Abstract:This review paper summarizes the recent research progress in the underlying mechanisms behind the shape memory effect (SME) and some newly discovered shape memory phenomena in polymeric materials. It is revealed that most polymeric materials, if not all, intrinsically have the thermo/chemo-responsive SME. It is demonstrated that a good understanding of the fundamentals behind various types of shape memory phenomena in polymeric materials is not only useful in design/synthesis of new polymeric shape memory materials (SMMs) with tailored performance, but also helpful in optimization of the existing ones, and thus remarkably widens the application field of polymeric SMMs.

“…SMPs are similar to other actively responsive polymers, of which a change in properties results from an external stimulus, such as heat, light, electricity and so on (Lendlein, 2010;Hu and Chen, 2010;Luo and Mather, 2010). This also includes a combination of two or more responses at the same time.…”

“…(Leng, 2009). With the practical and potential applications of SMPs increasing, some major limitations impose many challenges to their broad utilisation, such as the low thermal conductivity and inertness to electromagnetic stimuli (Luo and Mather, 2010). By this motivation, a variety of approaches for the electrical actuation of SMPs have been developed, and have led to the recovery of SMP composites being induced by electrically resistive Joule heating through incorporation of electrically conductive fillers, such as carbon nanotubes, carbon particles, conductive fibre, nickel zinc ferrite ferromagnetic particles, etc.…”

“…Most of the current research in the field of SMPs is focused on the intrinsic function of the SME, functional composite, the exploitation of different stimuli as triggers and demonstration of potential application (Ma et al, 2013;Bellin et al, 2006;Tobushi et al, 2008;Lu et al, 2009;Lu et al, 2010;Luo and Mather 2010;Lantada et al, 2010;Le et al, 2011;Lu et al, 2011b;Lu et al, 2011a;Fejos et al, 2012;Lu 2012a;Lu 2012b;Fejos and Karger-Kocsis 2013;Lu et al, 2013;Lu et al, 2013c;Lu et al, 2014b).…”

Purpose -The study reported here intended to create and to study multifunctional shape memory polymer (SMP) composite having temperature sensing and actuating capabilities by embedding thermochromic particles within the polymer matrix.Design/methodology/approach -The multifunctional materials were fabricated following a process consisting of blending (of the thermochromic particles and the SMP at various ratios), mixing, degasing, moulding and thermal curing, thus incorporating thermochromic particles within the polymer. The effect of the thermochromic particles on the thermomechanical properties and thermally responsive shape memory effect (SME) of the resulting multifunction SMP composites were characterised and interpreted.Findings -It was found that exposure of the composites to temperatures above 70°C led to a pronounced, reproducibly reversible change of their colour that was recorded by the thermal and electrical actuation approaches. It was also found that the colour of the composites was independent of the mechanical state of the SMP. Such effects enabled monitoring of the onset of the set/release temperature of the SMP matrix. Furthermore, the combination of thermochromic additive and the SMP resulted in significantly improved thermomechanical strength, absorption of infrared radiation and temperature distribution of the SMP composites.1 Corresponding author, e-mail: yaoyt@hit.edu.cnResearch implications -The temperature sensing and actuating capabilities of the polymeric shape memory composites developed through this study will help to extend the field of potential applications of such composites to fields including sensors, actuators, security labels and information dissemination, where colour indication is an advantageous feature.Originality/value -The shape memory polymer (SMP) composites capable of temperature sensing and actuating are novel.
