The formation of interphases between inorganic nanofillers and polymer matrices is usually known to have a dominant impact on the overall properties of the nanocomposite. Sometimes, multiple chemical and mechanical interphases with different thicknesses coexist in one nanocomposite system. Particularly in thermosetting matrices such as epoxies, the effect of nanofillers on the properties of the matrix is not only limited to the immediate distances, but a long-range chemical alteration in polymer network occurs. In this chapter, first, we investigate the interphase properties of epoxy/boehmite model systems via a combination of atomic force microscopy approaches. Up to the resolution limitations of experimental approaches, long-range mechanical and chemical interphases are visualized via various physical and chemical property mapping of the surface. For investigating short-range interphases with sub-nanometer resolution, we propose a methodological framework to characterize the interphase properties based on molecular dynamic simulations. |
