Enhanced ultraviolet‐protectivetextiles based on reduced graphene oxide‐silver nanocomposites on polyethylene terephthalate usingultrasonic‐assisted in‐situthermal synthesis

Abstract

The present research develops a novel in-situ synthesis method to produce a high performance nanocomposite coating on polyethylene terephthalate (PET) fabric as an enhanced UV-protective textile. Reduced graphene oxide-silver (rGO-Ag) multi-layer nanocomposite was in-situ synthesized on the PET fabric through the direct redox reaction between the Ag + ions and GO sheets by using ultrasonic and thermal treatment. The X-ray diffraction and field emission scanning electron microscope confirmed that the well-synthesized Ag nanoparticles (AgNPs) loaded on PET fabric in presence of the GO sheets by using ultrasonic waves without reducing and capping agents. In this research, GO sheets were used as reducing and capping agents along with the ultrasonic treatment at low temperature condition. The final average size of the synthesized AgNPs in solution, on the PET surface and in the freestanding film is lower than 100 nm. The ultraviolet protection factor (UPF) of the PET fabric incorporating multi-layer rGO-Ag nanocomposite as a UV blocking system could reach to 6145.66, up to the 183-fold higher than uncoated PET fabric (UPF 33.63). In addition, the final fabric demonstrates a good air permeability and antibacterial properties due to the effective coating of rGO-Ag nanocomposite on PET surface.

Recent Advances of Sustainable Textile Fabric Coatings for UV Protection Properties

“…One of the widely used nanoparticles in fabrics treatments is TiO 2 NPs due to its merits such as being antibacterial, self-cleaning and an excellent UV absorber [51,52]. This is due to the suitability of its band gap for absorption of rays in the range from 280-400 nm [12,15,[53][54][55]. Attia et al reported well dispersed TiO 2 NPs-and ZnO NPs-based textile fabrics coating individually and synergistically for various textile fabrics as shown in Figure 5 [12].…”

A focused review on recycling and hydrolysis techniques of polyethylene terephthalate

“…This broad commercial use is due to the attractive physical and chemical properties of PET including high transparency, crystallization rate, high thermal stability, high mechanical properties, and high oxygen barrier. [1][2][3] It is estimated that the PET market will have a globally annual growth of 4.2% over the 5-year period from 2019 to 2024, increasing to 11 billion dollars in a period time of 2019-2024. 4 The two most used commercial processes for PET synthesis are presented in Figure 1; (i) esterification of terephthalic acid (TPA) with ethylene glycol (EG) followed by polycondensation and (ii) transesterification of dimethyl terephthalate (DMT) with EG followed by polycondensation.…”

“…16,17 Among all above materials; graphene-coated electroconductive textiles have been considered due to its ease of fabrication, high electrical conductivity, high surface area, great mechanical and wearing properties. 2,[18][19][20][21] It has been demonstrated that graphene oxide (GO), shows better coating properties on textiles due to the interaction between surface functional groups possibly via covalent, Van de Waals, and hydrogen bonding. 22,23 Reduction step is necessary to in situ convert of insulating GO into conductive reduced graphene oxide (rGO) through restoration of the honeycomb structure.…”
