Abstract
An expanded polytetrafluoroethylene substrate comprising a microporous microstructure, an interlayer over at least a portion of the microstructure, the interlayer containing a reactive functionality, and a functional layer attached to the interlayer, the interlayer comprising a sol-gel or a polyvinylalcohol. The functional layer of the substrate having functional sites with a density of at least 50 nanomoles/cm2.
