- In this article, the authors present their point of view on whether an analogy can be drawn between nano and classical microcomposites. Their opinion corresponds with a 25-year-old opinion article by Calvert and is based on their own extensive studies and a large body of studies in the scientific literature. They propose that polymer nanocomposites are in fact quasi-homogeneous molecular blends, which ought to be regarded as molecular composites or self-reinforced polymers. Hence, the micromechanical models of classical composites may not generally apply to nanocomposites, where—instead—the interactions on a molecular scale between the nanoparticles and the polymer matrix control the properties. A few examples, including of nucleation and confinement by nanoparticles, are discussed.
