Block 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 کاملBlock 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 کاملAmphiphilic Block Copolymer Nano-micelles: Effect of Length Ratio of the Hydrophilic Block
Block copolymer nano-micelles are especially important in cancer treatment because of their fine dimensions. In this article, three systems of amphiphilic copolymers with similar lengths and different ratios of the hydrophobic and hydrophilic chains are studied using implicit-solvent coarse-grained molecular dynamics simulations. The factor fphil is defined as the ratio of the number...
متن کاملScanning probe block copolymer lithography.
Integration of individual nanoparticles into desired spatial arrangements over large areas is a prerequisite for exploiting their unique electrical, optical, and chemical properties. However, positioning single sub-10-nm nanoparticles in a specific location individually on a substrate remains challenging. Herein we have developed a unique approach, termed scanning probe block copolymer lithogra...
متن کاملBlock Copolymer/Water/Oil Mesophases
In the presence of selective solvents, amphiphilic block copolymers self-assemble and form different mesomorphic structures, known as mesophases, such as micellar cubic, lamellar, normal/reverse hexagonal, and bicontinuous cubic. Mesophases have been utilized in pharmaceutical and biomedical applications and as template for synthesis of mesoporous material for separation and adsorption processe...
