Formation and transfer mechanism of the interfacial phase in nanocomposites. In nanocomposites, the polymer chains can adsorb on the surface of nanoparticles due to various interactions, which greatly limit chain motion. The adsorbed chains form many “loop” structures, which provide effective sites for entanglement with the surrounding polymer chains. The interphase is formed by infiltration of the surrounding chain into the adsorbed chain. The relaxation of polymer chains in the bulk is influenced by the entanglement transfer of the interphase, which improves the macroscopic mechanical properties of nanocomposites.
