Interplay between thermo-mechanical and functional properties of inductively heated nanomagnetite filled shape-memory polymers — •Kazakeviciute-Makovska Rasa and Steeb Holger — Ruhr-Universität Bochum Universitätsstr. 150 D-44780 Bochum

One of the main problems in development of thermo-responsive shape-memory polymer (SMP)-based devices for engineering and medical applications is the design of a safe and effective method of thermal actuation. The conventional method of actuation involves the direct heating. A novel alternative to this method is the inductive heating. This may be achieved by the addition of ferromagnetic particles to a polymer matrix and exposing SMPs to an alternating magnetic field to cause the volumetric and remote heating. Based on the data available in open literature, we discuss the bulk thermo-mechanical and functional properties and performance of nanomagnetite reinforced SMPs. The analysis includes a wide range of filler parameters, induction parameters, and filler distribution configurations with the aim to understand the effects of particle size and shape on the thermal, pseudo-elastic, and rheological properties of this class of SMP nanocomposites. A parallel analysis of the functional behavior of nanomagnetite reinforced shape memory polymers is concerned with the shape fixity and shape recovery properties as well as the maximum recovery stress.
