Microphase classification

Abstract The present paper discusses classification of nano-objects, which is based on their size, morphology and chemical nature. The subject of nanochemistry includes those nano-objects whose chemical properties depend on size and morphology, such as spheroidal molecules, anisotropic (2D) and isotropic (ID) nanoparticles, nano-clusters and nanophases. Nanophase is a nano-dimensional part of the microphase whose properties depend on its size. The potential health hazards of nano-objects are associated with their capability of penetrating the body through inhalation, digestion or the skin. [Pg.23]

As a result of the microphase separation occurring above the critical micelle concentration, different nanostructures can be observed. Blends of homopolymer and copolymer (A/A-B) exhibit different morphologies that have been described first by Hashimoto et al. [2,3,36], who proposed a classification in terms of solubility of the copolymer brushes by the homopolymer. On the basis of these reports, De Gennes [37] and Gallot et al. [6] further investigated the structure formation in binary polymer blends. These studies established that the final morphology depends on the molecular weight of the homopolymers in the blend. As depicted in Fig. 6.4, four different situations have been described [2,3,36] ... [Pg.135]
