ABSTRACT
Carbon nanotubes (CNTs) are distinctive pseudo-one-dimensional nanostructured material formed by rolling up graphene sheets with a hexagonal lattice draped up into a seamless cylinder. The structural exclusivity and the captivating estates of carbon nanotubes have guided intense research efforts in exploring their potential applications. CNTS, a nanoscopic form of carbon was exploited expansively for energy storage devices like supercapacitors owing to their additional surface area and chemical limpness. In addition to remarkable structural properties, carbon nanotubes possess many astonishing properties, such as elevated aspect ratio, incredible electrical and thermal conductivity, chemical permanence, low mass, and superior mechanical assets. Also, carbon nanotubes are amongst the toughest and highly robust materials known in nature. Hybrid materials of carbon comprising CNTs, and polymers have been exposed to be one of the fantastic electrode materials for supercapacitors and the harmonious effects of CNTs deliver brilliant electrochemical attributes compared with specific constituent CNTs. Porous arrangement formed by the accessible spaces amid entangled nanotubes empowers comfortable admittance of electrolyte ions to the electrode/electrolyte interface. Furthermore, due to the resilience of the nanotube skeleton, slightly or even no binder is required, unlike traditional carbon materials. CNTs may be additionally modified with—COOH functional groups to generate moieties consistent with the electrolyte solvent and more hydrophilicity. This chapter will provide comprehensive and efficient coverage on the structure, properties, fabrication strategies of CNT polymer composites, their energy storage, and supercapacitance applications.
