Special Issue Information

Dear Colleagues,

There is an increasing interest in using polymer materials as coatings not only by industrial demand but also by academic sector.  Polymer materials have found use in nearly all fields of application mainly due to their protection purposes. The main research interest is to create novel functionalities of polymer materials by physical and chemical structuring at the micro and nanoscale. As protective materials are subjected to different stress-strain levels, wear and environments, therefore, the mechanical properties play a key performance indicator. Mechanical characteristics of polymeric materials and coatings are declared based on measurements and interpretations of the results of measurement of mechanical properties and in connection with sample preparation, test conditions and external deformation forces. However, different indicative values of these characteristics follow similar aspects. Currently, these are not only classical aspects of the functionality, efficiency and economy of coatings in their production and operation, especially aspects of quality and durability, but also modern aspects of safety and environment-friendliness of coatings in their various applications. Experimental concrete empirical relationships have their cognitive value, but for the effective solution of various technical problems, the initial creation of a general prediction model is required based on a theory that takes into account all relevant physical relationships, processes and phenomena. At the same time, within the framework of verification testing, this model has to confront the presented theoretical prediction with the reality of a wide range of measured data beyond the primary data used to construct this model. Scientific and research simulations, whether performed by analytical or statistical methods, replace the investigated system with a simulation system, and information on the formation and use of the investigated coating can be obtained much more quickly and easily, i.e. without real experiments. However, the most common problem of declaring reliable simulation results is not disregarding the already verified general prediction model, but disregarding recommended input data intervals and input conditions, which may not always be entirely satisfactory or fully sufficient on the part of the user. In these cases, the only solution is to make the validity of the model more accurate or extend it. Neural networks are demanded and used with a great interest for tasks of classification, approximation and prediction. The preceding will require the derivation of new computational methods and procedures specified for the physicomechanical as well as thermodynamic and chemical problems of coating polymeric functional substrates. A comprehensive theory of the mechanism of interaction between coating and substrate materials should be elaborated in advance, while respecting the topographic parameters of the surfaces to be coated. High adhesion parameters, high abrasion resistance and good mechanical equilibrium of both components should be achieved at different operating stresses in the user conditions. The mechanical quality of the coating interconnection should ensure a flexible balance in strength and elasticity parameters. These are research topics, which are suitable for the creation of physicomathematical algorithms for quickly implementable machine calculations usable in design, research and practice.

In this work, we evaluated the influence of phosphoric acid in conjunction with a tannic converter formula on the adhesion of the coating system by employing the epoxy coating as the top coating. The morphology and the composition of the rusted steel before and after treatment were determined by scanning electron microscopy (SEM) and Fourier transform infrared (FTIR) spectroscopy. The adhesion test result showed that the adhesion strength between the rust and the epoxy coating was enhanced from 1.93 MPa to 11.63 MPa with the treatment by 50 g/L phosphoric acid in conjunction with a tannic converter formula. Further investigation of the working mechanism of such treatment revealed that the adhesion improvement could be attributed to the formation of a micro-cracked and compact conversion layer. This layer could reinforce the anchoring of epoxy coating through the pinning effect. It was also found that both the pH and the phosphate radical were the important factors to improve the adhesion strength. Full article

The performance of a skid resistance fog seal is studied to develop a high bond performance road skid resistance fog seal. Accordingly, a fog seal is developed based on the bond strength, permeability, and aging resistance. To develop the skid resistance fog seal herein, the skid resistance particle types and dosages are optimized according to the skid and wear resistance properties. The fog seal performance is then verified. Furthermore, the road performance of the skid resistance fog seal is studied, and the optimal amount of the skid resistance fog seal is proposed. Finally, the influence of the construction process on the skid and wear resistance is investigated. The results show that the self-made skid resistance fog seal has better bond strength, permeability, and aging resistance. The 0.6 kg/m2 skid resistance fog seal exhibits the best skid and wear resistance and water penetration performance, while the skid resistance fog seal constructed by the premix process has the best skid and wear resistance properties.

Modern means of transport increasingly utilize sandwich constructions. Among other things, the reasons for such state of affairs include the reduced weight of means of transport, and through this, better fuel economy as well as price. This work is dedicated to a systematic experimental study of the influence of various materials and sandwich designs on their mechanical properties. In the framework of experiments, sandwich-structured composites were exposed to two types of stressing: static as well as impact stressing. The testing of prepared samples was performed according to ASTM C-393 Standard, dealing specifically with the bending behavior of sandwich composite constructions and impact testing under the scope of ISO 6603-2 Standard test. In this article we deal with static and impact testing of the eight types of core materials, two types of coatings, two types of surface finishes, and two types of resins with a special emphasis on their use in constructions of some exterior or interior components of transport means.
