Book Synopsis Biomimetic Polymers by : C.G. Gebelein
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.

Modification of polysaccharides through graft copolymerization improves the properties of polysaccharides. Grafting is known to improve the characteristic properties of the backbones. Such properties include water repellency, thermal stability, flame resistance, dye-ability and resistance towards acid-base attack and abrasion. Polysaccharides and their graft copolymers find extensive applications in diversified fields. Applications of modified polysaccharides include drug delivery devices, controlled release of fungicides, selective water absorption from oil-water emulsions, purification of water etc.
Book Synopsis Interface Structure of Photonic Films Created by Plasma Enhanced Chemical Vapor Deposition by : Someswara R. Peri
Download or read book Interface Structure of Photonic Films Created by Plasma Enhanced Chemical Vapor Deposition written by Someswara R. Peri and published by . This book was released on 2010 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plasma polymerized (PP-) films offer several advantages over conventionally deposited polymeric films including good adhesion to a variety of substrates and bulk cross-linked structures. However, several facets of the structure of these commercially important materials have received almost no systematic study. There were three key objectives for this work. The first was to understand how the formation of the interfaces of a single layer by plasma enhanced chemical vapor deposition (PECVD) impacts the width and type of interface formed between layers in a multilayer system. The second objective was to determine whether the cross-link density in PECVD deposited films is uniform through the depth of the film and, if not, how it varies with depth. The final objective was to map out how both interface structure and crosslink density uniformity are impacted by the important parameters of monomer feed position, plasma power, and reactor pressure. In pursuing these objectives, PP-homopolymer films, PP-bilayer films, and PP-copolymer single layer films were studied. Changes in the structure of PP-homopolymer films with processing parameters were investigated using X-ray reflectivity (XR) and neutron reflectivity (NR). For ultrathin PP-homopolymer films (less than 200 [angstrom]) deposited under 45 W power and 0.6 and 0.05 torr reactor pressures, variations in structure with depth near the substrate and near the surface were much more readily apparent than in thick films. Thin PP homopolymer films (greater than 250 [angstrom]) deposited at 30 W power and 0.6 torr reactor pressure showed no variations in structure with depth1. A transition region next to the substrate in which the structure varies markedly, over a very small depth, was also observed for both PP-octafluorocyclobutane (OFCB) and PP-benzene (BZ) films. Variations in the cross-link density with processing pressure were much stronger for PPBZ films than for PP-OFCB films. Measurements of films swollen with solvent vapor revealed that each film had a thin layer (1-1.5 nm) of lower cross-link density next to the substrate and a layer (1.5-3.0 nm) of lower cross-link density next to the air where the vast majority of the swelling took place. The thickness of the region of lower cross-link density at the surface reflects the extent of a reaction zone that moves with the deposition and is responsible for dictating the width of interfaces that are formed when a layer of different precursor is deposited atop the first layer. Changes in film structure caused by "copolymerization" with a second precursor to form PP-copolymer films were investigated using X-ray reflectivity (XR). Copolymer films made from comonomers BZ, OFCB, and hexamethyldisiloxane (HMDS) showed extremely sharp interfaces and scattering length density depth profiles that were uniform with depth. Addition of either benzene or HMDS as a comonomer in the deposition of OFCB diminished the transient deposition behavior at the silicon oxide interface that occurs when using only OFCB. For the B-OFCB copolymer films, a facile control of refractive index with monomer feed composition was achieved. A peak in the X-ray scattering length density and nonlinear visible light refractive index (633nm) with composition was observed for the HMDS-OFCB copolymer film.
