4. Flexible Conductors and Percolation
Figure 12.2
When conducting particles or fibers are mixed into an insulating elastomer, a hole in the material-property space is filled. Carbon-filled butyl rubbers lie in this part of the space.

6. Figure 12.3
Two alternative configurations of copper and polyethylene, shown here in two dimensions but easily generalized to three. The one on the left has high electrical conductivity but low thermal conductivity; the one on the right has the opposite.

7. Figure 12.4
Two alternative hybrid configurations of copper and polyethylene give very different combinations of thermal and electrical conductivity, and create new “materials” with properties that are not found in homogenous materials.
