Electrically Conductive, Breathable, Hydrophobic Membrance

Disclosed is a material which allows pressure equalization and vapor migration in an environmentally sealed electronic equipment enclosure while maintaining radio frequency interference (RFI) shielding.

The material consists of a membrane 1 of Gore-tex (Trademark of W.L. Gore & Associates, Inc.) expanded polytetrafluoroethylene (PTFE) bonded to a substrate of electrically conductive fabric 2. The expanded PTFE repels liquid water yet allows air and water vapor to pass. The conductive fabric substrate provides mechanical support for the PTFE membrane and electrical continuity for RFI shielding.

In use, the material is installed over openings in the enclosure 3 and held in place by any means that precludes leakage and allows electrical continuity along the material periphery.
