Transfer of Mechanical Stress from Polymer Matrix to Nanofiller in Dispersion-Filled Nanocomposites

—The effect of changing structural characteristics of a particulate nanofiller during its aggregation on the degree of transfer of the mechanical stress applied to the sample from the polymer matrix to the nanofiller has been studied. The properties of particulate-filled nanocomposites are controlled by the quality of the stress transfer rather than the characteristics of the starting nanofiller. The stress transfer is sharply reduced because of the aggregation of nanofiller particles.
