Special Issue Information

Dear Colleagues,

For centuries in material science, we have been striving to achieve full control over material design, to obtain products with specific chemical and physical properties. Nanotechnology in the modern world has become a "Philosopher’s Stone", which, out of common materials like silica, creates structures with incredible functionality in areas such as electronics, optics, and energy science. Surface functionalization by thin film deposition, among numerous other innovations, has created numerous applicational possibilities in fields such as corrosion protection, sensors, anti-reflection coatings, and catalysis to name a few. The Special Issue is dedicated to advances in thin-film technology, focusing on novelties in synthesis and structure properties and possible application areas.

I am pleased to invite you to submit manuscripts in the form of full research papers, short communications, or reviews. The “Functional Thin Films: Synthesis, Properties, and Applications” issue will present recent advances in organic, inorganic, or hybrid thin films. This section does not limit any thin film deposition techniques. All thin film studies, including those based on spin-coating, dip-coating, atomic layer deposition, chemical of physical vapor deposition, and other deposition techniques are welcome. The physical or chemical functionality of thin films remains the only key.

All manuscripts will undergo a rigorous peer review procedure and decisions will be based on the recommendations of independent reviewers.

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

  • Thin film deposition techniques;
  • Thin film structure;
  • Morphology of thin-film growth;
  • Self-assembly and self-organization in thin films;
  • Optical and electronic properties;
  • Anti-reflective coatings;
  • Corrosion protection;
  • Thin film sensors.

The surrounding environment often acts in a destructive way on materials we apply in our everyday life. The best way to protect them against such activity is to cover the basic materials with coatings possessing different properties, tailored to their applications. Anticorrosive layers are one of the biggest groups of such protective coatings, especially those containing silica or its derivatives. Depending on a type of silica precursor and a method of deposition, one can obtain coatings of different structures and properties. In this work, three different silica precursors were applied: TEOS (tetraethylorthosilane), DDS (dimethyldiethoxysilane) and AerosilTM (the powder silica). Sols of different concentrations of the aforementioned precursors as well as commercially available preparations (Sarsil H1 4/2 and SILOXAN W290) were applied for thin films deposition by a dip coating or an infiltration method. The substrates could be divided in two groups: metallic (steel and titanium or titanium alloys) and porous (represented by old brick, sandstone and limestone). Following the deposition process, the layers on metallic substrates were additionally annealed at 500 °C to improve their adhesion and mechanical properties, while those on porous materials were dried in air. All prepared coatings were primarily studied by FTIR spectroscopy and X-ray diffraction. The morphology of their surfaces was imaged by SEM and AFM microscopies, which also allowed determination of the roughness of obtained materials. The measurements of wetting angle values enabled to find the relationship between the surface topography, the type of silica precursor and the hydrophobic/hydrophilic properties of the samples. The results confirmed the hydrophobic properties of coatings obtained by the infiltration technique on the porous materials and the high hydrophilicity of the annealed thin film deposited on the metallic substrates.

A predictive film thickness model based on an accepted equation of state is applied to the spin-coating of sub-micron poly(methylmethacrylate) viscous thin films from toluene. Concentration effects on density and dynamic viscosity of the spin-coating solution are closely examined. The film thickness model is calibrated with a system-specific film drying rate and was observed to scale with the square root of spin speed. Process mapping is used to generate a three-dimensional design space for the control of film thickness. Full article
