| Description |
Understanding and tuning the wettability of the surfaces are highly intriguing for various
applications. The development of stable and transparent coatings over aluminium alloys
and glass substrates for making them superhydrophobic and extended oleophobic (lower
to the surface tension of 33.4 mN/m (coconut oil)) using a scalable and simple spray painting
technique is demonstrated. Fluorinated graphene oxide (FGO, fluorine content of 34.4 atomic
weight %), an atomically layered material, modified Polydimethylsiloxane (PDMS) polymer
composite is used as the paint for the coatings. The coated filmswere studied for their surface
and compositional features. A water contact angle (CA) of 173.7 degree (close to the highest ever
reported water CA, 175degree) is achieved with 60 wt% FGO in PDMS, and the same showing a CA
of 94.9degree with coconut oil, in conjunction with a low contact angle hysteresis (4degree). The work
of adhesion with the amount of FGO is studied and the surface energy of FGO containing
paints is calculated and compared with the bare paints using Zisman plot analysis
