Special Issue Information

Dear Colleagues,

Surface properties are a fundamental property of a solid surface and a current hot topic considering the key role they play in addressing the problems related to energy, environment, resources, and health. The research on surface and interface engineering has an important influence on promoting the development of new materials and the progress of human society. Accordingly, we are assembling this new Special Issue of Coatings to encourage scientists to showcase their original research articles, short communications, and review papers. This Special Issue will not only emphasize the design and synthesis of novel coating concepts but also their characterization, modeling, and applications.

Specific topics of interest include but are not limited to:

  • Coatings for antifouling membrane
  • Coatings for high temperature
  • Surface and interface modification
  • Adsorption, adhesion, functionalization
  • Hydrophilicity/hydrophobicity surface
  • Fundamental and functional properties of surface and interfaces

We look forward to receiving your contributions.

Dr. Dalong Li

Biofouling poses a significant challenge to the marine industry, resulting from the undesirable accumulation of various living organisms, including microorganisms, plants, shellfish, and others, on different surfaces submerged in seawater. The primary approach to address this issue involves the application of antifouling coatings, often incorporating active agents whose environmental impact has raised considerable concerns. In this article, we compare the effects of two natural and environmentally friendly antimicrobial compounds, capsaicin (CP) and Cinnamomum cassia oil (CO), when incorporated into hybrid sol–gel coatings. We tested formulations containing 4% and 8% by weight of each biocide for coating nylon substrates through immersion. This process yielded colorless, uniform surfaces with minimal defects and strong adhesion. We evaluated the antibacterial properties of the pure organic biocides against five bacterial strains commonly found in Chilean microfouling. Both compounds exhibited similar behavior against Gram-positive bacteria, but CP showed 2–5 times greater efficacy than CO against Gram-negative strains. Subsequently, we selected a Gram-negative strain for antibacterial tests on sol–gel/biocide samples. The results indicated that coatings with CP incorporation outperformed those with CO, achieving an efficiency of 99.9%. Lastly, leaching tests demonstrated that coatings with lower biocide concentrations (4%) exhibited a steady and gradual release of organic molecules, with sol–gel/CP 4% emerging as the most promising microfouling barrier coating for marine applications.

The stir-frying process in Chinese cooking has produced serious emissions of oily particles, which are an important source of urban air pollution. In particular, the complex composition of fine particulate may pose a threat to human respiratory and immune systems. However, current filtration methods for oily particulate fumes have low filtration efficiency, high resistance, and high equipment costs. In polypropylene (PP) electret filters, efficiency rapidly decreases and pressure drop (wind resistance) sharply increases after the adsorption of oily particles, due to the oleophilic properties of the PP fibre. We addressed this issue of filter performance degradation by fabricating a sodium perfluorooctanoate (SPFO) oleophobic coating on polyvinylidene fluoride (PVDF) fibre membranes for oily particle filtration. The SPFO coating showed a promising oleophobic effect even at low concentrations, which suggests it has oleophobic properties for different oil types and can be modified for different substrates. This fabricated oleophobic coating is thermostable and the oleophobic effect is unaffected by temperatures from 0 to 100 °C. By modifying the SPFO coating on the PVDF membrane, a high filtration efficiency (89.43%) and low wind resistance (69 Pa) was achieved without oil adhesion, so the proposed coating can be applied in the filtration and purification of oily fine particles and offers a potential strategy for preventing atmospheric oil pollution.
