“…During the dip coating, a film substrate is immersed into a bath containing coating materials at a constant speed (immersion); When the substrate is mostly or fully immersed, it remains in the coating solution for a designated time (dwelling); The film substrate is then pulled out from the bath and a thin layer of coating starts to form on it (withdrawal); Once fully withdrawn, excess liquid is drained from the substrate surface and solvent begins to evaporate, leaving behind a dry thin film (drying) (Kakaei et al., 2019). The coating thickness is primarily controlled by the withdrawal speed and the properties of the coating solution, which can range from a few micrometers to hundreds of micrometers (Mohammadzadeh et al., 2020). For this method requires no complex equipment, dip coating has been extensively applied at laboratory scale to manufacture antimicrobial‐coated films, either alone or in combination with LbL assembly or sol‐gel technique to achieve desired coated films.…”

Antimicrobial food packaging involves packaging the foods with antimicrobials to protect them from harmful microorganisms. In general, antimicrobials can be integrated with packaging materials via direct incorporation of antimicrobial agents into polymers or application of antimicrobial coating onto polymer surfaces. The former option is generally achieved through thermal film‐making technology such as compression molding or film extrusion, which is primarily suitable for heat‐stable antimicrobials. As a nonthermal technology, surface coating is more promising compared to molding or extrusion for manufacturing food packaging containing heat‐sensitive antimicrobials. In addition, it also has advantages over direct incorporation to preserve the packaging materials’ bulk properties (e.g., mechanical and physical properties) and minimize the amount of antimicrobials to reach sufficient efficacy. Herein, antimicrobial food packaging films achieved through surface coating is explored and discussed. The two components (i.e., film substrate and antimicrobials) consisting of the antimicrobial‐coated films are reviewed as plastic/biopolymer films; and synthetic/naturally occurring antimicrobials. Furthermore, special emphasis is given to different coating technologies to deposit antimicrobials onto film substrate. Laboratory coating techniques (e.g., knife coating, bar coating, and spray coating) commonly applied in academic research are introduced briefly, and scalable coating methods (i.e., electrospinning/spraying, gravure roll coating, flexography coating) that have the potential to bring laboratory‐developed antimicrobial‐coated films to an industrial level are explained in detail. The migration profile, advantages/drawbacks of antimicrobial‐coated films for food applications, and quantitative analyses of the reviewed antimicrobial‐coated films from different aspects are also covered in this review. A conclusion is made with a discussion of the challenges that remain in bringing the production of antimicrobial‐coated films to an industrial level.

The primary components of SOFCs are the anode, cathode, and the electrolyte. Anode is critical in achieving the effective electrochemical oxidation of fuel; thus, its performance can be improved using homogenous powder synthesized through an appropriate method. Various synthesis methods, including solidstate reaction and wet chemical methods have been used to synthesize anode materials. However, each technique has several advantages and disadvantages.Given that anode is a porous electrode, few criteria, such as high conductivity, tolerance towards carbon deposition, chemical stability, and thermal stability, must be fulfilled. Researchers also modified the existing synthesis method to improve the performance of the anode. In addition, various anode fabrication techniques including physical and colloidal deposition techniques are briefly discussed to understand their effect on the performance of the deposited layers.The aim of this review is to discuss the various anode synthesis and deposition techniques and their influence on the properties and performance of SOFCs.

“…Dip coating is a low-cost and simple technique that allows easy adjustment of the coating smoothness and thickness and application of layers as thin as a few microns. 197 The process includes several stages: constant-speed immersion of a substrate into polymer solution, its presence in the solution, removal of the substrate at a constant speed, solvent evaporation, and drying. Wang and co-workers used this technique to deposit long-term copolymer coatings containing QACs and phosphorylcholine (PC) groups on glass and polylactic acid substrates.…”

From Antibacterial to Antibiofilm Targeting: An Emerging Paradigm Shift in the Development of Quaternary Ammonium Compounds (QACs)

In a previous development stage, mostly individual antibacterial activity was a target in the optimization of biologically active compounds and antiseptic agents. Although this targeting is still valuable, a new trend has appeared since the discovery of superhigh resistance of bacterial cells upon their aggregation into groups. Indeed, it is now well established that the great majority of pathogenic germs are found in the environment as surface-associated microbial communities called biofilms. The protective properties of biofilms and microbial resistance, even to high concentrations of biocides, cause many chronic infections in medical settings and lead to serious economic losses in various areas. A paradigm shift from individual bacterial targeting to also affecting more complex cellular frameworks is taking place and involves multiple strategies for combating biofilms with compounds that are effective at different stages of microbiome formation. Quaternary ammonium compounds (QACs) play a key role in many of these treatments and prophylactic techniques on the basis of both the use of individual antibacterial agents and combination technologies. In this review, we summarize the literature data on the effectiveness of using commercially available and newly synthesized QACs, as well as synergistic treatment techniques based on them. As an important focus, techniques for developing and applying antimicrobial coatings that prevent the formation of biofilms on various surfaces over time are discussed. The information analyzed in this review will be useful to researchers and engineers working in many fields, including the development of a new generation of applied materials; understanding biofilm surface growth; and conducting research in medical, pharmaceutical, and materials sciences. Although regular studies of antibacterial activity are still widely conducted, a promising new trend is also to evaluate antibiofilm activity in a comprehensive study in order to meet the current requirements for the development of highly needed practical applications.
