To investigate the electroactive shape-memory property of the hydro-epoxy composites, a sample with 1.9 wt% carbon black powder is investigated. The figure shows that the recovery of the original shape occurred after only a few minutes. Moreover, the shape recovery ratio (Rr) of the electroactive shape-memory hydro-epoxy composite is almost 100%. This finding indicates good electroactive shape-memory performance.
