[资源] FUNCTIONAL POLYMER BLENDS Synthesis, Properties, and Performance

Preface
Polymer blends constitute a very important class of materials where the
components are either physically or chemically mixed with each other to
achieve a certain set of functional properties. The physical means of compatibilization
of the phases in the blends are addition of compatibilizers
(viz. polyethylene-
co-maleic anhydride), whereas chemical means include
chemical reactions with the phases for chemical linking. Polymer blends are
widely used materials in the modern polymer industry because of their wider
range of properties as compared to the individual polymers and their ease
in tailoring of properties. As a result, polymer blends find applications in
numerous fields such as adhesion, colloidal stability, design of composite
and biocompatible materials, and so forth. The science and technology of
polymer blends has gained tremendous developments in the recent years.
A large number of polymer blend systems have been reported along with
further developments on their means of synthesis, microstructure, and properties
characterization. These functional polymer blend systems have helped
to further enhance the application spectrum of polymers in general. The current
book proposes to provide these advances in synthesis and characterization
methodologies for the generation of different polymer blends systems.
Chapter 1 provides an introduction as well as overview of the polymer
blend systems. A number of examples of functional polymer blends have been
demonstrated. Chapter 2 provides information on the miscibility enhancements
in polymer blends through multiple hydrogen binding interactions.
Chapter 3 presents the component dynamics prevailing in polymer blend
systems. The dynamic environment differs for respective components, thereby
giving rise to a difference of the segmental relaxation time of these components
in both magnitude and temperature dependence. Concepts of shape
memory polymer blends are presented in Chapter 4.
A shape memory polymer (SMP) is a smart material that can memorize
its original shape after being deformed into a temporary shape when it is
heated or receives any other external stimuli such as light, electric field,
magnetic field, chemical, moisture, and pH change. Ethylene methyl acrylate
(EMA) copolymer toughened polymethyl methacrylate (PMMA) blends have
been detailed in Chapter 5. Along with synthesis, extensive characterization
of the blends for thermal, mechanical, optical, and morphological properties
has been reported. Chapter 6 provides theoretical insights through molecular
dynamics simulation studies for binary blend miscibility. Calculation
of some important parameters, such as Flory Huggins parameter, solubility
parameter, and glass transition temperature to discuss the compatibility
of polymers has been presented. Chapter 7 reports on conformation and
topology of cyclic linear polymer blends (CLBs). The bond fluctuation model
