针对深空、深地、深海和极地等极端环境科学探索前沿,利用智能构件的材料– 结构– 功能一体化增材制造技术,即4D 打印技术,以木材的多层网格状结构为生物模本,以聚乳酸为基体,聚己内酯为添加相,氧化石墨烯为光热转换剂,采用直写式3D 打印工艺成功制备了具有光响应形状记忆特性的仿生智能材料,研究了该智能材料的响应方式、变形过程、力学强度、变形温度等。结果表明,其能对光与温度刺激做出响应,实现自主形状回复,形变温度降低至55 ℃左右。在近红外光刺激下,形状固定率高达96%,形状回复率为93%,形状回复时间最快可达9 s。最后演示了在仿生可展开结构和光控释放包裹物结构中的应用,分别实现了按需光驱动展开和可控顺序释放功能,为航空航天可变形结构精准选择、远程控制和快速响应问题的解决提供了一种有效的仿生学新思路和新方法。
For the advanced scientific research in extreme environments such as deep space
deep sea
deep earth and polar
the material-structure-functional integrated additive manufacturing for fabricating intelligent components
that is
4D printing technology was used. The multilayer grid structure of wood was treated as bionic model. The polylactic acid
polycaprolactone
and graphene oxide were treated as the matrix
adding phase and light conversion agents. The bionic smart material with light-responsive shape memory properties was prepared via 3D printing technology of direct writing. The response mode
deformation process
mechanical strength
and deformation temperature of the smart material were researched. The results show that the bionic smart material can return to its original shape in response to light or temperature. The temperature of deformation is lowered to around 55 ℃. Under the near-infrared light response
shape fixed rate is as high as 96%
shape recovery rate is 93%
and the fastest shape recovery time is 9 s. Finally
the application to the bionic deployable structure and the optical response cladding release device were demonstrated
which can achieve light-driven deployment on demand and controlled sequential release functions. It provided an effective bionic new thought and method for solving the problems of accurate selection
remote control
and rapid response in aerospace deformable structures.
