Book Description
Mixed homopolymer brush-grafted nanoparticles, in which two distinct homopolymers randomly or alternatively immobilized by one end on the curved surface of particles, represent a new class of environmentally responsive hybrid materials. The mixed end-tethered polymers can self-assemble into intriguing nanostructures in response to environmental variations. This Ph. D. study focuses on the investigation of nanostructures formed by densely grafted poly(tert-butyl acrylate) (PtBA)/polystyrene (PS) mixed brushes on 67 nm silica nanoparticles in various environmental conditions. As a powerful characterization method, transmission electron microscopy (TEM) was utilized in this research to achieve detailed, three dimensional (3D) nanostructures of polymer brushes. A deeper understanding of the self-assembly of polymer brush-grafted nanoparticles would benefit potential applications of these responsive particles in the nanotechnology field. Chapter 1 introduces the background of this research. Chapter 2 focuses on the 3D hierarchical nanostructures of mixed PtBA/PS brush-grafted 67 nm silica nanoparticles cast from a nonselective good solvent by electron tomography (3D TEM). The interparticle interactions and size distribution of silica cores were found to play a key role in the self-assembly of mixed PtBA/PS brushes in a dense monolayer film of hairy silica nanoparticles. Lacking of interparticle interactions, the individual particles showed unique 3D assembly nanostructures. Chapter 3 focuses on the responsive self-assembly of mixed PtBA/PS brush-grafted 67 nm silica nanoparticles in selective homopolymer matrices. PtBA and poly(cyclohexyl methacrylate) (PCHMA) are two selective homopolymers, which are compatible with PtBA and PS brushes but immiscible with PS and PtBA brushes, respectively. Compared with the uniformly collapsed mixed brushes on silica particles, mixed brushes presented different and responsive assembly structures when blended in various homopolymer matrices. These responsiveness of mixed polymer brushes could be explained by wet- and dry-brush theories. Chapter 4 focuses on the interactions between polymer brush-grafted silica nanoparticles and block copolymers as well as polymer blends. An onion-like structure can form in the low molecular weight diblock copolymer with PtBA homopolymer brush-grafted 67 nm silica nanoparticles or PtBA/PS mixed brush-grafted nanoparticles, where the PtBA brushes are much longer than the PS brushes. In polymer blends, due to either the wet- or the dry-brush effect, hairy particles uniformly dispersed in the preferred domains or segregated in the interfaces. The knowledge gained on hierarchical self-organization of homo and mixed polymer brush-grafted nanoparticles in block copolymer and polymer blend matrices will help us design better polymer nanocomposites with uniform dispersion of nanoparticles.

Book Description
Top-down approaches are currently the main contributor of fabricating microelectronic devices. However, the prohibitive cost of numerous technological steps in these approaches is the main obstacle to further progress. Furthermore, a large number of applications necessitate fabrication of complex and ultra-small devices that cannot be made using these approaches. New approaches based on natural self-assembly of matter need to be developed to allow for fabrication of micro and nanoelectronic devices. Self-assembly of nanostructures is a dynamic field, which explores physics of these structures and new ways to fabricate them. However, the major problem is how to control the properties of the nanostructures resulting from low dimensionality. This book presents recent advances made to address this problem, and fabricate nanostructures using self-assembly.

Book Description
Metamaterials are artificially designed materials engineered to acquire their properties by their specific structure rather than their composition. They are considered a major scientific breakthrough and have attracted enormous attention over the past decade. The major challenge in obtaining an optical metamaterial active at visible frequencies is the fabrication of complex continuous metallic structures with nano metric features. This thesis presents the fabrication and characterization of optical metamaterials made by block copolymer self assembly. This approach allows fabrication of an intriguing and complex continuous 3D architecture called a gyroid, which is replicated into active plasmonic materials such as gold. The optical properties endowed by this particular gyroid geometry include reduction of plasma frequency, extraordinarily enhanced optical transmission, and a predicted negative refractive index. To date, this is the 3D optical metamaterial with the smallest features ever made.

Book Description
Polymers may be classified as either homopolymers, consisting of one single repeating unit, or copolymers, consisting of two or more distinct repeating units. Block copolymers contain long contiguous blocks of two or more repeating units in the same polymer chain. Covering one of the hottest topics in polymer chemistry, Block Copolymers provides a coherent overview of the synthetic routes, physical properties, and applications of block copolymers. This pioneering text provides not only a guideline for developing synthetic strategies for creating block copolymers with defined characteristics, but also a key to the relationship between the physical properties of block copolymers and the structure and dynamics of materials. Covering features of the chemistry and physics of block copolymers that are not found in comparable texts, Block Copolymers illustrates the structure-activity relationship of block copolymers and offers suggestions for the design of specific applications. Divided into five sections-Block Copolymers includes chapters on: * Block Copolymers by Chemical Modification of Precursor Polymers * Nonlinear Block Copolymers * Adsorption of Block Copolymers at Solid-Liquid Interfaces * Theory of Block Copolymer Segregation * Phase Transformation Kinetics * Block Copolymer Morphology * Block Copolymer Dynamics Polymer chemists, physicists, chemical engineers, and materials scientists, as well as graduate students in polymer science, will find Block Copolymers to be an invaluable text.
