Insights into the generation of reactive oxygen species (ROS) over polythiophene/ZnIn₂S₄ based on different modification processing

Abstract

Different ˙O2− and 1O2 were generated from blended and surface-modified samples, respectively.

Functionalization of polymers and nanomaterials for water treatment, food packaging, textile and biomedical applications: a review

“…For instance, the removal of metal cations occurred by the anionic functional moieties via ion exchange, whereby complexation interactions were likely due to uncharged functional moieties. The removal mechanism and the selectivity of polymeric materials could be controlled easily by adjusting the pH of effluent solution (Beaugeard et al 2020;Rivas et al 2018;Gao et al 2018). In this section, firstly the influence of the physical state of polymeric materials and properties of functional moieties toward the implementation in a water treatment process will be discussed.…”

“…The removal of pollutant by water-soluble polymers is widely used through liquid-phase polymer-based retention, which when merged with ultrafiltration, leading to the establishment of the polymer-enhanced ultrafiltration process employing functionalized membranes. The other process is a solid-phase extraction which includes fixedbed or ion exchange column processes, for the removal was employed via insoluble polymeric materials (Gao et al 2017(Gao et al , 2018Graillot et al 2015;Srivastava et al 2018). The hydrophilicity of polymeric materials facilitated a direct interaction of the functional groups with the pollutant in the polymer, enhancing the efficiency of ultrafiltration process, but the removal of the polymer-pollutant complex is a difficult and expensive process.…”

“…So, the exploration of efficient organic antimicrobial agents is of significant importance. Conductive polymers have been extensively explored in numerous applications including organic photovoltaics, sensors, emitting diodes, supercapacitors, transistors and photocatalytic applications. , Recent work with several conductive polymers including polyaniline (PANI), polypyrrole (PPy), and polythiophene (PTh) have shown antibacterial or photo sensitizer activity when incorporated with various inorganic photoactive agents. By extending their light absorption spectrum and promoting the separation of photogenerated electrons and holes, the assemblies photocatalytic activity was enhanced.…”
