HPP Conductive Polymers: Combining Performance and Conductivity

Combining Mechanical Performance and Electrical Conductivity

Traditionally insulating, certain high-performance polymers (HPPs) can be formulated to become electrically conductive. By adding active fillers (graphite, carbon fibers, nanotubes), they can be used to design lightweight, chemically resistant parts capable of conducting electricity, without the drawbacks of metals (weight, corrosion, oxidation).

How is a polymer made conductive?

Two main approaches:
- Incorporation of conductive fillers (carbon fibers, carbon black, graphite) → to achieve a percolation threshold
- Chemical doping (PANI, PPy) for modulated semiconductivity requirements
These processes transform an insulator into a conductive or dissipative material, while retaining the mechanical and thermal advantages of HPPs.
