“…into polymer ultra-filtration membranes show the formation of amplified membrane on surface of hydrophilicity and fouling resistance [118][119][120]. The antimicrobial material like silver metal particles are also doped with a polymer to produce polymeric membrane to prevent attachment of bacteria and inhibit biofilm production on surface of membrane [121,122]. It served to inactivate viruses and it has also ability to prevent the biofouling of membrane [123].…”

Water is an essential part of life and its availability is important for all living creatures. On the other side, the world is suffering from a major problem of drinking water. There are several gases, microorganisms and other toxins (chemicals and heavy metals) added into water during rain, flowing water, etc. which is responsible for water pollution. This review article describes various applications of nanomaterial in removing different types of impurities from polluted water. There are various kinds of nanomaterials, which carried huge potential to treat polluted water (containing metal toxin substance, different organic and inorganic impurities) very effectively due to their unique properties like greater surface area, able to work at low concentration, etc. The nanostructured catalytic membranes, nanosorbents and nanophotocatalyst based approaches to remove pollutants from wastewater are eco-friendly and efficient, but they require more energy, more investment in order to purify the wastewater. There are many challenges and issues of wastewater treatment. Some precautions are also required to keep away from ecological and health issues. New modern equipment for wastewater treatment should be flexible, low cost and efficient for the commercialization purpose.

“…However, it comes with associated onerous high cost-implications, thus hampering industrialscale application [81]. In addition, a very promising nanomaterial composed of Titanium-dioxide (TiO 2 ) nanoparticles for the treatment of wastewater and water purification process also has the limitation of scalability to commercial viability, hence encumbering its utilization in water remedial and treatment processes [39]. Hence, there is a dire need for future studies to explore innovative fabrication methods for not only benign but also easy-to-fabricate and cost-effective functionalized nanoparticles such as CNT, for a sustainable industrial application/deployment in water treatment processes [62].…”

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.

“…Polymer nanocomposites are widely used in various fields due to their excellent mechanical, thermal, electrical, optical and magnetic properties [37]. The related studies show that the improvement of the properties of polymer nanocomposites depends to a large extent on the dispersion of nano-fillers in polymer matrix, the compatibility of fillers and polymers and the interaction between fillers and polymers [38].…”

In order to solve the problem of dust accumulation on the fin surface of a mine air cooler, a method of preparing super-hydrophobic polyurethane (SPU) coating based on waste cooking oil (WCO) was proposed. Firstly, the polyurethane prepolymer was synthesized with WCO as a raw material, and then the polyurethane prepolymer was modified with amino-terminated polydimethylsiloxane (ATP) to obtain SPU emulsion. The chemical structure and thermal stability of SPU were characterized by infrared spectrum and thermogravimetric analysis. A series of nanocomposites were prepared by combining modified silicon carbide (APT-SiC) particles and SPU emulsions. According to the parameters of pull-off strength, contact angle, sliding angle and thermal conductivity, the filler ratio of nanocomposites was optimized. The test results show that when the content of APT-SiC particles is 20 wt %, super-hydrophobic polyurethane coating can be obtained. The coating has good pull- off strength and thermal conductivity, and the contact angle and sliding angle are 161° and 3°, respectively. In addition, the practical application of the super-hydrophobic polyurethane coating was tested by related experiments. The experimental results show that the coating has good self-cleaning, wear resistance and anti-corrosion performance, can meet the requirements of air coolers in special environments, and has great application prospects.
