Special Issue Information

Dear Colleagues,

Industrial activities pose a major challenge to the management of water contaminated by organic and inorganic pollutants and microorganisms. However, various wastewater treatment technologies that provide effective solutions to this problem have emerged. Theoretical and experimental developments in the application of functional materials as coating materials (e.g., carbon nanotubes/composites, graphene, nanoparticles, carbon nanofibers/nanotubes and nanoporous materials, oxides, etc.) play a central role in the advancement of these technologies due to their highly tunable properties and functions. This renewed interest in new coatings and films has led to the exploration of experimental and modelling activities in wastewater treatment and the detection of pollutants by novel sensors and biosensors.

The aim of this Special Issue, entitled “Novel Application of Films and Coatings for Wastewater Treatment”, is to promote and publish recent studies on wastewater treatment and the detection of organic and inorganic pollutants. The scope of this Special Issue includes (but is not limited to) the following topics:

  • Processes for coating deposition and modification;
  • Coating materials produced by different processes;
  • The theoretical and computational modelling of surfaces and interfaces;
  • DFT and experimental research based on thin films with regard to advances in wastewater treatment and the detection of pollutants by new sensors and biosensors;
  • Coatings for high temperatures;
  • The fundamental and functional properties of surface and interfaces;
  • Novel smart coatings for wastewater treatment;
  • New biopolymers for sustainable films and coatings;
  • Surface modification of sensors for the detection of organic and inorganic pollutants.

Oily wastewater poses severe ecological and health threats, but conventional separation technologies have limitations like low efficiency or high energy consumption. Herein, two superwettable carbon fiber (CF)-based membranes were fabricated for efficient oil–water separation. Using CF (low cost, excellent mechanical stability) as the substrate, Cu-TiO2@CF (superhydrophilic/underwater superoleophobic, renewable) was prepared via a deep ultraviolet (DUV)-assisted sol–gel method, and OTMS/Cu-TiO2@CF (superhydrophobic/superoleophilic) was obtained by modifying Cu-TiO2@CF with octadecyltrimethoxysilane (OTMS) via hydrothermal synthesis. Characterization showed Cu-TiO2 coatings uniformly covered CF, with strong substrate bonding. Both membranes exhibited outstanding performance: Cu-TiO2@CF achieved water fluxes of up to 79,839.6 L·m−2·h−1 and >97.3% separation efficiency for four oil–water mixtures; OTMS/Cu-TiO2@CF had a maximum oil flux of 86,593.4 L·m−2·h−1 and >98.1% efficiency. Cu-TiO2@CF regenerated via 10 min UV irradiation (restoring underwater oil contact angle to 153°), while OTMS/Cu-TiO2@CF achieved recovery through the process of UV irradiation followed by OTMS re-modification. Both membranes maintained stable performance over 100 cycles, demonstrating considerable potential for engineering applications. Full article
