PANI-PSS prepared from different aniline:PSS ratios were each deposited with PDADMAC. Each substrate was first coated with a 5 layers of PDADMAC/PSS which acted as a primer to insure good build up of the PDADMAC-PANI films. The pH of all the PANI-PSS solutions was adjusted to a value of 6. The LbL deposition method has been described previously and in our experiments, the dipping time was 5 min in each polyelectrolytes and three rinses in DI water of 3 min after each layer.
