摘要
Silicone rubber high voltage insulators are sometimes reported to be colonised by microorganisms. When the hydrophobic polymeric surface is covered by a hydrophilic biofilm, the isolating properties of the insulator are reduced. However, cleaning the surface can restore the function of the insulator. In this study biofilms colonising insulators from Tanzania, Sri Lanka and Sweden were investigated. Results showed that the examined biofilms shared several properties. Small unicellular green algae associated with bacteria and filamentous fungi dominated all samples. Environmental scanning electron microscopy (ESEM) with X-ray energy disperse spectroscopy (EDS) is proposed as a new method to determine if an infected surface can be cleaned. (C) 2004 Elsevier Ltd.
