“…A resin is an oligomer, which is a chain formed by the union of monomer units, that will constitute the framework of the cured polymer network [ 55 , 64 ]. It cannot be considered a polymer because the latter is a macromolecule with a much larger number of monomer units [ 65 ], whereas these oligomers usually contain from 1 to 12 repetitive units [ 66 ].…”

Even though there are many photocurable compositions that are cured by cationic photopolymerization mechanisms, UV curing generally consists of the formation of cross-linking covalent bonds between a resin and monomers via a photoinitiated free radical polymerization reaction, obtaining a three-dimensional polymer network. One of its many applications is in the refinish coatings market, where putties, primers and clear coats can be cured faster and more efficiently than with traditional curing. All these products contain the same essential components, which are resin, monomers and photoinitiators, the latter being the source of free radicals. They may also include additives used to achieve a certain consistency, but always taking into account the avoidance of damage to the UV curing—for example, by removing light from the innermost layers. Surface curing also has its challenges since it can be easily inhibited by oxygen, although this can be solved by adding scavengers such as amines or thiols, able to react with the otherwise inactive peroxy radicals and continue the propagation of the polymerization reaction. In this review article, we cover a broad analysis from the organic point of view to the industrial applications of this line of research, with a wide current and future range of uses.

“…Accordingly, some methods, such as using nanoparticles and nano-porous materials and micro-texturing, have been proposed [54][55][56]. These strategies for lubricant retention in slippery coatings were not used in most relevant studies regarding the fabrication of such coatings for electrical applications.…”

Icephobicity and electrical assessment of slippery coating impregnated with a stabilized hydroxyl-terminated lubricant for high voltage insulation application

In cold climate conditions, insulators are subjected to ice accretion that could affect their electrical performance and consequently lead to power outages. Besides icing, other outdoor factors, such as UV, rain, and pollution, could influence their electrical insulation efficiency. Slippery liquid-infused coatings have attracted great attention due to their icephobic applications. However, the problems caused by lubricant depletion could restrict their service time and thus limit their applications. Here, lubricant-loaded carrier (LLC) powders were first, obtained by applying negative pressure through a three-step procedure.Then, hydroxyl-terminated silicone oil carriers were impregnated into a blend of polydimethylsiloxane (PDMS) and alkoxy-siloxane resin. The fabricated coatings exhibited long-lasting icephobic characteristics, resulting in reduced amount of ice accumulated on the surfaces. This reduction in ice adhesion is related not only to the slippery behavior of the coatings but also the formation of unfrozen hydrogen-bonded 2 molecules. The coatings exhibited desired stability against weathering conditions, such as UV exposure and humidity. The electrical characteristics of the prepared coatings were evaluated using dielectric spectroscopy, flashover, condensation, and inclined plane tests.Accordingly, the coatings containing lubricant-loaded carriers showed increased flashover voltage in dry, wet, and polluted states and reduced leakage currents in the condensation test.
