*2.6. Thermomechanical Characterization of PLA Formulations Plasticized with MBNO and MHO*

To analyze the changes in storage modulus (G') and damping factor, a dynamic thermo-mechanical analysis (DMTA) was performed with an oscillatory rheometer AR G2 from TA Instruments (New Castle, DE, EEUU), equipped with a clamp attachment for solid samples. The 40 <sup>×</sup> <sup>10</sup> <sup>×</sup> 4 mm<sup>3</sup> rectangular samples were tested in torsion mode and subjected to a thermal program from 30 ◦C to 130 ◦C with a heating rate of 2 ◦C·min−<sup>1</sup> . The frequency was set at 1 Hz and the maximum deformation (*γ*) was 0.1%.
