Graphene is a wonder nanomaterial which is used in a wide variety of electronics applications because of its excellent electrical, optical, chemical and mechanical properties. For the efficient use of graphene in the preparation of modern electronics devices it is imperative to first prepare a colloidal solution of graphene. Although various techniques are being used for the synthesis of colloidal form of graphene, the synthesis of colloidal graphene via electrochemical exfoliation is time saving and easy, facile method which can be easily performed in the laboratory without any expensive and sophisticated equipment as required in other techniques. Through electrochemical exfoliation of colloidal graphene, high quality graphene can be obtained within short time. Further, after the electrochemical exfoliation of colloidal graphene, the colloidal solution is stable in the organic solvent for few weeks. The conducting electrodes prepared by this colloidal solution of graphene have wide application in the areas of flexible energy storage devices and sensors fabrication.

Polyaniline in various forms has been widely explored as an electrode material for supercapacitors due to its high theoretical charge storage capacity, facile-cost-effective synthesis, good mechanical strength and ultrafast charge transport. However, commercialization of such pristine forms is very much restricted by low solubilities, rapid agglomeration during device design accompanied by poor electrochemical life and fast environmental decomposition. The blending with nano-carbon materials, metal oxides and other competent materials, may result in high quality materials– “nanocomposites” with superior features is ideally fit for future generation energy storage devices. The present chapter deals with detailed discussions on designing, the fabrication of such binary and ternary nanocomposites, correlating their morphology with electrochemical behavior, so as to optimize their supercapacitive performances. Such an attempt would help to outline the present status and future aspects of these materials which will be of first-hand assistance especially to the beginners to this field of research.

High Ultimate Tensile Strength

Gels that are freeze-resistant and heat-resistant and have high ultimate tensile strength are desirable in practical applications owing to their potential in designing flexible energy storage devices, actuators, and sensors. Here, a simple method for fabricating ionic liquid (IL)–based click-ionogels using thiol-ene click chemistry under mild condition is reported. These click-ionogels continue to exhibit excellent mechanical properties and resilience after 10,000 fatigue cycles. Moreover, due to several unique properties of ILs, these click-ionogels exhibit high ionic conductivity, transparency, and nonflammability performance over a wide temperature range (−75° to 340°C). Click-ionogel–based triboelectric nanogenerators exhibit excellent mechanical, freeze-thaw, and heat stability. These promising features of click-ionogels will promote innovative applications in flexible and safe device design.
