Special Issue Information

Dear Colleagues,

In organic materials usually serve as important components in thin films and coatings, and their morphologies or structure can bring excellent properties to the further specific applications in anticorrosion, catalysis, energy conversion or storage and so on. Moreover, the surface modification of inorganic materials can also influence their surface active sites or dispersion situation in the substrates, such as by chemical modification or plasma treatment. In this special issue “Recent progress of inorganic materials in thin film and coatings for functional application” of “Coatings”, the structure design of inorganic materials, which are used in thin film or coatings form,  will be focused, and their morphologies or surface adjustments will be emphasized.

This scope of this Special Issue will include, but is not limited to, the following fundamental and applied research topics:

  • Morphology control of inorganic materials and their application as thin film or coatings
  • Surface modification of inorganic materials and their application as thin film or coatings
  • Active sites control of inorganic materials (in thin film or coatings form rather than powder) for catalytic application
  • Composites with inorganic materials for anticorrosion application
  • The stabilization of inorganic and organic pigment
  • Preparation and application of superhydrophobic coatings

PDMS-based aerogel layers were synthesized as insulation layers by adopting mullite fiber (MF), hollow glass microspheres (HGM) and silica aerogel (SA) as the main fillers, and their loading amounts and content ratios were checked to investigate their effects on the thermal insulation properties in PDMS composites by thermal conductivity, thermal stability, and thermal insulation. The loading amount of nanofillers can significantly influence the insulation-layer performance, and the best performance with the lowest thermal conductivity of 0.0568 W/(m·K) was obtained by 10 wt% loading in PDMS with MF:SA:HGM = 2:2:1, which can achieve a temperature difference (∆T) of 67 °C on a 200 °C hotplate. Moreover, the variation of the filler content ratios can also affect the thermal insulation behavior when the loading amount is fixed at 10 wt%, and the best thermal barrier performance can be found for the sample with more SA as the filler (MF:SA:HGM = 1:3:1). The formed sample had the best thermal stability and thermal insulation property, which can stand a 9 min flame test without burning by butane spray gun, and the backside of the sample showed ∆T > 500 °C for the whole test.

The post-oxidation treatment (POT) is an important step in the preparation of silicon carbide (SiC) ceramic membranes via recrystallization sintering, which is generally considered to remove any possible free carbon. It is found, however, that increasing the temperature of POT improves not only the hydrophilicity and flux of SiC ceramic membranes but also their mechanical properties, chemical stability, etc. Therefore, it is necessary to study the principle of POT in order to obtain SiC ceramic membranes with optimal properties. In this study, the principle of POT was characterized via scanning electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, synchronous thermal analysis, and metallographic microscopy. According to the principle, the conditions, such as the temperature and air flow rate, of the post-oxidation process were optimized. Under the optimized conditions, POT improved the flux of SiC ceramic membranes from 1074 to 5118 L·m−2·h−1·bar−1, increased the bending strength from 26 to 35 MPa, and provided SiC ceramic membranes with high stability under acid and alkali conditions.
