How
to prepare multifunctional surfaces with high nucleation density
and fast droplet removal during droplet condensation remains a challenge.
It is believed that a water droplet on a superhydrophobic surface
(SHS) in the Cassie state is inclined to convert to the Wenzel state
under high-pressure or high-humidity conditions, which results in
the pinning effect. Hence, it is necessary to form thermodynamically
stable lubricant-infused surfaces (LISs) to be applied in water condensation,
especially under extreme working conditions. In this work, CuO LISs
with two different morphologies (chrysanthemum-like and dandelion-like
structures) in the slippery state were prepared and the effect of
surface morphology on water harvesting behavior was investigated.
The results indicated that dandelion-like CuO consisting of nanoneedles
exhibited inferior water harvesting behavior compared to chrysanthemum-like
CuO consisting of nanolamellas due to worse lubricating oil loss.
Furthermore, the strong intermolecular forces between the perfluoropolyether
(PFPE) lubricating oil and perfluorodecanethiol (PFDT)-modified coating
resulted in a durable lubricating layer, which exhibited favorable
anti-icing, anticorrosion, and liquid repellency even under strong
acid and alkali conditions, high shear force rate up to 7000 rpm,
and long-time ultraviolet light irradiation for 12 h. This work paves
the path for efficient droplet nucleation and removal, which has potential
in water harvesting in arid regions and water condensation for power
generation.
