Abstract:
Aim:
To Fabricate the superhydrophobic Stainless Steel (SS) mesh using Trimethylchlorosilane (TMCS) through a Chemical Vapor Deposition (CVD)
method for the oil-water mixture separation.
Background:
The frequent oil spills have a devastating impact on marine ecosystems and the environment. The porous materials with superhydrophobic
properties have been created to separate oil and water effectively. Due to their ability to effectively separate oil and water, superhydrophobic
coatings have gained significant attention.
Methods:
The cleaned stainless-steel mesh was put on a stand and covered with a glass container. Within the container, 50 mL of hexane, which contained 1
mL of TMCS, was added. The mesh was then left for 3 h to undergo the CVD process.
Results:
The silane content with low surface energy creates a highly rough structure on the mesh surface. The optimal mesh coating is superhydrophobic,
having a strong affinity to oil and a water contact angle of 162 ± 2°. The coated mesh has shown a separation efficiency of over 97.8% for different
oil-water mixtures. The coatings sustain their superhydrophobicity up to 30 tape peels and 40 times sandpaper abrasion, indicating good
mechanical durability.
Conclusion:
The study concludes that the S-3 sample is mechanically stable and can withstand various tests such as adhesive tape peeling, sandpaper abrasion,
bending, folding, and twisting. It efficiently separates oil and water mixtures on a large scale with high efficacy.
