Mechanical durability of superhydrophobic and oleophobic copper meshes

Construction of mechanically durable superhydrophobic surfaces by thermal spray deposition and further surface modification

“…The mechanical durability of the superhydrophobic surfaces was evaluated by scratch testing, which has been used for measuring the mechanical abrasion resistance of superhydrophobic surfaces [30][31][32][33][34]. This approach could be appropriate for assessing the anti-abrasion performances of superhydrophobic surfaces, largely due to the fact that the surfaces are rarely used under severe wear conditions.…”

2D and 3D Bulk Materials for Environmental Remediation: Air Filtration and Oil/Water Separation

“…A chemical etching procedure is used to prepare superhydrophobic Cu meshes with rough structures because of simple and inexpensive methods. However, most Cu meshes with rough surfaces have been synthesized using toxic chemicals, including strong acids/bases and oxidants for synthesizing [ 161 , 184 , 185 ]. A convection heat treatment approach was proposed for replacing a previous method using toxic chemicals [ 163 ].…”

Facile fabrication of amphiphobic surfaces on copper substrates with a mixed modified solution

“…Nevertheless, most methods require special experimental conditions and equipment. For example, Yin et al 21 prepared superhydrophobic and oleophobic copper meshes by immersing samples into a mixed aqueous solution of NaOH and (NH 4 ) 2 S 2 O 8 for 30 min, modifying the etched copper in a 1H,1H,2H,2H-peruorooctyltrichlorosilane solution for 2 h, then setting the experimental conditions to 100 C for 1 h, and annealing the samples in an oven. Only through these complicated procedures and special experimental conditions, the low surface energy groups could be successfully assembled on the rough surfaces to reduce the surface energy.…”
