Abstract: Aspects disclosed herein include a composite material comprising: one or more shape memory polymers; and a first additive provided in the shape memory polymer(s); wherein: the first additive increases one or more ultrasound-absorption characteristics of the composite material compared to that of the same shape memory polymer(s) free of said first additive; the composite material is characterized by a composite transition temperature (Tcm,trans); and the composite material or one or more portions thereof undergo a shape change from a temporary shape to a permanent shape when the composite material or said one or more portions thereof are heated to within 35° C. of Tcm,trans or a temperature approximately equal to or greater than Tcm,trans.
