摘要
Free-standing melanin films were successfully synthesised electrochemically from dopa. The Optimum synthetic conditions such as pH, concentration and current were determined, and it was found that free-standing film,.; could only be formed when ITO glass electrodes were used. The films were analysed by solid state NMR and XPS which showed the presence of indolic moieties characteristic of melanin-type macromolecules. The film showed higher conductivity than chemically synthesised melanin previously reported in literature and also exhibited photoconductivity. (c) 2005 Elsevier Ltd. All rights reserved.
