Abstract
The present invention generally relates to deformable polymer composites, and more particularly to, deformable polymer composites with controlled electrical performance during deformation through tailored strain-dependent conductive filler contact. According to embodiments, a deformable elastomeric conductive material includes: an elastomeric polymer matrix; and conductive filler material uniformly dispersed in the elastomeric polymer matrix sufficient to render the material electrically or thermally conductive. The conductive filler material comprises a plurality of substantially non-entangled particles having an aspect ratio sufficiently large to enable the particles to substantially remain in contact and/or in close proximity with adjacent particles so as to maintain conductive pathways in the material when the material is subjected to deformation up to and exceeding 10% strain.
