变色龙启发新材料灵感
Human skin is soft and compliant, but it can quickly become stiff when deformed to prevent injury.
人类的皮肤柔软而顺滑,不过在需要防止伤害时却可以迅速变硬。
Chameleon skin can change color when the animal goes from a relaxed to an excited state.
变色龙从放松状态转为兴奋状态时,它的皮肤可以改变颜色。
Although these properties can be captured individually in synthetic materials, the combination of different dynamic responses can be hard to control.
尽管这些性质可以分别用不同的合成材料来模拟,不过几个不同的动态反应的组合就很难控制了。
Vatankhah-Varnosfaderani et al. created triblock copolymers of the ABA variety, where the A blocks have a linear structure and the B blocks are like bottlebrushes.
沃坦卡.瓦诺斯芬德瑞利等创建了一种ABA式的三嵌段聚合物,其中A区块拥有线性结构,而B区块就像杯刷一样。
When strained, these polymers stiffened like human skin and changed color, thus giving the materials a range of adaptive properties.
当收缩时,这种多聚物会想人的皮肤一样变硬同时改变颜色,因此使这种材料具有了广泛的适应性。
Active camouflage is widely recognized as a soft-tissue feature, and yet the ability to integrate adaptive coloration and tissuelike mechanical properties into synthetic materials remains elusive.
积极的伪装往往被人们认为是软组织的特征,不过将整体适应变色和组织样的机械性能整合到合成材料里还是很难完成的。
They provide a solution to this problem by uniting these functions in moldable elastomers through the self-assembly of linear-bottlebrush-linear triblock copolymers.
科学家们想到了一个解决问题的方法,就是通过将这些特性结合起来用可塑弹性体通过线性块-杯刷块-线性块自组装的方式形成三嵌段聚合体。
