“…Over the past decades, the method of using CIs in paint and varnish system has been actively developed. It consists of placing it in nano-or microcontainers, which prevents the negative effect of organic CIs on the functioning of the coating, while maintaining the increase in the efficiency of metal corrosion protection [78][79][80][81].…”

“…As an example, let us consider the possibility of producing silica particle containers with a high content of sodium N-oleoylsarcosinate (SOS) loaded at the sol-gel stage of particle synthesis by using its micelles as a template [81]. It is known that the content of the templating functional compound in such containers reaches 1 g or more per 1 g of SiO 2 .…”

A brief review of the main scientific areas of research and development of efficient corrosion inhibitors of metals (CIs) and their application methods is given. Temporary protection against atmospheric corrosion of steel pipes and equipment for storage (at least one year) or during transportation is often achieved by passivation using aqueous solutions of non-toxic CIs. They efficiently protect not only steel, but also copper or aluminum alloys; therefore, they successfully replace environmentally hazardous passivating solutions, not only nitrite but also chromate ones. Such solutions are often based on salts of higher carboxylic acids, for example, oleic acid or oleoylsarcosine. Temporary protection includes the use of vapor phase CIs, which, in addition to traditional volatile CIs, include the recently proposed so-called chamber CIs. A relatively new and rapidly developing method of temporary protection of metals is the superhydrophobization of their surface, which provides water contact angles θ above 150°. CIs are used in solutions of strong acids that are injected into the reservoir to increase oil production and in H 2 S-containing media in the fight against corrosion and hydrogenation. Examples of CI applications in paint systems, and more precisely in the primer layer, where they are introduced being immobilized in micro or macro containers to prevent the adverse effect of a CI on the coating while maintaining a high efficiency of metal corrosion protection, are considered. To prevent the destruction of high-pressure gas pipelines, it is important to slow down not only steel corrosion, but also its stress corrosion cracking (SCC). The properties of CIs that are necessary for their use in polymer coatings to reduce the accident incidence rate due to SCC on gas pipelines are discussed.

“…Works on the microcapsulation of sodium oleoylsarcosinate are also of interest [71]. The choice of sodium oleoyl sarcosinate is explained by its high adsorption and inhibitory ability with respect to iron, copper, zinc, D16 aluminum alloy and other metals [72][73][74].…”

One of the most promising methods to improve the protective ability of coatings is the use of microencapsulated corrosion inhibitors (MCI) and active additives in their composition. Microencapsulation technology greatly simplifies the process of compounding the polymer protective coating and allows to isolate the active components from the reactive groups of polymer resins and hardener at the stage of curing, correctly form the polymer base of the coating and avoid the negative effect of the inhibitor on the adhesion of the coating to the protected substrate. The review discusses the main methods and techniques for producing micro-and nanocapsules. The basic requirements for the quality and complex characteristics of micro-and nanocapsulated corrosion inhibitors are presented. The advantages and disadvantages of capsules using solid materials, such as powders of natural and synthetic origin, carbon nanotubes, nanotubes based on clay materials and capsules with a liquid core and a polymer shell, for example, epoxy, epoxy, silicone resins, are noted. Description of the mechanism of transfer of the contents of microcapsules in the polymer base of the coating. The possibilities of "intelligent" microcapsules releasing the inhibitor when the pH level changes are considered. Examples of successful scientific and technical solutions for the manufacture and implementation of micro-and nanocapsulated corrosion inhibitors in coatings with specific materials used for the manufacture of microencapsulated corrosion inhibitors are given.

“…As a result, such MSNs are widely used as drug delivery vehicles [ 1 , 4 ] as well as in the creation of various types of coatings. It has been shown, for example (see [ 2 , 5 , 6 , 7 , 8 , 9 ] and the references therein), that the incorporation of MSNs loaded with corrosion inhibitors into polymer coatings can significantly increase the effectiveness of their protective effect. In our opinion, MSNs are also interesting when creating nanocomposites for biomedical applications (e.g., wound dressings or dental materials) [ 5 , 10 , 11 , 12 ].…”

The creation of antibacterial nanocomposites that provide prolonged release of encapsulated drugs is of great interest for various fields of medicine (dentistry, tissue regeneration, etc.). This article demonstrates the possibility of creating such nanocomposites based on sodium alginate and drug-templated mesoporous silica nanocontainers (MSNs) loaded with two bioactive substances. Herein, we thoroughly study all stages of the process, starting with the synthesis of MSNs using antiseptic micelles containing the hydrophobic drug quercetin and ending with assessing the activity of the resulting composites against various microorganisms. The main emphasis is on studying the quercetin solubilization in antiseptic micelles as well as establishing the relationship between the conditions of MSN synthesis and micelle morphology and capacity. The effect of medium pH on the release rate of encapsulated drugs is also evaluated. It was shown that the MSNs contained large amounts of encapsulated drugs and that the rate of drug unloading depended on the medium pH. The incorporation of such MSNs into the alginate matrix allowed for a prolonged release of the drugs.
