Special Issue Information

Dear Colleagues,

We would like to invite you to submit your work to this Special Issue of Coatings entitled “Coatings for Building Applications”.

The protection of buildings with smart coatings has long been a challenge for the coating industry, due to the impact of pollutants and synergism of climate parameters, intensively affecting the building façade. Into this framework, research activities were addressed and focused on self-cleaning, hydrophobic, and super-hydrophobic coatings, exhibiting durability to the environmental loading and compatibility to the building substrate. Recent advantages in nanoscience have resulted in the establishment of smart materials with multifunctional properties, such as self-cleaning, self-healing, antifungal, biocidal, super-hydrophobic, anti-graffiti, breathable paints, energy-efficient paints, renders with nano-additives, etc. Nanostructured coatings could accomplish more than one of the above-mentioned desired functionalities and therefore could be considered as powerful suggestions for building protection and a clean environment. In this Special Issue, contributions on the above topics will be welcomed, and authors are encouraged to submit their works concerning inorganic and organic coatings with specific properties addressing both building and environment protection.

The topics of interest include but are not limited to the following:

  • Photocatalytic and self-cleaning coatings;
  • Hydrophobic, super-hydrophobic, and water/oil repellent actions;
  • Coatings with biocidal and antifungal functions;
  • Anti-graffiti properties;
  • Energy-efficient paints;
  • Renders with nano-additives;
  • Coatings with CO2 sequestration action.

Radiative cooling is a passive cooling technology that can cool a space without any external energy by reflecting sunlight and radiating heat to the universe. Current reported radiative cooling techniques can present good outside test results, however, manufacturing an efficient radiative material which can be applied to the market for large-scale application is still a huge challenge. Here, an effective radiative cooling coating with a near-ideal selective emissive spectrum is prepared based on the molecular vibrations of SiOx, mica, rare earth silicate, and molybdate functional nanoparticles. The radiative cooling coating can theoretically cool 45 °C below the ambient temperature in the nighttime. Polyethylene terephthalate (PET) aluminized film was selected as the coating substrate for its flexibility, low cost, and extensive production. As opposed to the usual investigations that measure the substrate temperature, the radiative cooling coating was made into a cubic box to test its space cooling performance on a rooftop. Results showed that a temperature reduction of 4 ± 0.5 °C was obtained in the nighttime and 1 ± 0.2 °C was achieved in the daytime. Furthermore, the radiative cooling coating is resistant to weathering, fouling, and ultraviolet radiation, and is capable of self-cleaning due to its hydrophobicity. This practical coating may have a significant impact on global energy consumption. Full article

Title: Evaluation of the performance and durability of self-cleaning TiO2 treatments applied to cement-based renders

Abstract:

The application of photocatalytic coatings based on TiO2 nanoparticles to building materials has diffused over last decades, following the encouraging results obtained in many laboratory studies and in a number of in-the-field testing campaigns on the self-cleaning, antimicrobial and depolluting performances provided by these coatings. However, the results clearly point out the need of a deeper understanding of the effectiveness of TiO2-based treatments when applied over different substrates and their durability when exposed to outdoor environment.

The present paper investigates the behaviour of a nanodispersion of titania nanoparticles applied to cement-based substrates. Cementitious materials are widely used in building façades, roofs, structures, roads, and tunnels, hence any improvement in their performance and/or introduction of new and unique functionalities have potentially a very high impact on our everyday life. The TiO2 nanodispersion was applied with different techniques (brushing and spraying) on three cement-based substrates (a render, a prefabricated board and a painted prefabricated board), investigating its photocatalytic activity. Then, the samples were subjected to two artificially weathering procedures, involving rain washout and UV-light exposure, and the changes in terms of photocatalytic activity and contact angle were measured. The results suggest that the nature of the substrate plays a key role in the performance of the coating and that weathering as a significant role as well.
