This study demonstrates a simple and fast method to integrate superhydrophobicity, UV protection, and photothermal effect onto PET fabrics. The surface of PET fabric forms a hierarchical rough structure through in situ oxidative polymerization of the pyrrole (Py). The 1,4conjugate addition reaction between pentaerythritol tetraacrylate, 3aminopropyltriethoxysilane, and octadecyl acrylate not only endows the PET fabric with superhydrophobicity but also forms a cross-linked network structure which improves the stability of multifunctional coatings on the surface of the PET fabric. In addition, the wettability of the prepared PET fabric is investigated by adjusting the Py monomer and octadecyl acrylate concentration. The results reveal that the prepared PET fabrics exhibit obviously superhydrophobic behavior with a contact angle of 155.8°. The surface temperature of the superhydrophobic PPy/PET fabric can rise to 91 °C under a simulated sunlight which is much higher than the pristine PET fabric, while reaching basically the same steady-state in five heating/cooling cycles. The prepared PET fabric also possesses excellent self-cleaning, UV shielding, and solar light absorption performances. Furthermore, the superhydrophobic PET fabric exhibited excellent stability against 180 °C high temperature, strong UV radiation, different pH solutions and organic solvent erosion, 8 h washing tests, and 25 sandpaper abrasion cycles. These findings provide a path for the future development of multifunctional fabrics using fluorine-free environmentally friendly materials.

Nanotechnology is a powerful tool for engineering functional materials that has the potential to transform textiles into high-performance, value-added products. In recent years, there has been considerable interest in the development of functional textiles using metal nanoparticles (MNPs). The incorporation of MNPs in textiles allows for the obtention of multifunctional properties, such as ultraviolet (UV) protection, self-cleaning, and electrical conductivity, as well as antimicrobial, antistatic, antiwrinkle, and flame retardant properties, without compromising the inherent characteristics of the textile. Environmental sustainability is also one of the main motivations in development and innovation in the textile industry. Thus, the synthesis of MNPs using ecofriendly sources, such as polysaccharides, is of high importance. The main functions of polysaccharides in these processes are the reduction and stabilization of MNPs, as well as the adhesion of MNPs onto fabrics. This review covers the major research attempts to obtain textiles with different functional properties using polysaccharides and MNPs. The main polysaccharides reported include chitosan, alginate, starch, cyclodextrins, and cellulose, with silver, zinc, copper, and titanium being the most explored MNPs. The potential applications of these functionalized textiles are also reported, and they include healthcare (wound dressing, drug release), protection (antimicrobial activity, UV protection, flame retardant), and environmental remediation (catalysts).

Conductive polymer-textile composites with electric heating features were developed by the in-situ polymerization of polypyrrole on wool-felt fabrics. In particular, the amount and uniformity of polypyrrole deposition inside the fabrics was controlled by consecutive cycles of layer-by-layer (LBL) in-situ polymerization. To analyze the interaction principle of wool fiber and polypyrrole and to explore the processing conditions that can maintain the mechanical properties of the composites, the appearance, add-on, and electrical heating performance were evaluated according to the number of LBL cycles. The polypyrrole formed spherical particles on the wool-felt after polymerization. As the number of LBL cycles increased, more polypyrrole particles were deposited. In the case of mechanical properties, the tensile strength and bending rigidity increased with the polypyrrole deposition, and the strain decreased; however, the difference according to the number of LBL cycles was insignificant. However, the electrical properties were implemented in the polypyrrole-wool composites by polymerization, and a rapid decrease in the surface resistance was observed until the second LBL cycle. In the case of electrical heating performance, the surface temperature increased by up to 15.5 ℃ when 12 V voltage was applied, and the surface temperature increased linearly as the number of LBL cycles increased. This electrical heating performance maintained a high temperature for a certain period, even after removing the voltage, owing to the low thermal conductivity of the wool fiber. In addition, the polypyrrole conductive layer maintained excellent conductivity even after repeated abrasion owing to the improvement in uniformity by the LBL cycles.
