Chitin of poriferan origin and the bioelectrometallurgy of copper/copper oxide
Abstract
Chitinous scaffolds isolated from marine demosponge Ianthella basta represent novel templates for deposition of metals such as copper and copper oxides. In contrast to traditional Extreme Biomimetics methods which are based on high temperature reactions, here, we propose an alternative way based on a well-known process - electrochemical deposition or plating. This method allows production of 3D composite materials with metallic and metal oxide structures within their surfaces. For the first time chitinous scaffolds of poriferan origin, which possess a 3D network structure, were used for the copper plating. The nanocrystallites of metallic phase obtained on chitinous fibres represents replicas of the original nanofibrous substrate.
