Special Issue Information

Dear Colleagues,

We would like to invite you to submit your work to a Special Issue on "Preparations and Applications of Superwetting Polymeric Composites ". The performance of a polymer material is often dictated by its surface properties, such as its wettability. The wettability of a surface is determined by a combination of its chemical properties and topographical microstructures. Over the past 15 years, bioinspired polymeric composites possessing superwetting properties (superhydrophobicity, superhydrophilicity, superoleophobicity, and superoleophilicity) have attracted a large amount of commercial and academic attention due to their wide range of applications, such as waterproofing, anti-fogging, antifouling, anti-icing, fluidic drag reduction, anti-corrosion, oil/water separation, and functional textiles. Although superwetting polymeric composites are already used in a variety of products today, there is still a need to development new materials to improve their performance and enhance applications.

In particular, the topics of interest include, but are not limited to:

  • Superhydrophobic polymeric composites.
  • Superamphiphobic polymeric composites.
  • Polymeric composites with anisotropic or patterned wettabilities.
  • Polymeric composites with switchable wettability.
  • Superhydrophilic polymeric composites.
  • Slippery liquid-infused porous polymeric composites.
  • Functional textiles with superwetting properties.

Superhydrophobic materials have immense applications in the fields of industry and research. However, their durability is still a cause for concern. A facile method for preparing durable superhydrophobic films from carbon nanotubes (CNTs) and the main-chain type polybenzoxazine precursors is reported herein. We used probe ultrasonicator to prepare CNT/polybenzoxazine coatings. Compared with the general sonicating dispersion process, the dispersion time was greatly reduced from a few hours to 5 minutes and the prepared suspension exhibited film-forming characteristics well. The CNT/polybenzoxazine films, which do not contain any fluorinated compounds, exhibit remarkable durability against thermal treatment, organic solvents, corrosive liquids, and sandpaper abrasion, while retaining their superhydrophobicity. Furthermore, these CNT/polybenzoxazine films also showed durable superhydrophobicity after ultraviolet (UV) irradiation for 100 h. This CNT/polybenzoxazine film can be readily used for practical applications to make durable superhydrophobic coatings. Full article

Membrane-based metal substrates with special surface wettability have been applied widely for oil/water separation. In this work, a series of copper foams with superhydrophobicity and superoleophilicity were chemically etched using 10 mg mL−1 FeCl3/HCl solution with consequent ultrasonication, followed by the subsequent modification of four sulfhydryl compounds. A water contact angle of 158° and a sliding angle lower than 5° were achieved for the copper foam modified using 10 mM n-octadecanethiol solution in ethanol. In addition, the interaction mechanism was initially investigated, indicating the coordination between copper atoms with vacant orbital and sulfur atoms with lone pair electrons. In addition, the polymeric fibers were electrospun through the dissolution of polystyrene in a good solvent of chlorobenzene, and a nonsolvent of dimethyl sulfoxide. Oil absorption and collection over the water surface were carried out by the miniature boat made out of copper foam, a string bag of as-spun PS fibers with high oil absorption capacity, or the porous boat embedded with the as-spun fibers, respectively. The findings might provide a simple and practical combinational method for the solution of oil spill. Full article
