“…Application of carbon nanofibrous films in oily/water treatments is advantageous over organic polymer-based sorbents for being stable in harsh conditions (acidic or basic media). However, very few studies have been reported on fabrication of carbon nanofibers for oily water treatments [ 135 ]. A pioneering work using electrospun nanofibers conducted by Liu et al, introduced a flexible and recyclable electrospun carbon nanofibrous film for oil-water separation (water contact angle of 155.3°, oil uptake capability of 138.4 g/g −1 for silicone oil) [ 136 ].…”

Electrospinning is one of the most successful and efficient techniques for the fabrication of one-dimensional nanofibrous materials as they have widely been utilized in multiple application fields due to their intrinsic properties like high porosity, large surface area, good connectivity, wettability, and ease of fabrication from various materials. Together with current trends on energy conservation and environment remediation, a number of researchers have focused on the applications of nanofibers and their composites in this field as they have achieved some key results along the way with multiple materials and designs. In this review, recent advances on the application of nanofibers in the areas—including energy conversion, energy storage, and environmental aspects—are summarized with an outlook on their materials and structural designs. Also, this will provide a detailed overview on the future directions of demanding energy and environment fields.

“…However, with the rising concerns on the toxicity of silver (Ag) entrainment into biological systems and the environment it has become necessary for further research on silver-nanoparticles toxicology impact assessment when they coexist with or without their bioavailable ions [74,75]. Noamani et al [70] reviewed the extensive studies that have been carried out on carbon-based polymer nanocomposite membranes for oily wastewater treatment. They reported that incorporating materials such as carbon-nanotubes (CNTs), graphene, graphene-oxide (GO), and carbonnanofibers (CNFs) into polymeric membranes, enhanced the performance output of such membrane systems in terms of permeations, antifouling, and self-cleaning characteristics.…”

“…This study argued that there was an increase in the hydrophilicity of the PES hollow fiber UF membranes when hydrophilic functionalized graphene was Fig. 4 An overview of the optimization of conventional polymeric membranes by nano-doping for improved functionality, cost implications, and smaller environmental footprints [34,70] grafted to G-PANCMI or ultra-wetting graphene, which was successful in the separation of the oil-water mixture, hence presenting the possibility of mitigating the challenges of using polymeric membranes for oil-water separation. Similarly, Liu et al [78] developed a novel antifouling ultralight free-standing reduced GO membrane for oil-in-water emulsion separation.…”

In the past decades, the demand for potable and usable water has been on a continual increase, while its availability has been on an exponential decline. Studies have argued that, by 2050, only a small fraction of the world's population will have access to clean and safe water, thereby exposing a significant portion of the population to a serious water crisis. Large volumes of wastewater are generated yearly, both domestically and industrially, and the necessity to develop effective and efficient strategies and technologies to recover these wastewaters and turn them into safe and reusable waters is a momentous concern among scientists and policymakers. Across the globe, governments are developing approaches and strategies to mitigate both short-and long-term water challenges resulting from various anthropogenic activities that have contributed to the rising degradation of water quality, coupled with the attendant negative impact of natural disasters, increasing urbanization, among others. Notwithstanding, the advancements in nanotechnology have made it possible to engineer novel and innovative polymer-based materials and composites that possess desirable and even predictable properties for targeted applications, which has presented the opportunity for the development of cost-effective nanotechnologies and processes employed in water remediation, reclamation, purification, and treatment processes worldwide. Nevertheless, these innovative technologies and processes have also been shown to have their limitations and challenges in the enhancement of water quality. Herein we survey the current advancement of selected polymer-based membranes and composites and their intervention for the production of safe, potable, and usable water, as well as their limitations, challenges, recommendations, and future perspectives.

“…Carbon-based polymer nanocomposites are versatile materials for a number of purposes such as environmental and energy applications [ 1 , 2 , 3 ]. This is mainly due to the unique properties of carbon-based nanomaterials (such as graphene-based materials) which exhibit high electrical and thermal conductivities, excellent mechanical properties, and light weight [ 4 ].…”

Thermally Reduced Graphene Oxide/Thermoplastic Polyurethane Nanocomposites: Mechanical and Barrier Properties

et al. 2020

View full text Add to dashboard Cite

This work consists of studying the influence of two thermally reduced graphene oxides (TRGOs), containing oxygen levels of 15.8% and 8.9%, as fillers on the barrier properties of thermoplastic polyurethane (TPU) nanocomposites prepared by melt-mixing processes. The oxygen contents of the TRGOs were obtained by carrying out the thermal reduction of graphene oxide (GO) at 600 °C and 1000 °C, respectively. The presence and contents of oxygen in the TRGO samples were determined by XPS and their structural differences were determined by using X-ray diffraction analysis and Raman spectroscopy. In spite of the decrease of the elongation at break of the nanocomposites, the Young modulus was increased by up to 320% with the addition of TRGO. The barrier properties of the nanocomposites were enhanced as was evidenced by the decrease of the permeability to oxygen, which reached levels as low as −46.1%.
