This paper describes a new strategy for fabricating a gold ͑Au͒ island film based on a silver ͑Ag͒ aerosol surface activation onto
a porous polytetrafluoroethylene ͑PTFE͒ substrate, followed by electroless deposition ͑ELD͒. Spark produced Ag aerosol nano-
particles nm in diameter͒ were physically captured gAg/cm2 PTFE in activation intensity͒ onto the surface of the
substrate. After annealing ͑240°C͒ in nitrogen atmosphere, the activated substrate was placed into a solution for Au ELD ͑at
90°C͒. essive Au deposition introduced an island film having the thickness of m ͑the lateral dimensional and mass
growth rates of nm/min and gAu/cm2 PTFE-min, respectively͒, which was similar to the diameter of the island films
at 180 min of deposition. X-ray diffraction certified the uniformity of the films with the Au ͑111͒ crystallographic orientation as
the predominant one. The corresponding crystallite sizes
