中文摘要：

nematic 弹性体和 nematic hydrogels 被知道显示有斑纹的模式。与为 nematic 弹性体的建议模型的大身体相对照，很少研究存在解释在 nematic hydrogels 脱衣。在这篇论文，一个理论模型基于免费精力最小化被开发模仿在 nematic hydrogel 的层脱衣的干燥导致结合了到僵硬底层。液体在 nematic hydrogel 的水晶的聚合物由某些角度旋转形成响应弄干的环境脱衣。而且，脱衣发生仅仅因为湿度的一个有限范围，和这个范围的边界能被调节。

英文摘要：

Both nematic elastomers and nematic hydrogels are known to display striped patterns. In contrast to a large body of proposed models for nematic elastomers, few studies exist to interpret striping in nematic hydrogels. In this paper, a theoretical model based on free energy minimization is developed to simulate the drying-induced striping in a layer of nematic hydrogel bonded to a rigid substrate. The liquid crystalline polymers in the nematic hydrogel rotate by certain angles to form the striping in response to a drying environment. Moreover, the striping occurs only for a finite range of humidity, and the boundaries of this range can be tuned.
