Polymeric nanocomposites made by incorporating small amount of nanoscale inclusions into polymer matrices exhibit dramatic changes in thermomechanical properties over the pure polymers.Stiffness, strength, thermal stability, diffusivity and electrical conductivity all exhibit marked changes over the neat polymer behavior.The properties of the nanoscale fillers can be extraordinary, yet the significant changes observed eannot be due to the nanofillers alone.Enhancing their effect is the extremely significant role that the interphase plays in these systems.Given the enormous surface to volume ratio for nanoparticles, the interphase volume fraction can dwarf that of the inclusions themselves and percolate through the composite.
