Ultrathin organic coatings on copper, copper alloys and stainless steel for controlling the microbiologically influenced corrosion

Organic coatings only a few nanometres thick have been prepared on surfaces of pure copper, copper alloys and stainless steel samples by selfassembly, Langmuir-Blodgett technique and dip-coating. The resulted thin films have been characterized by dynamic contact angle measurements as well as by infrared techniques. The stability of the layers in aqueous environment and their protective effect against corrosion in NaCl solution and against bacterial adhesion was investigated.
