produce nanoporous structure in thin films. The porous film can be used as ...

Wrinkles

Wrinkles

Four thin films of varying thickness are wrinkled by a .2mg drop of water. As the films increase in thickness, the number of wrinkles caused by the droplets decreases while the length of the wrinkles increases.
