Determination of polymer–nanoparticles interfacial adhesion and its role in shape memory behavior of shape memory polymer nanocomposites

In this paper, various micromechanics models are applied to evaluate the interfacial characteristics between the matrix and the nanofiller phases in shape memory polymer nanocomposites (SMPNs). The models analyze the interfacial adhesion by yield strength and tensile modulus of several SMPNs from literature. In addition, the effect of interfacial adhesion on the shape memory behavior of SMPNs is discussed. lculated parameters by modeling process demonstrate an acceptable interfacial bonding in the reported SMPNs. It is confirmed that the SMPNs, which show a good shape memory behavior, include a strong adhesion at the polymer–nanofiller interface.
