Nanostructured Polymer Blends Excerpt :

Nanofillers can play two important roles in polymer blends. The first is the improvement of various properties such as mechanical, barrier, thermal, flame retardancy, and electrical properties. The second is the modification of miscibility/compatibility and morphology of polymer blends. The mechanism of action of nanoparticles to modify the morphology, interfacial properties, and performance of immiscible polymer blends relies on their localization, their interactions with polymer components, and the way these additives disperse within the polymer blend. The objective of this chapter is to review the research on nanofilled thermoplastic/thermoplastic polymer blends, paying particular attention both to the distribution of nanoparticles inside a binary polymer blend and to the effect of nanofillers on the morphology and on the properties of the thermoplastic polymer blends. In a large majority of cases, thermoplastic polymer blends filled with nanoparticles show better compatibility in terms of morphology size than pure blends. Moreover, the formation of a cocontinuous structure is promoted by the presence of the nanofiller.

Nanostructured Polymer Blends Excerpt :

Great progress has been made in the science and technology of polymer-based nanomaterials over the last decade. Nanostructured polymer systems have attracted much scientific and applied research interest. The last two decades have witnessed significant advances in polymer science and technology generally, but more so for polymer blends. The idea of blending two (or more) polymers, especially immiscible blends, has come with a lot of challenges. Achieving this has brought to the fore the art and science (and engineering) of compatibilization. During the last few decades, the addition of nanoparticles, nanowires, nanotubes, and so on has advanced even further the creation of blends, alloys, and composites with different polymers. In making these blends, intermediaries such as compatibilizers, coupling agents, and other additives are often employed to bring about blends that are satisfactory for the purposes they are intended to serve. Nanostructured polymer blends formation has strongly improved the properties and structural integrities of polymer blends, by employing compatibilization as a tool to achieve such properties and structural integrities of polymer blends. Reinforcing compatibilized polymer blends with nanosize additives has further strengthened the properties and integrities of polymer blends, alloys, and composites.

Nanostructured Polymer Blends Excerpt :

The design of polymer blends constitutes an interesting alternative to obtaining micro- and nanostructured surfaces. The cost is reasonable and it is free from time-consuming procedures. Blending of polymers can yield materials with unprecedented properties that cannot be provided otherwise by using a single polymer. The free surface topography of polymer blend films, often related to phase domain structure, is critical to the applications. Two main aspects need to be considered in the preparation of multistructured blends: the interfaces involved and the morphology to be obtained. The control of these two aspects depends further on materials-related parameters involving the composition of the blend, the interfacial tension or viscosity ratio, and the processing conditions related to the temperature, time, or intensity of mixing, among others. Both domain structure and topography of the blend films have garnered increasing interest over the past decade. This chapter describes the nanomicrostructures formed at the polymer surface from polymer blends. Despite the crucial role that surfaces play in the final application of the material, up to now most of the studies concerning polymer blends have been related to the control of the mechanical properties (toughness, stiffness, thermal expansion, etc.), their barrier properties, or the electrical conductivity. This chapter focuses on the analysis of the structured polymer surfaces and thin films, giving an overview of the role of these structures on the final application. The principles of phase separation and the resulting structures formed are briefly discussed, followed by a wide overview of the possibilities of producing stimuli-responsive interfaces by introducing, among other things, pH- or temperature-responsive polymers within the blend. Finally, we look at how using particular preparation conditions and/or self-assembly of block copolymers, the formation of films and surfaces with hierarchical order length-scales

Nanostructured Polymer Blends Excerpt :

Miscibility and compatibility in polymer blends is a topic of great academic and industrial importance. This is because miscibility and compatibility contribute to morphology, properties, and performance. Miscibility results in one phase; compatibility creates a disperse phase with size and stability determined by interfacial interactions. Miscible polymer properties are averaged similar to a plasticizer polymer, and compatible polymers retain properties of each component, such as toughening or reinforcement. With miscible polymer blends the continuous phase dominates properties; the disperse phase contributes via stress transfer. This chapter revisits the criteria for miscibility or compatibility in polymer blends and the contributors of compatibility compared with miscibility and incompatibility. Development of copolymers and their blending with thermosets and thermoplastics result in complex two-phase morphologies. The dynamics of phase separation observed in polymer blends leading to different morphologies and the criteria for phase separation is explained. A nanometer-dispersed phase requires strong interfacial interactions to stabilize the large interfacial area, and this is favored by rapid spinodal phase separation compared with size diminution by high shear. Nanoblends open up a new arena for polymer blends, and research shows that nanoblends have outstanding optical and mechanical properties.

Nanostructured Polymer Blends Excerpt :

The engineering of nanostructured thermosets with different modifiers has generated significant interest, since improved overall properties are promised by good control over monodispersed microdomains. Incorporation of block copolymers and hyperbranched polymers are acknowledged as two efficient strategies to build up such nano/microcomposites, bearing distinct phase-segregating behaviors owing to respective unique architectures. In this chapter, we aim to illustrate the interplay between matrix and modifier from a perspective of thermodynamics. The two most common mechanisms of thermoset/block copolymer demixing are interpreted; most obtained morphologies of thermoset/hyperbranched polymers are broadly correlated to the width of the phase-separation conversion window. General preparation methods as well as time-temperature-transition diagrams are given to guide practice. Thermal, mechanical, and dynamic properties are covered, with an emphasis on how the formation of various nanostructures actually influences these properties.

Nanostructured Polymer Blends Excerpt :

The usefulness of any material, including nanocomposite polymer blends, depends on its degradability and durability. Thus, this chapter reviews the status of the research on degradation of nanocomposite polymer blends and, in particular, on clay-nanocomposite polymer blends, paying particular attention to both the role of the filler and the role of the blend morphology and composition. The results of recent research indicate that the clay has two opposing effects on the thermal stability of a nanocomposite polymer blend: (1) a promoter effect of the polymer matrix degradation, which decreases the thermal stability, and (2) a barrier effect, which improves the thermal stability. Moreover, the presence of organoclays generally reduces the photostability of nanocomposite polymer blends. Despite the effect of the filler, blend morphology and blend composition can significantly affect, either positively or negatively, the degradation behavior of the polymer blend nanocomposites.

Nanostructures Synthesis Functional Properties and Application Excerpt :

The Advanced Study Institute on Synthesis, Functional Properties and Applications of Nanostructures, held at the Knossos Royal Village, Heraklion, Crete, Greece, July 26, 2002 - August 4, 2002, successfully reviewed the state-of-the-art of nanostructures and nanotechnology. It was concluded that Nanotechnology is widely agreed to be the research focus that will lead to the next generation of breakthroughs in science and engineering. There are three cornerstones to the expectation that Nanotechnology will yield revolutionary advances in understanding and application: • Breakthroughs in properties that arise from materials fabricated from the nanoscale. • Synergistic behavior that arise from the combination of disparate types of materials (soft vs. hard, organic vs. inorganic, chemical vs. biological vs. solid state) at the nanoscale. • Exploitation of natural (e.g. chemical and biological) assembly mechanisms that can accomplish structural control at the nanoscale. It is expected that this will lead to paradigms for assembling bio-inspired functional systems that accomplish desirable properties that are either unavailable or prohibitively expensive using top-down approaches.
