摘要

Materials that can remain electrically conducting under large elastic stretching and bending are needed for fabrication of flexible displays, stretchable electronic implants, artificial mechanoreceptors, electrically actuated elastomers for artificial muscles, and loudspeakers. One approach to fabricate stretchable or elastic conductors has been to imprint patches of inorganic thin films with conductive interconnects on a prestrained elastomeric substrate. However, the performance and diversity of such elastic conductors are limited by the degree of initial prestrain, the brittleness of the inorganic films, and the compatibility between the inorganic materials and polymeric substrates. Another approach developed in recent years is to embed networks of conductive nanoparticles such as graphene or carbon nanotubes (CNTs), primarily by direct dispersion using sonication or high shear mixing, into an elastomeric polymer matrix.
