Shape memory-based multifunctional structural actuator panels
A multifunctional panel concept is presented in which a lightweight, structural sandwich panel is able to undergo a reversible change in shape upon application of a localized thermal stimulus. The shape change is effected by metallic (or polymeric) shape memory (SM) face sheet elements, which exploit a “one-way” SM effect only. Unlike other designs, no external or bias forces are required to co...
متن کاملPolyaniline Modified Nanocellulose as Reinforcement of a Shape Memory Polyurethane
In this work, electrically conductive cellulose nanocrystals were used to reinforce shape memory polyurethanes, adding an extra variable to tune up the properties of these nanocomposites. The modified nanocrystals were prepared by an in situ polymerization method, growing polyaniline (PANI) on the surface of the cellulose nanofibrils [3]. These crystals combine the good mechanical properties of...
متن کاملMultifunctional polyurethane-vitrimers completely based on transcarbamoylation of carbamates: thermally-induced dual-shape memory effect and self-welding
Environmental protection and resources exhaustion have become the two major obstacles that the human race faces. Moreover, conventional thermoset polymers, which have been extensively applied in various fields, are difficult to be reprocessed and recycled thereby resulting in a wastage of resources and environmental pollution owing to their chemical crosslinks. Therefore, vitrimers may be a goo...
متن کاملPolyurethane shape-memory polymers demonstrate functional biocompatibility in vitro.
Shape memory polymers (SMPs) are a class of polymeric materials used in various medical interventions such as vascular stents. In this work, two SMPs, thermoplastic (TP) and thermoset (TS), have been measured in vitro for the degree of cellular and protein adhesion, their ability to stimulate inflammatory cytokine production, as well as the effects of the SMPs on the haemostatic system. The sti...
متن کاملShape xity and shape recovery of polyurethane shape-memory polymer foams
The thermomechanical properties of polyurethane shape memory polymer (SMP) foams were investigated experimentally. The results obtained can be summarized as follows. (1) By cooling the foam after compressive deformation at high temperature, stress decreases and the deformed shape is xed. Stress decreases markedly in the region of temperature below the glass transition temperature Tg during th...
