Rheological behavior of Nylon-66/clay nanocomposites based on clay modified in interfacial polycondensation and silane grafting processes

Incorporating finely dispersed layered silicate materials in a polymer matrix have attracted both academic and industrial attention [1]. In these nanocomposites, the study ofrheological properties is instructive for two reasons. First, these properties are indicative of melt processing behavior inunit operations. Second, since the rheological properties of particle-filled materials are sensitive to the structure, particle size, shape and surface characteristics of the dispersed phase,rheology potentially offers a means to assess the state of dispersion in nanocomposites, directly in the melt state [2].Subject of the present contribution is to study the rheological behavior of compounded nylon-66/clay nanocomposites based on clay modified in interfacil polycondensation (IPC) and silane grafting processes.
