Abstract
A novel method for grafting polymers to polytetrafluoroethylene (PTFE) and composites grafted according to this method are described. PTFE at a surface of a substrate is reduced to polyacetylene (PA) and then doped with a suitable dopant. The doped PA/PTFE substrate is then contacted with a polymerizable monomer precursor capable of polymerizing with doped PA, to form the polymer of said precursor chemically bonded to the surface of the PA/PTFE substrate. A grafted composite with layers of varying thickness may be formed by further contacting the substrate bonded to polymer with preformed polymer of a similar cohesive energy density.
