摘要:
Shape-memory-polymers (SMPs) have displayed many attractive features, especially in some shape memory composites that are able to respond swiftly to one or multiple particular stimuli. An intriguing application of the electrically stimulated SMPs is that they have the capability to be remotely actuated by which their primary shape is recovered. The present paper has represented a comprehensive discussion on the recent progress of electro-activated SMP composites from the perspective of microstructure, fabrication-process, mechanisms, and performance. Moreover, the other primary focus is on the most recent studies on 4D-printing of SMPs that are incorporated by conductive carbon- and metal-based particles, as well as hybrid ones. Although 4D SMPs have been extensively accepted as smart materials, numerous fundamental weaknesses and major limitations have been still existing from the engineering aspects. In this review, a systematic approach is adopted to highlight the progression and challenges of conductive SMPs and the pivotal research areas.
