Hierarchical nanoparticle-in-micropore architecture for enhancement of mechanosensitivity and stretchability in mechanochromic electronic skins |
| 초록 |
Mechanochromic polymers that undergo color changes in response to mechanical stress can be used to directly visualize the stress distribution and mechanochemical activations, providing the promising applications in strain sensors and visualized e-skins. However, most previous mechanochromic polymers exhibit mechanophore activation after irreversible plastic deformation or provide reversible stretchability at the expense of mechanosensitivity. Here, we report a hierarchical nanoparticle-in-micropore architecture in mechanochromic polymers to enhance simultaneously the mechanosensitivity and stretchability of mechanochromic e-skins. The hierarchical structure results in stress concentration-induced mechanochemical activation of mechanophores, significantly improving the mechanochromic sensitivity to both tensile strain and normal force. This architecture enables a dual-mode mechanochromic e-skin for detecting static/dynamic forces via mechanochromism and triboelectricity. |
