Modeling of viscoelastic behavior of a shape memory polymer blend
Abstract
<jats:title>Abstract</jats:title><jats:p>Shape memory effect (SME) of polymers is a property that concerns both, macroscopic and microscopic changes. The variation of internal polymer properties such, as molecular weight (<jats:italic>M</jats:italic><jats:sub>w</jats:sub>), rigidity, and viscoelasticity could alter its SME. In this study, a bi‐parabolic model with six parameters is used to describe the viscoelastic behavior of a shape memory polymer (SMP) blend (40% poly(caprolactone), PCL/60% Styrene–Butadiene–Styrene) with different PCL <jats:italic>M</jats:italic><jats:sub>w</jats:sub>. These parameters are determined using the Cole–Cole method. Modeling curves (<jats:italic>E</jats:italic>″ = <jats:italic>f</jats:italic> (<jats:italic>E</jats:italic>′)) will be then compared to experimental data from dynamical mechanical analysis (DMA) tests. It is shown that the bi‐parabolic model predicts well the behavior of the SMP mixture for different <jats:italic>M</jats:italic><jats:sub>w</jats:sub> of PCL. Afterwards, the evolution of the model parameters with the <jats:italic>M</jats:italic><jats:sub>w</jats:sub> of PCL is investigated. It is revealed that, when <jats:italic>M</jats:italic><jats:sub>w</jats:sub> of PCL drops, the relaxation modulus <jats:italic>E</jats:italic><jats:sub>0</jats:sub> increases. This result proves that the rigidity of the SMP blend rises with <jats:italic>M</jats:italic><jats:sub>w</jats:sub> declines.</jats:p>
