“…Для нанесения полиэлектролитных слоев на частицы использовали метод полиионной сборки, который осуществлялся последовательной обработкой разноименно заряженными биосовместимыми полиэлектролитами -хитозаном и ксантановой камедью. Проведенные калориметрические исследования позволили выявить концентрационные параметры (соотношения), при которых начинается образование стехиометрического полиэлектролитного комплекса, то есть формирование плотной полиэлектролитной оболочки капсулы [37]. Получение полых полиэлектролитных оболочек -проницаемых капсул -осуществляли путем растворения ядер СаCO3 при добавлении тринатриевой соли этилендиаминтетрауксусной кислоты (ЭДТА) [38].…”

The results of studies aimed at the creation of new functional textile materials through the use of microencapsulated TE (textile excipients) and metal nanoparticles, metal and non-metal oxides, as well as clays of natural origin were summarized. The developed methods for the synthesis of capsule shells of various architectures, including natural and synthetic polyelectrolytes, were presented. The technologies for encapsulation of functional preparations for aromatic, repellent and antibacterial finishing of textile materials were described. A description of the formation of microcapsules based on a highly active repellent drug - alpha-cypermethrin is given. An antimicrobial preparation containing silver nanoparticles has been developed, and recommendations for its use have been given. The production of silver nanoparticles were based on the reduction of metallic silver from silver nitrate using reducing agents such as glucose, glyoxal, and sodium dithionite in various concentrations. The sizes of synthesized particles vary from 145 to 2 nm. Modifying compositions based on synthetic polyelectrolytes and new complex compounds with predictable prolonged stability, functional substances and macrocycles (cyclodextrins (CD) and crown ethers) have been obtained. A technique was presented for the synthesis and strong fixation on cellulose fiber by introducing silver ions into the cavity of β-cyclodextrin of bioactive Ag-containing preparations with nanometer-sized particles. Methods for obtaining nanosized particles of zinc oxide were presented. Zinc acetate and zinc chloride were used as precursors. The sizes of the obtained nanoparticles are 70-90 nm. The technological bases for obtaining polyfunctional coatings on textile materials by impregnation and printing methods using polymers were described. The resulting coatings exhibit enhanced antibacterial and self-cleaning properties. The polyfunctionality of the action of fluorinated aluminosilicate in the processes of textile chemistry was shown.

“…Nanofibrous polyamide 6 (PA6) non-vowens were integrated with several sulfonphthaleine-based halochromic dyes and investigated for their leaching mechanisms. PDADMAC is a complexing agent that has been used to suppress the leaching of the dye from the polymeric matrices, mostly used in textile industry [ 28 ]. It prevents the migration of dye molecule from the matrix by the ionic interactions [ 29 ].…”

Responsive materials, i.e., smart materials, have the ability to change their physical or chemical properties upon certain external signals. The development of nanofibrous halochromic materials, specifically combining the pH-sensitive functionality and unique nanofiber properties, could yield interesting new applications, especially when the common problem of dye leaching is successfully tackled. Therefore, in this article, we studied the fabrication process of polysaccharide-based halochromic nanofibrous materials by using a combination of various halochromic dyes (bromothymol blue, bromocresol green, and thymol blue) and cellulose acetate in a spinning solution using a one-pot strategy. The inhibition of leaching was addressed by using a complexing agent: poly-diallyl-dimethylammonium chloride (PDADMAC). The preparation of hybrid spinning solutions, their characterization, and ability to form continuous nanofibers were studied using a high production needle-less electrospinning system. The produced hybrid solutions and nanofibers were characterized, in terms of their rheological properties, chemical structure, morphology, and functionality. Fabricated nanofibrous halochromic structures show a clear color change upon exposure to different pH values, as well as the reduced leaching of dyes, upon the addition of a complexing agent. The leaching decreased by 61% in the case of bromocresol green, while, in the case of bromothymol blue and thymol blue, the leaching was reduced by 95 and 99%, respectively.
