Preparation and characterization of hydrophobic aluminum surfaces: a study of the behaviour at low-temperature conditions

Preparazione di superfici idrofobiche e studio delle proprietà ice-fobiche per applicazioni su rete elettrica.

Over-head power lines are subjected to damages due to severe weather conditions and environmental pollutions. In particular, ice formation on conductors can lead to extensive mechanical damage such as conductors weighted down to the ground with consequent blackouts. The control of wettability properties of the high voltage and medium voltage aluminum conductors represents a strategy to avoid the formation of snow-sleeve and to lower the ice adhesion during a snowfall event.

In this work, several hydrophobic and super-hydrophobic surfaces were prepared on aluminum alloy by immersion of the specimens in boiling water followed by coating with a commercially available fluorinated siloxane. Their behaviour at low-temperature conditions was investigated in terms of water contact angle, icing delay and ice adhesion.
