Dynamics of polyaniline deposition and solvation as a function of electrochemical control function
We propose specular NR measurements on polyaniline films during their deposition by different electrochemical control functions (potentiostatic, potentiodynamic and galvanostatic) known to generate films of different characteristics and, in devices, different performance. These will combine steady-state measurements of the films at intermediate states of deposition and dynamic experiments performed at the limits of time resolution of the FIGARO reflectometer. Issues addressed are variations in solvent population and spatial distributions of polymer and solvent within the growing films as functions of electrochemical control function and parameters. These outcomes relate directly to film uniformity, mechanical and electronic integrity, and internal transport processes that govern device switching times.
