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.

Polymer surfaces having micro-nanostructures can be produced using injection molding and hot embossing, high efficiency techniques able to meet the needs of industry for the mass production of polymer parts. Micro-nanosurfaces are in great demand for multiple applications that include antipollution and self-cleaning surfaces, microlenses, dry adhesion surfaces, antireflection coatings, cell culturing and differentiation as well as superhydrophobic surfaces. Polymer Surfaces: Fabrication, Modification and Applications discusses the injection molding of micro-nanostructured polymer surfaces consists of three main technical steps: mold inserts, processing parameters and demolding. The authors also discuss the capabilities of various demolding methods, such as antistiction coatings, to protect and enhance the surface properties of micro-nanostructures. The subsequent contribution focuses on biocompatible and biodegradable hollow nanoparticles prepared via the layer-by-layer deposition of polymer thin films on sacrificial templates. The review encompasses all aspects of nanocapsules from preparation through characterization and the applications as drug carriers. A promising strategy is proposed for facilely and successively replicating randomly arranged pyramids on an etched silicon wafer to polystyrene surface. The authors propose that this fast and efficient replication strategy could be an excellent candidate for developing antireflective protective layers without complicated procedures and expensive materials. A promising strategy was proposed for facilely and successively replicating the natural functional nanostructure of the cicada wing onto polystyrene surfaces in the concluding study. This work may direct the design of gradient wetting surfaces by mimicking the nanopillar structure of cicada wing. This strategy could aid in mimicking bio-inspired functional micro/nanostructures without complicated procedures and expensive materials.
