| Abstract Scope |
The creatures in nature possess unique smart material systems that can sense the environment change with evolved self-responsible architectures. For example, Japetella heathi octopus exhibits a remarkable ability to switch between transparency and pigmentation to evade the attention of predators. Here, we present a new approach to produce Japetalla heathi inspired smart material with self-responsible architectures by thermal field-assisted 3D printing. The levels of orientational and positional orders of liquid crystal in unique phases are modulated by the thermal field during the 3D printing. As a result, the 3D-printed material possesses a unique optical property that it can reversibly transit from transparent to opaque in response to external stimuli. The developed thermal field-assisted 3D printing provides a versatile manufacturing tool that enables the design and fabrication of bioinspired smart materials with complex 3D shapes for various potential applications, such as soft robots, flexible sensors, and smart anti-counterfeiting devices. |
