Download or read book Novel Hybrid Nanomaterials Based on Polyferrocenylsilane Block Copolymers written by Hai Wang and published by . This book was released on 2008 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polyferrocenyldimethylsilane (PFS) block copolymers self-assemble in selective solvents to form micelles, in which a PFS core is surrounded by a corona of soluble chains. One striking feature of PFS block copolymers is their propensity for forming cylindrical micelles. This thesis focuses on the preparation of novel hybrid nanomaterials using PFS containing cylindrical micelles. These micelles were prepared from PI-b-PFS (PI: polyisoprene) diblock copolymers, or from a new set of PI-b-PFP- b-PFS (PFP: poly(ferrocenylphenylphosphine)) triblock copolymers and PFS-b-P2VP (P2VP: poly(2-vinylpyridine)) diblock copolymers. Specifically, this thesis is classified into the following five parts. Shell-crosslinked PI-b-PFS cylindrical micelles were used as the templates for the preparation of one-dimensional arrays of silver and silver halide nanoparticles. After the PI corona was crosslinked by a Pt(0)-catalyzed hydrosilylation reaction, the PI-b-PFS cylindrical micelles retained their integrity in common good solvents for both blocks. An in-situ redox reaction involving PFS led to silver or silver halide nanoparticles that were confined within the core (PFS) of these micelles. Shell-crosslinked elongated micelles formed by a new type of PFS triblock copolymers, PI-b-PFP-b-PFS, were used to prepare one-dimensional arrays of gold nanoparticles. The phosphorus centers in the polymer backbone were used to introduce Au(I) atoms into the elongated micelles through a coordination reaction. A new class of PFS diblock copolymers, PFS-b-P2VP, was synthesized by sequential anionic polymerization. These polymers showed a remarkable difference in their self-assembly in different alcohol solvents. For example, PFS17-b-P2VP170 with a block ratio of 1: 10 formed spherical micelles in methanol, but gave cylindrical micelles in 2-propanol. The crystallization of the PFS block appears to play a critical role in the formation of the cylindrical micelles. A new type of cylindrical micelles with a B-A-B triblock architecture was created by self-assembly. These structures with positive charges confined to the middle (A) block were obtained by growing PFS-b-P2VP cylindrical micelles off the ends of partially quaternized PFS-b-P2VP seed micelles. Electrostatic interactions were used to selectively functionalize the resulting segmented cylindrical micelles with Au and PbS nanoparticles in a spatially selective manner to afford novel composite structures. Cylindrical PFS17-b-P2VP170 micelles were used in the template-directed synthesis of TiO2 nanowires. The positive charges on coronal quaternized P2VP units effectively directed the deposition of TiO2 via a sol-gel process. The TiO2 coated cylinders were converted to crystalline TiO2 nanowires after calcination.
Download or read book Controlled Synthesis of Polymer Brushes Via Polymer Single Crystal Templates written by Tian Zhou and published by . This book was released on 2015 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: A novel synthetic method of polymer brushes using polymer single crystals (PSCs) as solid-state templates is introduced in this study. PSC has a quasi-2D lamellae structure with polymer chains fold back-and-forth perpendicular to the lamellae surfaces. During crystallization, the chain ends are excluded from the unit cell onto the lamellae surfaces, which makes the material extremely versatile in its functionality. Such structure holds the unique capability to harvest nanoparticles, or being immobilized onto macroscopic flat surfaces. After dissolving PSCs in good solvent, polymer brushes are chemically tethered on either nanoparticles or flat macroscopic surfaces. Because the chain-folding structure can be conveniently tailored by changing the molecular weight of polymer and the crystallization temperature, the thickness, grafting density and morphology of resulted polymer brushes can be precisely controlled. As a model system, poly(Îæ-caprolactone) with thiol or alkoxysilane terminal groups was used, and polymer brushes were successfully prepared on both nanoparticles and glass/Au flat surfaces. The structure-property relationships of the as-prepared polymer brushes were studied in detail using multiple characterization techniques. First of all, when functionalizing nanoparticles, by engineering the chain-folding structure of the PSCs, interesting complex nanostructures can be formed by nanoparticles including Janus nanoparticles and nanoparticle dimers. These unique structures render hybrid nanoparticles very interesting responsive behavior which have been studied in detail in this dissertation. When grafted onto a flat surface on the other hand, not only the molecular weight and grafting density can be precisely controlled, the tethering points of a single polymer chain can also be conveniently tailored, resulting polymer brushes with either tail or loop structures. Such difference in brush structure can significantly alter the properties of functional surface. By using atomic force microscopy based force spectroscopy (AFM-FS) and macroscale shear adhesion measurements, it is thus demonstrated that when polymer loops are grafted, the surface could exhibit much stronger adhesion compared with regular polymer tails when free-dangling polymer chains are allowed to interact with the surface, which is believed to mimic the Velcro-like behavior where polymer loops can withhold strong entanglement with free chain ends upon breaking of the physical bonding.

Download or read book Biomimetic Polymers written by C.G. Gebelein and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: The term biomimetic is comparatively new on the chemical scene, but the concept has been utilized by chemists for many years. Furthermore, the basic idea of making a synthetic material that can imitate the func tions of natural materials probably could be traced back into antiquity. From the dawn of creation, people have probably attempted to duplicate or modify the activities of the natural world. (One can even find allusions to these attempts in the Bible; e. g. , Genesis 30. ) The term "mimetic" means to imitate or mimic. The word "mimic" means to copy closely, or to imitate accurately. Biomimetic, which has not yet entered most dictionaries, means to imitate or mimic some specific bio logical function. Usually, the objective of biomimetics is to form some useful material without the need of utilizing living systems. In a simi lar manner, the term biomimetic polymers means creating synthetic poly mers which imitate the activity of natural bioactive polymers. This is a major advance in polymer chemistry because the natural bioactive polymers are the basis of life itself. Thus, biomimetic polymers imitate the life process in many ways. This present volume delineates some of the recent progress being made in this vast field of biomimetic polymers. Chemists have been making biomimetic polymers for more than fifty years, although this term wasn't used in the early investigations.
