Titre |
Water as a fuel: the materials basis for passive plant movements |
|
Résumé |
Dead plant bodies such as seed capsules are able to generate movement by the cyclic absorption of water
from the environment. This is based on water uptake by a composite of cellulose nano-fibrils and a
polymer matrix in the plant cell wall. Depending on the detailed architecture of the cellulose fibrils, this
leads to the generation of stresses and to complex movements. The underlying physical processes provide
guidelines for the development of mobile materials architectures which might be useful for many
applications, including soft robotics. |
