Block copolymer nanostructures
JUN-AUG 2008 | VOLUME 3 | NUMBER 3-4 38 Block copolymers occupy a huge area of research because they offer a vast range of possibilities for architecture, size, and chemical composition. Advances in polymer chemistry1, such as anionic polymerisation2 and most recently living radical polymerization3, have enabled a vast array of block copolymers to be synthesized with great control over their ar...
متن کاملBlock Copolymer Nanostructures for Technology
Nanostructures generated from block copolymer self-assembly enable a variety of potential technological applications. In this article we review recent work and the current status of two major emerging applications of block copolymer (BCP) nanostructures: lithography for microelectronics and photovoltaics. We review the progress in BCP lithography in relation to the requirements of the semicondu...
متن کاملBlock copolymer nanostructures mapped by far-field optics.
We demonstrate stimulated emission depletion microscopy using opposing objective lenses to noninvasively reveal the nanoscale morphology of block copolymers in three dimensions with focused light. This is exemplified in a poly(styrene-block-2-vinylpyridine) model system in which contrast is achieved by specifically staining the vinylpyridine phase with a fluorescent dye. We image swelling induc...
متن کاملBlock copolymer micelle nanolithography
Au-nanoclusters between 2 and 8 nm in diameter were deposited onto solid substrates in different pattern geometries. The basis of this approach is the self-assembly of polystyrene-b-poly[2-vinylpyridine (HAuCl4)] diblock copolymer micelles into uniform monomicellar films on solid supports such as Si-wafers or glass cover slips. HAuCl4 as metallic precursor or a single solid Au-nanoparticle caus...
متن کاملCovalent Stabilization of Nanostructures: Robust Block Copolymer Templates from Novel Thermoreactive Systems
Structurally robust block copolymer templates with feature sizes of approximately 10 nm were prepared from functionalized poly(methyl methacrylate)-b-polystyrene block copolymers. By the inclusion of benzocyclobutene crosslinking groups in the polystyrene block, the covalent stabilization of thin films to both thermal treatment and solvent exposure became possible. In addition, the crosslinking...
