Fabrication of a metal membrane on a perforated flexible poly(tetrafluoroethylene) (PTFE) substrate was developed by employing spark-generated palladium (Pd) aerosol activation and the subsequent electroless plating of Pd. After aerosol activation, Pd agglomerates of spark-generated primary particles (∼2.6 nm in diameter) with a face-centered-cubic structure were deposited uniformly on the PTFE substrate. Homogeneous Pd particles with an average size of 188 nm were tightly packed together to form a Pd membrane after Pd plating. The average plating rate of Pd during 30 min of plating at an activation intensity of 25 μg/cm 2 was 14.2 μg/cm 2·min.
