Correlation between surface chemical composition and vapor sensing properties of gold-fluorocarbon nanocomposites

Chemical and morphological characterization of gold-fluoropolymer (CFx(Au)) nanocomposites, deposited by ion beam co-sputtering, has been carried out in order to establish a correlation between the morphological/chemical structure of the thin film and its performance as vapor sensor. Results derived from the analytical characterization allow to reach a deeper understanding of the swelling phenomena involved in the sensing processes.
