Abstract:

A process and the product made thereby are disclosed in the preferred form of this process wherein a polymeric packing material is first fluorinated at ambient temperature for an interval of contact with elemental fluorine. Then, contact with a strong base converts the polymer into conjugated double bonds, reducing electrical resistance. The double bonds yield a surface layer able to controllably conduct electrical current.
