Special Issue Information

Dear Colleagues,

Antibacterial coatings on surfaces or devices for medical or pharmaceutical use are developing very rapidly, and represent a major component of the overall strategy to mitigate bacterial pathogens. The aim is to prevent the proliferation of pathogenic bacteria and, at the same time, to eradicate the sources of human infection with bacterial pathogens that are becoming increasingly resistant to conventional antibiotic treatments. Thanks to advances in fields such as materials science, biotechnology and bioengineering and the growing research available in environmental microbiology, there are now more possibilities for designing surfaces or objects with antibacterial properties. We consider those materials that have the ability to release antibacterial substances in a controlled manner but are environmentally friendly, as well as materials with antibacterial coatings which retain this property in the medium and long term.

We are pleased to invite you to contribute to the discoveries in this field by publishing in this Special Issue of Coatings articles which highlight the scientific and theoretical research in this niche of material coatings.

Aims:

This Special Issue aims to publish original research papers aligned with the journal’s scope, in the field of the science and engineering of coatings, thin and thick films, surfaces and interfaces, but in this case designed materials must have antibacterial properties.

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

  • Material science of coatings (design and characterization of new materials used for coatings with antibacterial properties);
  • Mathematical modelling of realizing control kinetics;
  • Antibacterial-release-based coatings;
  • Active approaches: stimuli-responsive materials;
  • Mechanisms of bacteria-triggered approaches;
  • Multifunctional coatings with antibacterial properties;
  • Multi-release coatings with antibacterial properties;
  • Multi-approach coatings with antibacterial properties;
  • Multi-property (smart) coatings with antibacterial properties;
  • Long-term stability of antibacterial properties of coatings;
  • with antibacterial properties;
  • Antifouling coatings (with application in naval or food industries);
  • Other aspects regarding antibacterial coatings.

To obtain dual functions of antibacterial and self-healing of a coating, nano-silver solution microcapsules coated with urea formaldehyde resin were selected for antibacterial agents, and rosin-modified shellac microcapsules coated with melamine formaldehyde resin were selected for repairing agents. The optical, mechanical, antibacterial, self-healing, and other physicochemical properties of the coatings were analyzed. The method of adding two microcapsules independently did not affect the coating’s hardness. When the primer was prepared by self-healing microcapsules and the topcoats were prepared by antibacterial microcapsules, the hardness of the prepared coatings was maintained at 3 H, with the adhesion up to class 2, the impact strength up to 18 kg·cm, and the roughness as low as 1.144 µm. The elongation at fracture of the coatings prepared by adding microcapsules independently was improved by 2.2%. The self-healing microcapsules release the repair agents to improve the mechanical properties of the coatings. In terms of the antibacterial properties of the coatings, the method that involves adding the microcapsules independently is better than mixed adding. Against Escherichia coli, the antibacterial rate of coatings prepared by adding microcapsules independently reached 82%. Against Staphylococcus aureus, the antibacterial rate of coatings reached 83.3%. At the same time, the self-healing rate was up to 41.1%. The two microcapsules were added to the water-based coating independently to obtain antibacterial and self-healing functions with good comprehensive properties. By modifying coatings on the Andoung wood (Monopetalanthus spp.) with antibacterial microcapsules and self-healing microcapsules, it is possible to obtain good antibacterial properties, further protect the wood substrate, and broaden the application range of functional coatings.

