ABSTRACT:
An electrically conductive web for safely and quickly discharging static electricity accumulated on personnel is disclosed. The web comprises a semi-conductive polymeric surface layer, which is in electrical contact with a conductive foraminous layer. The relative conductivity of these layers result in desirable electrical discharge characteristics. The composite structure may be bonded to a suitable supporting substrate and suitable electrical connection between the conductive foraminous layer is made with an electrical ground. Charged personnel coming into contact with the semi-conductive surface layer have their static charge quickly and safely discharged to ground potential.
