In this logic, smart polymers propose materials that react to many stimuli such as pH, temperature, light, magnetic and electric fields, light intensity, biological molecules, etc. Smart polymers have gained an enormous amount of attention in this new era due to their countless applications in zones including biosensors, switchable wettability, actuators, and several therapeutic and environmental-based applications. Several rigorous researches have been carried out to improve smart polymers using different stimuli-responsive polymeric moieties. This chapter summarizes the basic introduction/classification of smart polymers and their importance at a nanocomposite level. Some introduction related to the most familiar applications of smart polymer nanocomposite materials are also summarized in this chapter.

As such, the need for the materials is to be durable, flexible, and controllable. Since the discovery of polymers, their life cycle was generally going on or recycled even when exposed to heat, light, biological, or chemical attack. When required, polymers can be doped or mixed with other compounds to make an even enhanced composite material. This enables much more versatility to an already great material. This method also improves polymer’s properties by adding properties that belong to the other compounds. Naturally, some polymers are degradable which make it useful in biomedical application. Biomedical materials need to be biocompatible with the host so that it can properly function. Biocompatible materials are those which are not only nontoxic but also capable of performing to its standard regardless...

The theoretically predicted (2360 m2 g−1) and experimentally measured surface areas (∼700 m2 g−1) of GO make them attractive for environmental applications. In material science the research on graphene and their scaled-up reliable production have attracted a lot of interest. The possibility of conjugation of graphene and GO with inorganic nanomaterials to form composite has received particular attention for the advancement of wastewater treatment process. This chapter describes the preparation of magnetite GO and outlines the latest application in dispersive solid-phase extraction for environmental water remediation. It also highlights the challenges which limit their large-scale field applications and further challenges.

In comparison to undoped graphene, the graphene-based nanocomposite doped with different materials (metals, metal oxides, sulfides, alloys, and polymeric materials) are more efficient for energy storage purposes. In this chapter, we present an overview on metal-doped graphene-based nanocomposites and also highlight the future challenges and their application for energy storage including hydrogen storage and other gases, supercapacitors and lithium–sulfur, lithium–ion, lithium–air batteries, and conversion (oxygen reduction reaction for fuel cells). The chapter further discusses the valuable properties of graphene nanocomposites such as porosity, availability of free electron, large surface area, etc. These properties offered a valuable direction in the designing of devices which can produce as well as store energy.

Water pollution is becoming a severe problem for the whole world from small villages to big cities. The toxic metals and organic dyes pollutants are considered as significant contaminants that cause severe hazards to human beings and aquatic life. The microbial fuel cell (MFC) is the most promising, eco-friendly, and emerging technique. In this technique, microorganisms play an important role in bioremediation of water pollutants simultaneously generating an electric current. In this review, a new approach based on microbial fuel cells for bioremediation of organic dyes and toxic metals has been summarized. This technique offers an alternative with great potential in the field of wastewater treatment. Finally, their applications are discussed to exp...

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 puri...

An improved sol-gel method was used to prepare these particles using titanium isopropoxide as a precursor and their photocatalytic activity was tested by studying the degradation of three different types of organic pollutants (acid blue 129, tinidazole, and metalaxyl). The prepared samples were characterized with standard analytical techniques such as X-ray diffraction (XRD), scanning electron microscopy (SEM), and UV-Vis spectroscopy. The XRD analysis suggests the anatase phase with a crystalline nature. The SEM image of undoped TiO 2 exhibits high roughness and irregular shaped particles. The doped TiO 2 particles showed smaller size than undoped TiO 2 with regular shaped and high surface area. The doped TiO 2 particles also show lower band gap energy than undoped. The photocatalytic results indicate that TiO 2 with a dopant concentration of 0.75% for all metal ions shows the highest photocatalytic activity. Moreover, the Mn-doped TiO 2 (0.75%) degraded metalaxyl more efficiently as compared with other studied pollutants.
