The direct fluorination of Kevlar and polyacetylene film

Kevlar fibers are known for their high strength. We have fluorinated these fibers in an attempt to increase their working temperature. Analysis shows that we are able to fluorinate a substantial amount of the aromatic ring, but loss to mechanical and thermal stability accompanies this. In the past, doping of polyacetylene film has shown to increase its conductivity by several orders of magnitude. In our efforts, we are also able to increase the conductivity of these films through direct fluorination. Our highest conductivity increase is approximately one order of magnitude. The fluorinated films show no increased resistance to air oxidation.
