Special Issue Information

Dear Colleagues,

We would like to invite you to submit your work to this Special Issue on "Efficiency of Coatings Formed in Various Ways” in the journal Coatings. Coating is a versatile technique used to protect against corrosion and erosion and extend the life of a wide variety of materials and products. At the same time, the main goal of forming a thin coating on the surface of a material or product is to improve their quality and impart new important properties. The characteristics of the coated object are controlled primarily by the targeted selection of the chemical composition and structure of the material forming the coating. Therefore, some researchers underestimate the role of the coating formation method when planning and conducting research. However, it is the method of coating that determines its structure, design, morphology, thickness, uniformity, and many other significant characteristics. Currently, a variety of coating formation techniques are widely used, the most important of which are: dip-coating technique, chemical deposition/electrodeposition, layer by layer assembly, spray coating, spin coating technique, electrospray/electrospinning coating technique, chemical etching technique, lithographic patterning technique, and miscellaneous techniques. It is impossible to list all the known techniques. In addition, interesting new coating techniques are constantly being developed. Each of them has its own advantages and disadvantages, so far unknown to a wide audience.

The purpose of this Special Issue is to publish original research articles, critical reviews, and the views of leading researchers in both academia and industry on all aspects related to recent advances in the development of new coating methods, research on the relationship of methods and process parameters, formation of coatings with structure, morphology and basic characteristics of coatings on the surface of materials and products of various nature. Contributions to the development of new concepts and mechanisms for forming coatings are also welcome.

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

New ways of forming coatings;
Materials with coatings formed in various ways;
New methods for determining the characteristics of coatings;
Advanced industrial applications of coatings formed by new methods.

Improvement of Textile Materials Processing Techniques by Applying Aqueous Dispersions of Polymers

by Luidmila Petrova, Rodion Grishin, Anvar Zimnurov, Olga Kozlova, Olga Odintsova and Elena Sangeeva

Abstract

This paper presents the results of studies in the field of polymer materials application for fabric modification. The aim of the study is to identify the most effective technique of deposition of Russian-made formulations of an acryl and urethane nature with pigment compositions in the processes of functional fabric production. The authors analyze the efficiency of three processing solutions: the technology of uniform dyeing with pigments consisting of coating the fabric surface with a pigment–polymer composition, the technology of obtaining “camouflage” fabrics based on a conceptually new approach to creating the IR-remission effect on printed fabrics, and the technology of creating a stable retro-reflective effect on a fabric through the use of polymers produced in Russia. The paper also shows the conceptual differences in the pigment distribution mechanisms in the fiber or in the polymer matrix depending on the technique of fabric coating. The cheapest and safest technique for the environment is the squeegee method of pigment application, which provides fabrics with both oil- and water-repellent properties. An innovative technology has been developed based on the squeegee method for achieving the IR-remission effect on fabrics with “camouflage” patterns. A series of physico–chemical tests (spectrophotometry, electron microscopy), as well as assessment of the consumer properties of the obtained textile materials confirmed the efficiency of using aqueous dispersions of acrylic polymers made in Russia for producing competitive functional fabrics.

Wear-Resistant Hydrophobic Coatings from Low Molecular Weight Polytetrafluoroethylene Formed on a Polyester Fabric

by Natalia P. Prorokova, Tatyana Yu. Kumeeva and Igor V. Kholodkov

Abstract

The paper presents a comparative analysis of the surface structure and morphology of hydrophobic coatings formed on a polyester fabric from various types of low molecular weight tetrafluoroethylenes by a new method. The low molecular weight compounds used include: ultrafine polytetrafluoroethylene of the FORUM^® trademark prepared through thermo-gas-dynamic decomposition of industrial polytetrafluoroethylene waste, and tetrafluoroethylene telomers, synthesized by radiation-chemical initiation from fluoromonomers in acetone, butyl chloride and trimethylchlorosilane solutions. The formation of coatings consists in deposition of low molecular weight tetrafluoroethylenes from solutions in supercritical carbon dioxide and organic solvents. The contact angle and water absorption of the polyester fabric with coatings containing the specified water-repellents are determined. The resistance of the achieved effect to various types of wear—washing, dry cleaning and abrasionis evaluated. The hydrophobic properties of the fabric are found to be affected by the coating plasticity characterized by the stiffness coefficient. The importance of this indicator to targeted changes in fabric properties is proved. All the considered types of low molecular weight polytetrafluoroethylene (PTFE) are shown to be effective water-repellents for the polyester fabric. Full article

White Phosphate Coatings Obtained on Steel from Modified Cold Phosphating Solutions

Abstract

The article presents a method for obtaining white phosphate coatings on steel by cold method. The deposition of protective phosphate coatings was carried out from solutions based on the preparation “Majef”, consisting of manganese and iron phosphates. To obtain phosphate films of white color, it is proposed to introduce zinc and calcium nitrates into phosphating solutions at the rate of 25–30 g/L. The surface of phosphate coatings was studied using the SolverP47-PRO atomic force microscope images, and the average grain size was determined. The structural and phase composition of phosphate coatings was been studied using X-ray diffraction analysis. The protective properties of phosphate coatings were estimated by corrosion rate indicators calculated from corrosion diagrams. Fine-crystalline uniform coatings were obtained from modified phosphating solutions at room temperature on steel. The white color of phosphate coatings is due to the increased content of phosphophyllite, hopeite, and parascholzite in their structural and phase composition. By applying protective phosphate coatings of white color on a steel product, corrosion can be slowed down by 4–4.5 times. However, white phosphate coatings are inferior in protective properties to unpainted coatings. The index of change in the mass of samples with white phosphate coatings because of corrosion is 0.371–0.41 g/(m²·h), and with unpainted coatings is 0.128 g/(m²·h). Full article
