Thin films doped with silver

The relationships between the intensity of the electric current and voltages (/—V) were measured for PPCN and PTDCN thin films doped with silver. It was found...

The immobilisation of antibacterial coatings onto conductive materials such as stainless steel or carbon fibre used in orthopaedic implants was investigated by two methods. The formation of thin films by electrodeposition of polypyrrole doped with polyanions able to complex silver ions, and their characterisation by SEM, FTIR and microbiological testing is described. The alternative method, involving chemical grafting of a thin film of a quatemaiy ammonium polymer using a surface initiator, is also discussed. 2 refs. 

Within the following sections we will discuss fundamental aspects of nanoparticle processing including the most important steps of characterization, particle formation, stabilization and post processing to end up with some general conclusions for a future process design. As model materials we use technically relevant semiconductor nanoparticles, so-called quantum dots (QDs) with direct band gap (ZnO, manganese doped ZnS and PbS(e)) and silver nanowires which have been proven to be excellent transparent electrodes for thin film solar cells [27].

Transparent conductive coatings combine high optical transmission with good electrical conductivity. The existence of both properties in the same material is, from the physics point of view, not trivial and is only possible with certain semi-conductors like indium oxide, tin oxide, cadmium oxide, and with thin gold and silver films, e.g. [157]. Particularly antimony or fluorine doped tin oxide (ATO, FTO), tin doped indium oxide (ITO), and aluminium, indium, or boron doped zinc oxide (AZO, IZO, BZO) are of technical importance [157a].
