Special Issue Information

Dear Colleagues,

Coatings and thin films materials have increasingly attracted the attention of scientists and technologists. Due to the unique microstructure, large surface-to-volume ratio, small size, and substrate constraints of thin films and coatings, their mechanical properties differ from those of bulk materials. Understanding the processes that control the mechanical properties of thin films and coatings structures is important in a variety of scientific and technological applications, such as various preparation techniques and structural fracture failure analysis of hard coatings and films. There are many film-substrate structures in MEMS, and their mechanical behavior will be different in the micro-scale structure. Meanwhile, during application, many physical fields are included, such as electric, magnetic, moisture, and thermal fields. Therefore, this is also a multi-field and multi-scale analysis, which will make the problem more complicated.

In this Special Issue, modern trends of hard coating deposition and preparation and analysis of protective coatings, including the correlation of coatings structure and microstructure with their mechanical properties, are highlighted and discussed. We cordially invite you to submit a manuscript for this Special Issue. Full papers, communications, and reviews are all welcome.

Research areas may include (but are not limited to) the following:

  • preparation of coatings and thin films;
  • structure and microstructure analysis of coatings and thin films;
  • fracture failure analysis of coatings and thin films;
  • simulation and theoretical analysis of coatings and thin film failure;
  • application of protective coating.

We look forward to receiving your contributions!

The mechanical response of a quasicrystal thin film is strongly affected by an adhesive layer along the interface. In this paper, a theoretical model is proposed to study a thin two-dimensional hexagonal quasicrystal film attached to a half-plane substrate with an adhesive layer, which undergoes a thermally induced deformation. A perfect non-slipping contact condition is assumed at the interface by adopting the membrane assumption. An analytical solution to the problem is obtained by constructing governing integral–differential equations for both single and multiple films in terms of interfacial shear stresses that are reduced to a linear algebraic system via the series expansion of Chebyshev polynomials. The solution is compared to that without adhesive layers, and the effects of the aspect ratio of films, material mismatch, and the adhesive layer, as well as the interaction between films, are discussed in detail. It is found that the adhesive layer can soften the localized stress concentration. This study is instructive to the accurate safety assessment and functional design of a quasicrystal film system.

This study presents the development of photolithography employing biomass-based resist materials derived from polyglucuronic acid. Traditional resist materials require coating and developing procedures involving organic solvents, whereas our approach enables the use of water-based spin-coating and developing processes. The water-soluble biomass resist material, derived from polyglucuronic acid, exhibited exceptional photosensitivity at an exposure wavelength of 365 nm and a dose of approximately 90 mJ/cm2. We successfully patterned the microstructures, creating 3 µm lines and 6 µm holes. This organic solvent-free coating process underscores its applicability in scenarios such as in the microfabrication on plastic substrates with limited organic solvent tolerance and surface-patterning biomaterials containing cells and culture components.