In this paper, a chitosan-modified nano-silver solution was used as the core material of an antibacterial agent, and melamine formaldehyde resin was coated onto the core material to obtain the antibacterial microcapsules. The core/wall ratio, the stirring rate, the mass ratio of chitosan to silver ions, and the concentration of the emulsifier were used to carry out four-factor and three-level orthogonal experiments to explore the most significant factors affecting the coverage rate and output of microcapsules and the best preparation technology. The results showed that the concentration of the emulsifier was the most important factor affecting the preparation of microcapsules. The higher the concentration of the emulsifier, the better the dispersed morphology of microcapsules, and the higher the coverage rate, up to 44.0%. The antibacterial coating was prepared by mixing microcapsules with a waterborne primer at a content of 4.0%. Its optical properties, mechanical properties, and antibacterial properties were analyzed. By increasing the concentration of the emulsifier, the gloss of the coating showed a trend of first increasing and then decreasing. When the emulsifier concentration was 2.0%, the gloss of the Andoung wood surface coating reached the maximum value of 21.23%. The influence of emulsifier concentration on the color difference of coating had no obvious law, and it was negatively related to the light transmittance. In terms of mechanical properties, the concentration of the emulsifier is directly proportional to the hardness and impact resistance of the coating, with the maximum reaching 31 kg·cm, and is negatively related to adhesion and roughness. In terms of antibacterial properties, the higher the concentration of the emulsifier, the better the antibacterial properties of the coating. When the concentration of the emulsifier was 4.0%, the antibacterial rates of coating which coated the glass substrate were 71.3% and 80.0% for Escherichia coli and Staphylococcus aureus, respectively. The antibacterial rates of the Andoung wood surface coating reached the maximum, which were 68.4% and 73.2%, respectively, and the antibacterial performance was excellent. In this study, an efficient antibacterial microcapsule for waterborne coatings was prepared, which provided the reference value for the application of antibacterial microcapsules in waterborne coatings.

Using microencapsulation technology and the natural antimicrobial properties of aloe-emodin, the antimicrobial microcapsules were prepared by in situ polymerization using urea-formaldehyde resin as the wall material and aloe-emodin as the core material. The antimicrobial microcapsules were mixed into waterborne coatings to improve the antimicrobial ability of waterborne paint films against bacteria for better protection of substrates. The purpose of this study was to optimize the preparation process of aloe-emodin antibacterial microcapsules. With the variety and concentration of emulsifiers as the changing factors, three different emulsifiers, namely sodium dodecyl benzene sulfonate SDBS, OP-10, and Tween-80, were selected to explore the effects of emulsifier type and microcapsule loading on the physicochemical and the antibacterial properties of waterborne paint films, and the morphology, chemical composition, antibacterial properties, optical properties, and roughness of the paint films were tested and analyzed. The results showed that all the emulsifiers with 3.0% concentration in the microencapsulation preparation were better than 1.0%. The performance of the microencapsulated varnish films prepared with the addition of the three emulsifiers had advantages and disadvantages, with the highest antibacterial rates of 77.1%, 55.4%, and 65.9% for Escherichia coli and 70.0%, 63.9%, and 60.7% for Staphylococcus aureus, respectively. The antibacterial properties of the microencapsulated varnish film prepared by adding SDBS emulsifier were slightly above those of the other two groups. The three sets of paint films’ color differences rose, the gloss reduced, the rate of light loss increased, the rate of light transmission fell, and the roughness increased with an increase in microencapsulated content. Aloe-emodin microcapsules enable the water-based coating to have antibacterial properties, expanding the application range of water-based coatings. Full article

In this study, the photocatalytic effect of TiO2 (1 wt. % and 3 wt. %) deposited on the surface of sintered cathode ray tube glass was examined, as well as its effect on an E. coli strain (BL21(DE3)). DTA analysis indicated the sintering temperature for samples to be 820 °C while scanning electron microscopy (SEM)showed an intimate contact and a strong interface between the support and photocatalyst. Near-ambient pressure X-ray photoelectron spectroscopy (NAP-XPS) was employed to establish the chemical and bonding environment of the samples. The investigations of the bacterial viability were conducted using flow cytometry, a specific cellular viability assay, while bacterial growth was measured using the turbidimetric method. The experimental results show the influence of the TiO2 concentration on the bacterial inactivation process: higher concentrations (3% wt.) have a bactericidal effect in the long term, whereas lower concentrations (1% wt.) render them inactive for a shorter time in the exponential growth stage. The preliminary results were used to calculate the efficiency of microbial inactivation and the parameters of the kinetics of inactivation using ANOVA software. The results indicate that this material could be an effective solution for water disinfection. Full article
