Zhang, Wenwen published the artcileSynthesis of cross-linked triple shape memory polyurethane with self-healing functionalities, Recommanded Product: 2,2′-Dithiodibenzoic acid, the publication is Polymer Testing (2021), 107099, database is CAplus.
A series of shape memory polymers (SMPs) comprising poly (10-hydroxydecanoate) (PHDA) and polyethylene glycol (PEG) oligomer were facilely prepared The effect of PEG content on the thermal dynamic properties of the crosslinking network were studied by differential scanning calorimetry (DSC) and dynamic mech. anal. (DMA). The obtained polyurethane has two separated melting temperatures (Tm), which make the material a triple SMP. The shaped specimen only needs 8 s to get a 98.5% the shape recovery. Furthermore, disulfide bonds were introduced into the polyurethane to give the triple SMP self-healing ability. The synthetic polymer exhibited a self-healing efficiency of 78.3%. The healed samples could lift a weight of 100 g, which is 150 times of its own weight, without tearing. This polyurethane exhibits impressive triple-shape memory ability and a high potential for biomedical applications.
