Book Description
Two-dimensional self-assemblies of plasmonic nanoparticles (NPs) could one day become a useful technology for mankind as it has a potential to produce desirable structures with various patterning and ordering that is difficult to achieve by the top-down approach. Furthermore, these patterned and ordered structures of NPs have been known to display interesting optoelectronic properties. While applications using self-assemblies of plasmonic NPs seem promising, the fundamental forces that govern the evolution of these structures are not fully understood yet. Interesting similarities between the interfacial NP self-assembly and epitaxial growth exist despite a number of differences such as diffusion, desorption, coalescence, and ordering. The goal of this dissertation is to determine to what extent established submonolayer epitaxy theories can be applied to modeling interfacial NP self-assembly, and thereby develop new tools for understanding NP-NP interactions and self-assembly. Different sizes of 1-dodecanethiol (DDT) capped Au NPs were used to study the submonolayer growth behavior of NP islands. However, for the study, synthesizing DDT Au NPs> 8 nm by a conventional method was a challenge. To solve this synthesis problem, large NPs were synthesized in water and a phase transfer-based method was developed and used. While solving this synthesis problem, we developed general guidelines for NP phase transfer and determined that successful phase transfer only depended on three key surfactant parameters: bulkiness, length, and ability to get onto the interface. Furthermore, we also shed light on the mechanistic details of NP phase transfer into the organic medium. The experimental results for the submonolayer growth study such as NP island size distribution (ISD), capture zone distribution (CZD), percolation threshold, diffusion, and flux were compared and contrasted with the known epitaxy theories. It was found that islands were compact and circular at low coverages, while at high coverages they were blobby and irregular due to coalescence. In addition, the critical nucleus size (i) was found to depend on NP size. Surprisingly, it was also found that for smaller NPs, ISDs and CZDs were described better by a Gamma function rather than the proposed scaling forms for the ISDs and CZDs. In stark contrast with epitaxy, interesting yet puzzling behavior of island ordering (due to a long-range repulsive interaction among islands) was also observed. We proposed that this repulsive interaction was due to a dipole-dipole interaction that could originate from an anisotropic distribution of thiol molecules around the NPs at the liquid-air interface. This idea was supported by Monte Carlo simulations that take into account dipole-dipole interactions.

Book Description
An introduction to the state-of-the-art of the diverse self-assembly systems Self-Assembly: From Surfactants to Nanoparticles provides an effective entry for new researchers into this exciting field while also giving the state of the art assessment of the diverse self-assembling systems for those already engaged in this research. Over the last twenty years, self-assembly has emerged as a distinct science/technology field, going well beyond the classical surfactant and block copolymer molecules, and encompassing much larger and complex molecular, biomolecular and nanoparticle systems. Within its ten chapters, each contributed by pioneers of the respective research topics, the book: Discusses the fundamental physical chemical principles that govern the formation and properties of self-assembled systems Describes important experimental techniques to characterize the properties of self-assembled systems, particularly the nature of molecular organization and structure at the nano, meso or micro scales. Provides the first exhaustive accounting of self-assembly derived from various kinds of biomolecules including peptides, DNA and proteins. Outlines methods of synthesis and functionalization of self-assembled nanoparticles and the further self-assembly of the nanoparticles into one, two or three dimensional materials. Explores numerous potential applications of self-assembled structures including nanomedicine applications of drug delivery, imaging, molecular diagnostics and theranostics, and design of materials to specification such as smart responsive materials and self-healing materials. Highlights the unifying as well as contrasting features of self-assembly, as we move from surfactant molecules to nanoparticles. Written for students and academic and industrial scientists and engineers, by pioneers of the research field, Self-Assembly: From Surfactants to Nanoparticles is a comprehensive resource on diverse self-assembly systems, that is simultaneously introductory as well as the state of the art.

Book Description
Dispersions of nanoparticles in polymer matrices form hybrid materials that can exhibit superior structural and functional properties and find applications in e. g. thermo-plastics, electronics, polymer electrolytes, catalysis, paint formulations, and drug delivery. Control over the particle location and orientation in the polymeric matrices are essential in order to realize the enhanced mechanical, electrical, and optical properties of the nanohybrids. Block copolymers, composed of two or more different monomers, are promising for controlling particle location and orientation because of their ability to organize into ordered nanostructures. Fundamental questions pertaining to nanoparticle-polymer interfacial interactions remain open and formulate the objectives of our investigation. Particle-polymer enthalpic and entropic interactions control the nanoparticle dispersion in polymer matrices. Synthetic chemical methods for modifying the particle surface in order to control polymer-particle interactions are involved and large scale production is not possible. In the current approach, a physical method is employed to control polymer-particle interactions. The use of commercially available solvents is found to be effective in modifying particle-polymer interfacial interactions. The approach is applicable to a wide range of particle-polymer systems and can thereby enable large scale processing of polymer nanohybrids. The systems of silica nanoparticles dispersed in long-range or short-range self-assembled structures of aqueous poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) (PEO-PPO-PEO) block copolymers (Pluronics) is considered here. The effect of various parameters such as the presence of organic solvents, pH, and particle size on the block copolymer organization and the ensuing particle-polymer interactions are investigated. Favorable surface interactions between the deprotonated silica nanoparticle and PEO-rich domain facilitate particle incorporation in the cylindrical lyotropic mesophase formed by hydrated PEO-PPO-PEO block copolymer. The amount of nanoparticle dispersed is limited to 10 wt% due to restrictions posed by a combination of thermodynamics and geometry. Incorporation of deprotonated nanoparticles by replacing equal mass of water did not affect the lattice parameter of the hexagonal lyotropic liquid crystalline structures formed by hydrated PEO-PPO-PEO block copolymer. The incorporation of protonated NPs resulted in an increase in the lattice parameter due to stronger nanoparticle-polymer enthalpic interactions. Two dimensional swelling exponent (d ~ Φpolymer-0. 65) suggests that deprotonated nanoparticles are located inside the PEO-rich domains, away from PEO-PPO interfaces. The presence of organic solvents screen the effect of protonated NPs on the lattice parameter of the hexagonal lyotropic liquid crystalline structures formed by hydrated PEO-PPO-PEO block copolymer.
