Polymeric nanocomposites are the materials incorporating nanosized inclusions into the polymer matrixes. The result of the addition of nanoparticles/fibers is a drastic improvement in properties that may include mechanical, electrical, thermal conductivity, or even the acoustical properties. Polymer nanocomposites have spawned huge interest for the development of high‐performance products such as lightweight sensors, thin‐film capacitors, batteries, flame retardant products, biodegradable and biocompatible materials, and so on. The field of polymer nanocomposites has been at the forefront of research in the polymer community for the past few decades and an extremely large number of scientific papers have been published. Nevertheless, application‐oriented guidelines for selecting the ecofriendly nanocomposites for advanced industrial applications are missing in the state of the art. This review article summarizes the current state‐of‐the‐art polymeric nanocomposites, highlighting prominent nanofillers categorized based on their applications, origins, dimensional characteristics, and so on. Each filler type contains a short description of its main feature together with the most relevant and potential applications. To address the global concern about nondegradable wastes, novel green alternatives of each nanofiller type are discussed. Special attention is also given to the biocompatibility properties of the composites. This study provides a state‐of‐the‐art road map to select multifunctional polymeric nanocomposites from huge varieties for advanced industrial applications.

“…The porous structure of the films was beneficial for light reflection [35], and provided a channel for the MO molecules to adsorb on the surface of the ZnO incorporated in the polymer matrix. The high surface roughness of the films improved their hydrophilic properties thus enhancing the interaction of the films with water, oxygen, and the contaminants [36]. Both properties provided favorable conditions for an efficient photodegradation process.…”

Abstract:A facile and effective technique to immobilize photocatalyst nanoparticles by incorporating zinc oxide (ZnO) into polyethersulfone polymeric films by means of a phase inversion technique is reported. The degradation study of methyl orange (MO) dye was performed using a series of ZnO-embedded polymer hybrid systems. The photoactivity of the films increased in parallel with increased ZnO loading up to 17 wt%. The photodegradation process followed a pseudo first-order kinetics with an achievement of almost 100% MO removal in original conditions. The PZ-17 film demonstrated an excellent and comparable degradation performance up to five cycles, signifying the reliability of the film photocatalyst against ultraviolet irradiation and degradation.

“…Thus, various strategies need to be adopted so as to narrow the wide band gap (suppressing electron-hole pair recombination) making the process efficient in visible light as well. These strategies include doping of metal oxides [189], development of the heterojunction materials [190], modulation of defect sites [191], precise control of the reaction stoichiometry, functionalization of nanomaterials [192] and tailoring of metal oxide [193] as per reaction requirements. In this viewpoint, all relevant studies employing metal oxides are highlighted and their applications for pharmaceuticals removal are only discussed.…”

“…Similarly, a regenerated cellulose/TiO 2 composite membrane was evaluated for its photocatalytic activity to degrade organic contaminants [192]. The resulting inorganic-organic nanocomposite membrane had an ultrafine nano-porosity, high strength, good absorption efficiency while the photocatalytic efficiency was improved further using nitrogen-doped TiO 2 .…”

Background: The limitless presence of pharmaceutical contaminants in discharged wastewater has emerged as a threat to aquatic species and humans. Their presence in drinking water has although raised substantial concerns, very little is known about the fate and ecological impacts of these pollutants. As a result, these pollutants are inevitably introduced to our food chain at trace concentrations. Unfortunately, the conventional wastewater treatment techniques are unable to treat pharmaceuticals completely with practical limitations. The focus has now been shifted towards nanotechnology for the successful remediation of these persistent pollutants. Thus, the current review specifically focuses on providing readers brief yet sharp insights into applications of various nanomaterials for the removal of pharmaceutical contaminants. Methods: An exhaustive collection of bibliographic database was done with articles having high impact and citations in relevant research domains. An in-depth analysis of screened papers was done through standard tools. Studies were categorized according to the use of nanoscale materials as nano-adsorbents (graphene, carbon nanotubes), nanophotocatalysts (metal, metal oxide), nano-filtration, and ozonation for promising alternative technologies for the efficient removal of recalcitrant contaminants. Results: A total of 365 research articles were selected. The contemporary advancements in the field of nanomaterials for drinking and wastewater treatment have been thoroughly analyzed along with their future perspectives. Conclusion: The recommendations provided in this article will be useful to adopt novel strategies for on-site removal of the emerging contaminants in pharmaceutical effluents and related industries.
