Over 30% of commercial polymers are blends or alloys or one kind or another. Nanostructured blends offer the scientist or plastics engineer a new range of possibilities with characteristics including thermodynamic stablility; the potential to improve material transparency, creep and solvent resistance; the potential to simultaneously increase tensile strength and ductility; superior rheological properties; and relatively low cost. Nanostructured Polymer Blends opens up immense structural possibilities via chemical and mechanical modifications that generate novel properties and functions and high-performance characteristics at a low cost. The emerging applications of these new materials cover a wide range of industry sectors, encompassing the coatings and adhesives industry, electronics, energy (photovoltaics), aerospace and medical devices (where polymer blends provide innovations in biocompatible materials). This book explains the science of nanostructure formation and the nature of interphase formations, demystifies the design of nanostructured blends to achieve specific properties, and introduces the applications for this important new class of nanomaterial. All the key topics related to recent advances in blends are covered: IPNs, phase morphologies, composites and nanocomposites, nanostructure formation, the chemistry and structure of additives, etc. Introduces the science and technology of nanostructured polymer blends – and the procedures involved in melt blending and chemical blending to produce new materials with specific performance characteristics Unlocks the potential of nanostructured polymer blends for applications across sectors, including electronics, energy/photovoltaics, aerospace/automotive, and medical devices (biocompatible polymers) Explains the performance benefits in areas including rheological properties, thermodynamic stablility, material transparency, solvent resistance, etc.

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 can be induced. We also examine the main areas in which multiscale-ordered interfaces obtained from polymer blends have been applied.

The exceptional properties of nanoheterogeneous materials result both from the nature of each component, the size scale, the degree of mixing between the two phases, and the surface area-to-volume ratio. Therefore, significant performances of the resulting materials can be reached by tailoring the interfaces. Due to their features, nanoheterogeneous materials have been involved in a plethora of niche markets linked, for instance, to new generations of smart textiles, photovoltaic and fuel cells, antennas and satellite communications, optoelectronics, new catalysts and coatings, smart therapeutic vectors with controlled drug delivery properties, new ultrasensitive sensors, cosmetics, smart papers, and so on. The chapter is an overview of the current state of knowledge in processing, manufacturing, characterization, and potential applications of the most common polymer nanocomposites, with a special attention to their utilizations in gas sensing.

Until about 30 years ago all carbon-based polymers were regarded strictly as insulators, and hence were extensively utilized by the electronics industry for this very property. They have been used as inactive packaging and insulating material. This very narrow perspective has rapidly changed with the emergence of intrinsically conducting polymers. The combination of conventional polymers with conductive polymers or fillers is an important alternative to obtaining new polymeric materials with designed properties. Through the combination of conventional polymers with conductive polymers such as polyaniline, polypyrrole, and so on, the mechanical properties of conducting polymers can be improved. The insulating polymer removes the brittleness and lack of processibility that are the main drawbacks hindering conducting polymers. Blend applications require that conductivity is achieved at a small weight fraction of conducting polymer. There is also an increased requirement for polymeric materials whose electrical conductivity can be tailored. The aim this chapter is to describe conducting polymer blend systems to identify characteristic trends that might be useful for the investigation of their potential application in various electronic and optoelectronic devices.
