Block copolymer self-assembly and templating strategies
Block copolymers microphase separate to form periodic patterns with period of a few nm and above without the need for lithographic guidance. These self-assembled nanostructures have a variety of bulk geometries (alternating lamellae, gyroids, cylinder or sphere arrays, tiling patterns, core-shell …

Understanding Elastin-Like Polypeptide Block Copolymer Self-assembly Behavior
… where X is any amino acid except proline. ELP diblocks have been engineered by creating two ELP blocks with hydrophilic and hydrophobic guest residues. The hydrophobic block desolvates at a lower temperature and forms the core of a micelle while the still hydrated hydrophilic block forms the …

Block copolymer self-assembly : lithography, magnetic fabrication, and optimization
Block copolymer (BCP) self-assembly is attractive because it provides nanoscale long-range ordered structures in a massive quantity. The capability of generating features with size as low as 5 nm is of particular interest in semiconductor fabrication since current photolithography has reached its …

Block copolymer self-assembly - a computational approach towards novel morphologies
Spontaneous self-assembly of materials is a phenomenon exhibited by different molecular systems. Among many, Block copolymers (BCPs) proved to be particularly interesting due to their ability to microphase separate into periodic domains. Nonetheless, the rising need for arbitrary, complex, 3D …

Nanostructured electrospun fibers : from superhydrophobicity to block copolymer self-assembly
… first part is related to superhydrophobic or "self-cleaning" surfaces. This has been a hot research area due to the wide applications of such materials. Electrospun fibers were first discovered in this dissertation to have sufficient surface roughness for superhydrophobic effect. In contrast to …

Porous Graded Materials Derived From Block Copolymer Self-Assembly For Water And Energy Applications
Block copolymer (BCP) self-assembly provides access to well-ordered nanostructures with tunable morphologies on a typical length scale of 5 - 50 nm. A unique approach combining BCP self-assembly and non-solvent induced phase separation (SNIPS) allows direct formation of graded porous …

Templated self-assembly for complex pattern fabrication
… goal of my Ph.D. study has been controlling the self-assembly of various materials using state-of-the-art nanofabrication techniques. Electron-beam lithography has been used for decades to generate nanoscale patterns, but its throughput is not high enough for fabricating sub-10-nm patterns over a …

Characterization of nano-arrays fabricated via self-assembly of block copolymers
… focused on methods for regulating arrangement of self-assembled block copolymers by understanding fabrication conditions and their effects on the polymers on flat and patterned substrates. Block copolymer self-assembly is a simple and low cost process for creating lithographic masks with features …

Bottlebrush block copolymers for photonic materials
Block copolymer self-assembly has proven to be an effective route for the fabrication of photonic films and, more recently, photonic pigments. However, despite extensive research on this topic over the past two decades, the palette of monomers and polymers employed to produce such structurally …

Self assembly of block copolymers : applicability in microelectronics and gains for patterned media
… integrated with current processing technologies. Block copolymer self assembly promises to do just that. An immiscible block copolymer will microphase separate into individual domains due to unfavorable mixing enthalpy. These microphase-separated blocks can have domain sizes of very low …

Design of silicon-containing block copolymer materials for applications in lithography
… the leading potential methods is to exploit the self-assembly of block copolymers (BCPs). BCPs are a type of polymer consisting of two or more chemically distinct blocks that are covalently joined together. The components of a BCP can phase-separate, and the resultant features form on the 5 to 50 …
