“…A curing or cross-linking agent is necessary to set the low molecular weight epoxy oligomer. 13 Curing epoxy resin involves opening the epoxy ring, condensation, and linking the long polymer chains. Careful curing agent selection is also necessary to adjust the final material properties.…”

Epoxies are important thermosetting polymers with exceptional features, which have been successfully employed for coatings. Polyester blends with epoxy enhances their chemical inertness, anti-rusting, toughness, strength, glass transition temperature, and heat stability, Epoxy/polyester blends have been further reinforced with nanocarbon, nanoclay, and inorganic nanoparticles to form nanocomposite coatings. Incorporating nanoparticles in epoxy/polyester has further improved their engineering properties. This review article principally offers state-of-the-art review of epoxy/polyester blends and epoxy-/polyester-based nanocomposite coatings. The epoxy/polyester and epoxy/polyester-based nanocomposites have been employed in non-flammable, anti-corrosion, anti-microbial, and anti-wear coatings in automotive, aerospace, energy, electronics, biomedical, and civil engineering applications. In order to fully utilize their potential, rigorous future attempts are needed for progress in the related technical fields.

рассмотрены вопросы высокоскоростной коммутации сигналов в оптической шине передачи данных на печатной плате. Для создания оптических коммутаторов предлагается использовать каскады волноводных интерферометров Маха–Цендера на основе электрооптических полимеров с фторсодержащими хромофорами в боковой цепи, способными изменять показатель преломления под действием приложенного электрического поля. Такие коммутаторы обладают высоким быстродействием и обеспечивают частоты переключения на уровне 100 ГГц. Предложен подход к формированию одномодовых волноводов и волноводных интерферометров Маха–Цендера в электрооптических полимерах, основанный на лазерном фотоосветлении хромофоров, которое сопровождается уменьшением показателя преломления полимера под действием излучения видимого диапазона. the study considers high-speed switching in an optical bus on a printed circuit board (PCB). We proposed to use cascades of Mach–Zehnder waveguide interferometers to build optical switches. The interferometers are made of electro-optical polymers with fluorine-containing chromophores in the side chain. The substance changes its refractive index when an electric field is applied. Such switches are fast: the switching frequency is up to 100 GHz. The authors also proposed an approach to the manufacturing of single-mode waveguides and Mach–Zehnder waveguide interferometers in electro-optical polymer using laser photo-clarification of chromophores. Visible light decreases the refractive index decrease of the polymer.

“…To create such materials, the chromophores are used that can change the refractive index under the influence of an applied electric field. An electro-optical polymer can be made either by introducing the chromophore molecules into a passive matrix (guest-host system) [4][5][6], or by covalently incorporating them into side chains of polymer macromolecules (side-chain system) [7][8][9]. The latter approach is more promising, since it prevents the agglomeration of chromophores, resulting in decrease of electro-optical coefficient r33.…”

A new electro-optical polymer has been synthesized with a fluorine-containing electrooptical chromophore covalently connected to a fluorine-containing macromolecule. The degree of fluorination of polymer, defined as the ratio of the number of fluorine atoms to the number of fluorine and hydrogen atoms in this macromolecule, is 28.6%. The optical and physical properties of the polymer obtained were investigated. It was shown that it is capable to film formation and can be used to create optical waveguides. It was found that under the action of laser radiation in visible range, the irreversible photobleaching of chromophore in side chain occurs, which is accompanied by decrease in the polymer refractive index. The single-mode channel waveguides in the electrooptical polymer were formed by photobleaching. The polymer possesses increased optical transparency in the telecommunications C-wavelength range and is promising for creation of electro-optical modulators operating in the near IR range.
