“…Another strategy is the phosphorylation of chitosan to introduce phosphorus moieties as a flame retardant. In this case, phosphorus and MNPs were selected for flame-retardant properties, and chitosan and Ag were selected for antibacterial activity [ 54 ].…”

“…A significant improvement was observed with the addition of AgNPs and phosphorylated chitosan, showing good resistance to bacterial growth. Flame-retardant properties were also improved with the addition of phosphorylated chitosan and AgNPs [ 54 ]. Mogrovejo-Valdivia et al also produced a polyester dressing material where a non-woven material was treated with chitosan and cyclodextrin by crosslinking with citric acid in a pad–dry process before soaking in an Ag sulfate solution.…”

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).

“…In continuation of our efforts in the design and production of innovative polymeric compounds (Mehdipour-Ataei and Hatami 2007;Hatami et al 2020Hatami et al , 2022Mehdipour-Ataei et al 2009), we targeted the fabrication of phosphorylated chitosan/modified alumina nano-additives for a unique PET polymer matrix. Based on the experimental experiences in the preparation of nanocomposites, the hanging over of the inorganic nanostructure by in-situ chemical process on second polymeric media could improve the chemical and physical properties of final nanocomposites due to the good dispersion of nanostructures in the final matrix.…”

“…Based on the experimental experiences in the preparation of nanocomposites, the hanging over of the inorganic nanostructure by in-situ chemical process on second polymeric media could improve the chemical and physical properties of final nanocomposites due to the good dispersion of nanostructures in the final matrix. In our previous study (Hatami et al 2022), the fabrication of PET/phosphorylated chitosan/silver nanocomposites was achieved. Due to the simultaneous good antibacterial and thermal properties of prepared nanocomposites, in this study the authors decided to change the nanostructure in additive formulation to compare the novel nanocomposites with the previous one.…”

In this research, a new generation of ternary nanocomposites based on poly(ethylene terephthalate) (PET), phosphorylated chitosan and surface modified alumina nanoparticles were fabricated in four steps. The phosphorylation process was targeted for the insertion of phosphorus moieties as a flame retardant agent in the final PET nanocomposite. Likewise, environmentally friendly nano-alumina was used for PET matrix to improve the thermal properties of PET in collaboration with organic anchored phosphorus moieties. Alternatively, the presence of bio-safe modified alumina nanoparticles in combination with phosphorylated chitosan simultaneously improved the antibacterial activity and thermal properties of the PET matrix. Furthermore, the effects of the phosphorylated chitosan and alumina nanoparticles on the morphology and thermal properties of nanocomposites were inspected by different approaches. The structure and distribution of the nanoscale particles in PET were analyzed by scanning electron microscopy. In addition, differential scanning calorimetry and thermogravimetric analyses were used for the in-depth evaluation of the thermal properties of prepared nanocomposites. Prepared nanocomposites showed better growth inhibition activities against Escherichia coli bacteria compared to the PET and PET/phosphorylated chitosan samples. Also, the thermal characteristics of prepared nanocomposites were considerably improved.

“…Hosseini et al [8] used silver nanoparticles to improve the electrical conductivity of PVC/SBR as a heterogeneous cationic exchange membrane. Hatami et al [9] studied the effect of a hybrid system (phosphorylated chitosan and silver nanoparticles) on the morphology, thermal behavior, and antibacterial properties of polyethylene terephthalate (PET) samples in different methods. The antibacterial properties of PET nanocomposites can be improved by the insertion of silver nanoparticles into the bulk of the polymer matrix.…”

Influence of Grafting of a Polymeric Antistatic Membrane Doped with Orthophosphoric Acid on its Electrical Properties

Polyvinyl chloride (PVC)/styrene‐butadiene rubber (SBR) antistatic membranes were prepared by two types of grafting, namely, self‐ and chemical grafting processes, using solvent‐casting technique via tetrahydrofuran and toluene as solvents for PVC and SBR, respectively. The membrane modification was carried out by doping orthophosphoric acid (OPA) in the polymer solution. The effect of OPA on the properties of the PVC/SBR membranes was studied in detail with respect to the electrical properties of the antistatic membranes. The electrical conductivities were improved by increasing the OPA content onto membranes. These results suggest that PVC/SBR antistatic membranes doped with OPA can be utilized as promising antistatic material candidates for fabrication of automobile tires and electronic materials.
