Polyaniline (PAni), an inherently conducting polymer, was synthesized with different intrinsic oxidation states from emeraldine salt (ES) and emeraldine base (EB) to leucoemeraldine base (LM). Free-standing membranes and thin film bi-layers of metal polyaniline were fabricated by magnetron sputter deposition of aluminum, copper, titanium and iron onto the polyaniline films. Metal-polyaniline samples were analyzed by scanning electron microscopy (SEM) and transmission electron microscopy (TEM) to investigate the microstructures of specimens. Auger electron spectroscopy (AES) and X-ray photoelectron spectroscopy (XPS) were employed to study the chemical bonding and interactions between deposited metals and polyaniline at the interfaces. Acoustic transmission properties of metal-polyaniline membranes were characterized by measuring the insertion loss as a function of acoustic frequencies and membrane geometry in various testing environments. Results indicated that the type of metal and the intrinsic oxidation state of the polyaniline influenced the structures and chemistry of the metal-polyaniline interfaces and membranes. Distinct interaction between metals and polyaniline in emeraldine salt form was observed, however, there was no evidence of direct interactions of the metals with emeraldine base and leucoemeraldine base polyaniline. Acoustic measurements of metal-polyaniline membranes demonstrated that the physical properties and geometry of the samples affected acoustic transmission between 100 Hz and 8,000 Hz.
