Shape memory behavior was applied here as a new approach for developing the latent photopatterned morphologies in two/three dimension (2D/3D) on the modified poly(styrene-block-butadiene-block-styrene) (SBS). By attaching anthracene groups onto the SBS chains, the elastomer frozen in the deformed state was photopatterned via the photodimerization of anthracene. Upon thermal treatment, shape memory process could effectively develop the latent photopatterning induced 2D–2D and 2D–3D shape transformation. Due to the reversible dimerization of anthracene, the photoinduced patterns and the shape conformation could be erased and redeveloped for multiple times.

形状记忆：一种开发二维/三维弹性体潜在光图案形态的有效方法

这里应用形状记忆行为作为在改性聚（苯乙烯-嵌段-丁二烯-嵌段-苯乙烯）（SBS）上开发二维/三维（2D/3D）潜在光图案形态的新方法。通过将蒽基团连接到 SBS 链上，在变形状态下冷冻的弹性体通过蒽的光二聚化进行光图案化。在热处理后，形状记忆过程可以有效地发展潜在的光图案诱导的 2D-2D 和 2D-​​3D 形状转变。由于蒽的可逆二聚化，光诱导图案和形状构象可以多次擦除和重建。
