Effect of Selective Localization and Migration of Inorganic Nanoparticles on Morphology and Properties of Polymer Blends

The solid particles are well known to distribute unevenly in polymer blends and the factors that determine their distribution are discussed. The present review aims at summarizing the current knowledge on the phase behavior, phase morphology, mechanical property, electrically property, rheological behavior, crystallization, melting behaviors and optical property of polymer blends/layered silicate nanocomposites. A particular emphasis is given on how to control the particle localization in polymer blends through the competition between thermodynamic wetting of the solid by the polymeric phases as well as the kinetics related to the rate of mixing.
