Abstract (sommario):
Block copolymers are receiving increasing attention in the literature. Reports on amphiphilic block copolymers have now established the basis of their self-assembly behavior: aggregate sizes, morphologies and stability can be explained from the absolute and relative block lengths, the nature of the blocks, the architecture and also solvent selectiveness. In water, self-assembly of amphiphilic block copolymers is assumed to be driven by the hydrophobic. The motivation of this thesis is to study the influence on the self-assembly in water of A b B type block copolymers (with A hydrophilic) of th

Il drug delivery attira molto interesse a causa della necessità di migliorare efficienza e selettività delle terapie farmacologiche. Capsule polimeriche per i farmaci sono una strategia promettente per prolungarne i tempi di circolazione, migliorarne il trasporto nel sangue, e modularne nel tempo il rilascio. In questo ambito, l’organizzazione spontanea dei copolimeri a blocchi (CB) in nanoparticelle (NP) compartimentalizzate in ambiente acquoso è uno strumento potente per la fabbricazione di sistemi per il drug delivery.

Our group has shown that crystallisation-driven self-assembly (CDSA) of P3AT and P3ASe block copolymers (BCPs) in block-selective solvents allows access to colloidally-stable nanofibers with π-conjugated cores. In this thesis, we demonstrate that the contour length of P3ASe nanofibers can be controlled using a seeded-growth technique.

Abstract (sommario):
Nanofabrication has been long characterized by a top-down approach for the definition of small features starting from large pieces of material. In this contest the process of size scaling in microelectronics devices is based on photolithography that is an advanced top-down technology. In order to design integrated circuits with small features with characteristic dimension below 20 nm, a new kind of approach is needed such as the bottom-up one of self-assembly systems. Indeed symmetric block copolymers are able to spontaneously phase separate into ordered nanoscale lamellar pattern, which can b

Abstract (sommario):
In the present work we have synthesized two-component block copolymers MOPEO-b-PААm and PААm-b-PЕО-b-PААm comprised methoxypoly(ethylene oxide), poly(ethylene oxide) and chemically complementary polyacrylamide. These copolymers we used as special matrices in the process of borohydride reduction of Ag+ ions. It was established the influence of chemical nature, molecular architecture and concentration of the matrices and the content of silver nitrate on some reaction parameters, size and stability of Ag-nanoparticles in aqueous solutions.

Thesis: Ph. D., Massachusetts Institute of Technology, Department of Materials Science and Engineering, 2017.<br>Cataloged from PDF version of thesis.<br>Includes bibliographical references.<br>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 resolution limitation and the other competing technologies are either too slow such as e-beam lithography or

博士<br>國立清華大學<br>化學工程學系<br>96<br>The self-assembly of synthetic supramolecules has been inspired by using the secondary interactions, and has already created a large number of nanoscale architectures. Among self-assembled architectures, helical morphology is probably the most fascinating morphologies in nature. Chirality of compounds has been referred to one of the main origins for the formation of helical textures. For the self-assembly of block copolymers (BCPs), one-, two-, or three-dimensional periodic nanostructures can be easily tailored by molecular engineering of synthetic BCPs. By taki

碩士<br>國立清華大學<br>化學工程學系<br>93<br>The interaction of polycation-DNA can form complexes with DNA resulting in the coil–globule conformational transition in the DNA molecules and DNA condensation. It was proposed that polycation-DNA complex formation is entropy driven and electrostatic force due to the ion pairs formed between positively charged groups of polycation molecule and the phosphate groups of DNA. In our studies, we try to use cationic diblock copolymer and homopolymer as polycations, and complex with DNA to investigate the actual internal structure. This is more one parameter in cationi
