Self-organizing structure in platinum films on a Nafion type polymer membrane

The morphology of platinum films deposited onto a polymer membrane material of the Nafion type has been studied. The films with thicknesses above $\sim$20 nm exhibit a specific structure (morphology) that is related to the process of self-organization. The observed phenomenon is interpreted and it is established that the main mechanism responsible for the self-organization is related to the dipole interaction between clusters of the deposited catalytic metal.
