- 摘要：
- Despite their potential in various fields such as soft robots, drug
delivery and biomedical engineering, magnetic hydrogels have
always been limited by their poor mechanical properties. Here a
universal soaking strategy has been presented to synthesize tough
magnetic nanocomposite (NC) hydrogels. We can simultaneously
solve two common issues for magnetic hydrogels: the poor
mechanical properties and poor distribution of magnetic particles.
The toughness of the magnetic NC hydrogel achieves approximately
11 000 J m2. The outstanding properties of tough magnetic
hydrogels will enable myriad applications. Here we demonstrate a
new application for remotely triggered shape morphing. Heterogeneous
structures based on magnetic hydrogels are shown to
evolve into bio-inspired three-dimensional (3D) shapes (lotus flowers)
from 2D-structured sheets. The self-folding of the structure is
controlled by the magnetothermal effect in an alternating magnetic
field. The capability to control the shape morphing of a multimaterial
system by a magnetic field may emerge as a new general
strategy for programming complex soft structures.
