论文摘要
我们研究了由温度变化激活的列型聚合物网络组成的平面未弯曲色带的平面外弯曲。我们的理论是拉伸和弯曲能，它们竞争建立平衡。我们表明，当达到平衡时，这些能量成分遵守a \ emph {coopmentarity}关系：一个是最小值的最大值。此外，我们确定了一个\ emph {Bleaching}制度：对于激活参数的足够大值（可以测量参考和当前配置中聚合物组织中有序程度之间的不匹配），色带的变形本质上与其厚度无关。
We study the spontaneous out-of-plane bending of a planar untwisted ribbon composed of nematic polymer networks activated by a change in temperature. Our theory accounts for both stretching and bending energies, which compete to establish equilibrium. We show that when equilibrium is attained these energy components obey a \emph{complementarity} relation: one is maximum where the other is minimum. Moreover, we identify a \emph{bleaching} regime: for sufficiently large values of an activation parameter (which measures the mismatch between the degrees of order in polymer organization in the reference and current configurations), the ribbon's deformation is essentially independent of its thickness.
