Abstract:The paper presents a comparative analysis of the surface structure and morphology of hydrophobic coatings formed on a polyester fabric from various types of low molecular weight tetrafluoroethylenes by a new method. The low molecular weight compounds used include: ultrafine polytetrafluoroethylene of the FORUM® trademark prepared through thermo-gas-dynamic decomposition of industrial polytetrafluoroethylene waste, and tetrafluoroethylene telomers, synthesized by radiation-chemical initiation from fluoromonomer… Show more
“…Water-repellent properties (hydrophobicity) are important for a number of household and special purpose fabrics. It is known that giving a high hydrophobicity to a fabric, as well as to any solid [202][203][204][205][206], can be achieved through the combined action of two factors. The first factor is a decrease in surface energy, by changing the chemical composition of the surface.…”
This review summarizes the results of research published in recent decades on the main directions in the functionalization of fibrous materials using surface modification. Methods for thepreliminary activation of the surface of fibrous materials are described, allowing increasing the adhesion of modifiers. The features of the formation of functionalizing coatings on fibrous materials in comparison with other substrates are analyzed. Some specific methods for evaluating the effectiveness of the surface modification inherent in fibrous materials are considered. Particular attention is paid to giving fibrous materials antimicrobial properties, photoactivity, the ability to protect against ultraviolet radiation, and hydrophobicity.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
