Effect of the addition of organically modified nanofiller on the relaxation behavior of a thermoplastic amorphous matrix

▸ We measured the relaxation of PETg nanocomposites with organically modified montmorillonite. ▸ We found that the nanocomposite has a faster relaxation than neat matrix. ▸ Stress relaxation tests provided lower value of the relaxation time for the nanocomposite. ▸ The faster relaxation of nanocomposite is attributed to plasticizing effect of the organic modifier.
