The use of different drying procedures which can result in a mixed morphology film containing both amorphous and crystalline regions (spherulites) has been investigated. The EXAFS results show that each cobalt (on average) is associated with 4 oxygens and 3 bromines for all concentrations and drying regimes. The Co-O distance was found to be similar for most of the samples at similar to 2.110 Angstrom but this distance reduces slightly for the more dilute samples, indicating a possible greater interaction between the polymer chains and the cations. The Co-Br distance remains constant at similar to 2.380 Angstrom for all drying regimes and concentrations.
