The current report addresses the rheological and viscoelastic properties of poly (trimethylene terephthalate)/polyethylene blend system containing multiwall carbon nanotubes (MWCNTs). The alliance of MWCNT into the blend system raises both the modulus and the dynamic viscosity. The thermophysical properties of blend nanocomposites exhibit a lower threshold percolation particularly in comparison to nanocomposites PTT/MWCNT. The dynamic mechanical properties of nanocomposites were also enhanced by adding MWCNT and the higher storage modulus value of nanocomposites explains their reasonable load—bearing capacity by inserting MWCNT. Reinforcing efficiency factor, degree of entanglement density, coefficient of effectiveness, and volume of the constrained region of blend nanocomposites are studied and 90PTT/10PE/3CNT has shown maximum entanglement density value and reinforcement efficiency factor. Different theoretical models were used to predict the storage modulus of blend nanocomposites and among them, the Takayanagi model established fine concurrence with the experimental results.
