Special Issue Information

Dear Colleagues,

The aerospace environment is known to be aggressive and hostile, and its effects on aircraft and spacecraft can be very detrimental.

Ice accretion on aerodynamically efficient surfaces such as wings and empennages is widely recognized as one of the most severe weather hazards for aircraft. Self-cleaning, superhydro- and ice-phobic nanocomposite films and coatings are technological solutions that show great promise in making aircraft safer and more efficient.

At high altitude, spacecraft surfaces are exposed to several degrading phenomena, such as oxygen atom attack, radiation exposure, electrostatic charge and hypervelocity impacts. It is therefore necessary to find and provide solutions to protect and properly isolate spacecraft components from the space environment. Multifunctional nanocomposite films and coatings can play a key role in protecting and safeguarding the various spacecraft components from the surrounding environment. These films and coatings have other potential uses, including in sensors, structural health monitoring and electromagnetic interference shielding. Furthermore, special solutions are needed to expand human space exploration and allow for the establishment of human bases on Mars and the Moon within our lifetime. However, these ambitions are constantly faced with the limits of current technologies. Nanotechnology has the ability to go beyond current technological challenges by enabling the engineering of novel films and coatings.

This Special Issue aims to highlight recent studies on nanocomposite films and coatings to improve aircraft efficiency and safety, protect the operative life of spacecraft and promote human space exploration.

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

  • Multifunctional films and coatings for aerospace applications;
  • Anti-icing and UV protective coatings for aircrafts;
  • Nanocomposite paints for aircraft and spacecraft;
  • Manufacturing of films and coatings for aerospace applications;
  • Protection in harsh space environment;
  • Degradation mechanisms in the atmosphere and in space environments;
  • Nanocomposite films and coatings for mitigation of space effects such as oxygen atom attack, contamination, solar UV degradation, physical sputtering, spacecraft glow, spacecraft charging, radiation effects and hypervelocity impact damage on spacecraft surfaces;
  • Sensing and structural health monitoring for aerospace applications;
  • Experimental testing and numerical analysis to determine performance of nanocomposite films and coatings in service;
  • Durability and reliability of films and coatings in operative aerospace environments.

To investigate ultraviolet (UV) radiation effects on tribological properties of Mo/MoS2-Pb-PbS film, ultraviolet (UV) radiation exposure tests were carried out for 20 h, 40 h, 60 h and 80 h by space UV radiation simulation device developed by our team, which [...] Read more.
To investigate ultraviolet (UV) radiation effects on tribological properties of Mo/MoS2-Pb-PbS film, ultraviolet (UV) radiation exposure tests were carried out for 20 h, 40 h, 60 h and 80 h by space UV radiation simulation device developed by our team, which can reach 3 UV radiation intensity. The exposure time in test was equivalent to the radiation of 100 h, 200 h, 300 h and 400 h in the space. Then, the vacuum friction test of Mo/MoS2-Pb-PbS thin film was performed under the 6 N load and 100 r/min, and friction test time of each sample was 20 min. By SEM, TEM, XPS the composition and morphology of Mo/MoS2-Pb-PbS film surface after UV radiation were analyzed. UV radiation could change the microstructure significantly and relative content of S element and MoS2 on the surface of the films decreased, and light mass loss of the films occurred. The tribological properties will also recover with the increase of sliding time, although the friction coefficient fluctuation of the film increased at the starting stage of the friction test. The damage of Mo/MoS2-Pb-PbS under UV irradiation was mainly caused by the volatilization of the enriched S element in the surface layer due to the high temperature heating of UV irradiation.
