In a classical one-way shape-memory effect, the first stage is the definition of a shape-shifting pathway using external physical manipulation, termed programming (Fig. 1). Of note, a shape change introduced during the fabrication process, for example, by lithography, should not be viewed as programming, … Visa mer Shape-memory behaviour in polymeric systems relies on the controlled storage of entropic energy, the subsequent release of which drives the shape change. The entropic energy is generated by conformational … Visa mer In a two-way reversible shape-memory effect, a bidirectional reversible actuation is enabled by conformational changes of the pre-oriented actuating polymer segments within the … Visa mer During a one-way shape-memory effect, the thermal energy derived from external temperature increase causes a phase change, for example, by overcoming the melting enthalpy of … Visa mer WebbThe shape fixity ratio is 98.5% and the shape recovery ratio is 88.3%. It is noted that both the shape fixity ratio and shape recovery ratio are slightly lower than those in the first …
