科学领域:

材料科学材料科学材料科学
聚合物化学聚合物化学
软机器人软机器人软机器人软机器人

背景情况:

液晶弹性体 (LCE) 是软机器人和先进技术的有希望的软执行器材料.
同位体化温度 (T_i) 是关键的,它决定了执行温度和材料特性,从而影响应用.
传统的方法,如回火,对于LCE执行器不能永久调整T_i,因为T_i在过渡温度以上加热时会逆转.

研究的目的:

为了克服完全交叉连接的LCE中固定启动温度的限制.
开发一种方法来调整LCE的同位素化温度 (T_i),而不改变它们的基本化学结构.
为了能够从单一材料中创建具有可调节的执行温度的多功能软执行器.

主要方法:

利用了共价适应性网络,特别是具有动态共价键的液晶 (LC) 玻璃体.
在LC玻璃制剂网络中采用化来达到不同的T_i值.
利用动态共价键的可逆性来保持改变的T_i.

主要成果:

证明通过化实现的不同T_i值可以在LC玻璃制剂中永久保存.
展示了从相同交叉连接的LCE材料中获得各种具有不同的执行温度的软执行器的能力.
确认T_i的调节是可逆的,允许重新调整执行器的性能.

结论:

在LC玻璃体中,动态共价化学提供了一个新的途径来调整和保持LCEs的同位素化温度.
这种方法允许从单一材料制造可适应的软执行器,具有多个可调节的执行温度.
对T_i的可逆调显著扩大了LCE在软机器人和其他高科技领域的应用范围.
