onductive plastics are presently used in, or being developed industrially for antistatic substances for photographic film, shields for computer screen against electromagnetic radiation, and for “smart” windows (that can exclude sunlight on demand).

7.11.1 Conductive Plastics Consumption and Applications
Conductive plastics consumption in value (see Table 7.40, according to BBC Research, and Figure 7.31 “Conductive Polymers and ICP Consumption”) grows slightly faster than total plastics when ICPs grow three times faster. Really, conductive plastics are a little market and ICP an emerging but very promising one.
I haven’t seen them being used to build power sources, transmitter circuits, and antennas small enough to fit through a shot delivery needle.
