Transparent, fluorine-free, heat-resistant, water repellent coating by infusing slippery silicone oil on polysiloxane nanofilament layers prepared by gas phase reaction of n-propyltrichlorosilane and methyltrichlorosilane

The subject of slippery liquid-infused porous surfaces have attracted many researchers due to their excellent liquid repellent properties and widespread usage in many fields such as anti-wetting, anti-icing, omniphobic, self-cleaning and anti-biofouling surfaces

Scholarcy highlights

  • The subject of slippery liquid-infused porous surfaces have attracted many researchers due to their excellent liquid repellent properties and widespread usage in many fields such as anti-wetting, anti-icing, omniphobic, self-cleaning and anti-biofouling surfaces
  • Polysiloxane nanofilaments were prepared on activated glass slides by an easy, clean and environmentally friendly gas phase reactions of n-propyltrichlorosilane for the first time and methyltrichlorosilane and the results were compared
  • Advancing contact angles of the n-PTCS based polysiloxane nanofilament layers were between 143 and 172° and contact angle hysteresis as low as 7° was obtained on these surfaces by altering the relative humidity and reaction time during filament growth
  • Transparent SLIPS were obtained by infusing silicone oil into polysiloxane filament layers of MTCS and n-PTCS
  • The obtained slippery liquid-infused porous surfaces shows excellent liquid repellency, very low contact angle hysteresis for long durations and maintains its water repellency after heating up to 80 °C for 6 days and after exposure to continuous water droplet flow up to 2 h
