“…The investigation of the structure, chain conformation, and dynamics of polymer nanocomposites (PNCs) constitutes a very active research area due to the innovative properties of these materials, which make them candidates for a broad range of applications. − The properties of polymer chains close to the surface of a nanoadditive or under confinement are different compared to those in the bulk, affecting the overall behavior of the systems. − Important advances both in basic research ,,,,, and in different industrial fields have been made on hybrid polymer–nanoparticle systems. − Moreover, a number of computational, ,− experimental, − ,,,,,,− and combined studies , have been employed to investigate the effects of the presence of the interfaces on the properties of the polymer, providing a measure of the interphase length. ,,,,− …”
