“…Optimized biological solutions provide a source of inspiration for scientists to design rationally and to construct reproducibly multiscale structures for multifunctional integration. [4][5][6][7][8] In nature, nacre, glass sponges, teeth, bones, and other biomaterials have evolved different solutions to overcome the brittleness of their building materials. [9][10][11] Among the variety of biological materials, nacre is one of most promising owing to its superior mechanical strength and toughness (Fig.…”

Multifunctional integration is an inherent characteristic for biological materials with multiscale structures. Learning from nature is an effective approach for scientists and engineers to construct multifunctional materials. In nature, mollusks (abalone), mussels, and the lotus have evolved different and optimized solutions to survive. Here, bio-inspired multifunctional graphene composite paper was fabricated in situ through the fusion of the different biological solutions from nacre (brick-and-mortar structure), mussel adhesive protein (adhesive property and reducing character), and the lotus leaf (self-cleaning effect). Owing to the special properties (self-polymerization, reduction, and adhesion), dopamine could be simultaneously used as a reducing agent for graphene oxide and as an adhesive, similar to the mortar in nacre, to crosslink the adjacent graphene. The resultant nacre-like graphene paper exhibited stable superhydrophobicity, self-cleaning, anticorrosion, and remarkable mechanical properties underwater.

“…Therefore, polymer ligands containing thiol or fluorine functional groups of energy lower than water surface energy and higher than oils surface energy been enormously used to modified materials surface wettability and achieve surface superhydrophobicity and superoleophilicity [10][11][12]. Generally, surfaces with extreme wetting properties, such as superhydrophobic, superhydrophilic, superoleophobic, and superoleophilic surface have been found wide research interests due to their promising applications [13][14][15][16].…”

ABSTRACT:In this research, special wettable copper mesh owing superhydrophobicity and superoleophilicity property is reported using a low-cost, eco-friendly, rapid, and scalable synthesis methods. Hot water treatment (HWT) method is used to integrate the micro-textured copper mesh surface with a nanoscale roughness to achieve hierarchical micro-nano structured surface. The surface energy of the nanoscale In addition, the effect of the mesh's geometry on the wetting property was examined through correlations between wire diameter, pore size, and optimal values for the highest water CA.

“…[1][2][3] Traditionally, rough metallic oxide surfaces tend to be highly hydrophilic because of the strong affinity for hydroxylation at their surfaces. To obtain a hydrophobic surface of metal or metal oxide, surface coatings are usually needed to lower their surface free energy.…”

The wettability of metal oxides is vital to many applications including water erosion, filtration, and bioimplantation. In this work, the authors studied the wettability conversion behavior of picosecond laser structured copper surfaces in different atmospheres. The copper surfaces showed hydrophilicity initially after being irradiated by a picosecond laser. However, when they were stored in ambient air, their contact angles increased over time and became highly hydrophobic finally. The storage atmosphere influenced this process greatly, the atmosphere rich in CO2 or O2 would restrain the wettability transition, but the organic-rich and vacuum atmosphere would accelerate it. Detailed surface chemical analysis revealed that the adsorption of organic matters from the air played an important role in this wettability conversion process.
