“…Therefore, fluorine-free silicone elastomer coatings have been synthesised, such as polymethyl siloxane (PMS), PDMS, hexadecyltrimethox-ysilane (HDTMS), noctyltriethoxysilane (OTES), octadecyltrimethoxysilane (ODTMS), trichloro(octadecyl)silane (OTS), aminosilicone emulsions, and polyvinylsilsesquioxane (PVSQ) [232][233][234]. Plant polyphenols were also used to enhance the superhydrophobic properties of polyamide fabric to achieve self-cleaning [235]. The second mechanism is based on photocatalysis, in which the oxidative decomposition of organic dirt and contaminants adsorbed on the surface of textiles takes place under electromagnetic radiation.…”

According to ISO/TR 23383, smart textiles reversibly interact with their environment and respond or adapt to changes in the environment. The present review and bibliometric analysis was performed on 5810 documents (1989–2022) from the Scopus database, using VOSviewer and Bibliometrix/Biblioshiny for science mapping. The results show that the field of smart textiles is highly interdisciplinary and dynamic, with an average growth rate of 22% and exponential growth in the last 10 years. Beeby, S.P., and Torah, R.N. have published the highest number of papers, while Wang, Z.L. has the highest number of citations. The leading journals are Sensors, ACS Applied Materials and Interfaces, and Textile Research Journal, while Advanced Materials has the highest number of citations. China is the country with the most publications and the most extensive cooperative relationships with other countries. Research on smart textiles is largely concerned with new materials and technologies, particularly in relation to electronic textiles. Recent research focuses on energy generation (triboelectric nanogenerators, thermoelectrics, Joule heating), conductive materials (MXenes, liquid metal, silver nanoparticles), sensors (strain sensors, self-powered sensors, gait analysis), speciality products (artificial muscles, soft robotics, EMI shielding), and advanced properties of smart textiles (self-powered, self-cleaning, washable, sustainable smart textiles).

“…Polyamide fiber, also known as nylon, is renowned for its excellent wear resistance, high tensile strength, and strong resilience. , These properties make it an ideal material for manufacturing items, such as tents and water-resistant medical textiles. , Consequently, there is substantial market demand for water-repellent treatments for polyamide materials. The waterproof agents available in the market can be categorized into fluorinated and nonfluorinated types. − Fluorine-based waterproof agents known for their strong persistence pose environmental concerns due to their bioaccumulative properties and resistance to degradation, primarily because they contain chemicals like perfluorooctanoic acid and perfluorooctanesulfonate. , As a result, global environmental agencies have imposed restrictions on the production and use of long-chain (C8) fluorinated products, leading to a shift toward nonfluorinated water repellents. − …”

As petroleum resources diminish and public environmental consciousness increases, biobased, fluorine-free waterproof agents have become a research hotspot. However, most reported waterproof agents still suffer from poor water resistance and have the drawback of hardening the fabric's hand feel. To address these issues, silanated castor oil (SiCO) was synthesized by castor oil and trimethoxysilane and used to prepare a series of biobased waterborne polyurethanes (SiCO-WPU). Then, SiCO-WPU was finished on the polyamide fabric using a pad−dry−cure procedure. The finishing process was optimized by using the Minitab software. The water repellency tests showed that when the SiCO content was 19.92%, the water contact angle of the SiCO-WPU film increased from 74.8°to 95.8°, and the treated polyamide fabric achieved a contact angle of 138.5°along with a water repellency rating of level 4. In addition, the treated fabric exhibited an 11% decrease in the sliding friction coefficient and a 20% enhancement in the crease recovery angle. Even after 20 washes, the treated fabric still maintained good water repellency and improved the smooth and elastic hand feel. This work holds significant importance for the design and application of sustainable, fluorine-free waterproofing agents in the textile industry.
