“…Electrical conductivity enables materials to be utilized in electronic devices or as conducting membranes for sensor application 124,125 . The electrical conductivity of PPy is influenced by several crucial factors, such as type of oxidants, initial O/M, dopants or surfactants, polymerization temperature, and polymerization time 126‐128 .…”

Polypyrrole (PPy) has unique features such as easy synthesis, environmental stability, and high electrical conductivity (approximately 105 S/cm and even >380 S/cm) for bulk and thin‐film materials. Thus, PPy is applied in numerous well‐established applications, such as in sensors, supercapacitors, and resonators. These applications take advantage of the unique properties achieved through the structure and properties of PPy. This article comprehensively elaborates the methods used to synthesize conductive PPy, along with the important factors affecting its conductivity. Emphasis is given to versatile and basic approaches that enable control of the microstructural features that eventually determine PPy conductivity. Despite the intensive research in this area, no previous study has presented all possible relevant information about PPy fabrication and the important factors influencing its electrical conductivity.

“…Improved flexural properties for composites loading are ascribed to high stiffness and aspect ratio of graphene sheets. 28 In addition, increment in flexural properties was anticipated as a result of enhanced adhesion between components in the composites. A study has reported that the modulus of nanocomposites at elevated GNP loading may not increase due to agglomeration of GNP sheets.…”

Exfoliated graphene nanoplatelets (3 phr) were incorporated into polypropylene with increasing concentration of treated and untreated kenaf flour 0, 10, 20, 30, and 40 wt%, respectively, and prepared via melt-extrusion using corotating twin screw extruder. The resulting nanocomposites were characterized in terms of electrical, thermomechanical, thermal conductivity, thermal behavior, heat deflection temperature (HDT), and mechanical, morphological, and structural properties. Fourier transform infrared spectroscopic results demonstrate that the fibers interacted with the matrix and affected the mechanical behavior. The effective thermal conductivities decreased with increasing fiber content, while HDT of the nanocomposites was found to significantly increase, respectively. The electrical properties decreased with increasing fiber content. However, despite the decline in electrical conductivity, the composites were still relatively conductive for applications such as sensors and electromagnetic shielding after fiber inclusion.

In recent years, numerous discoveries and investigations have been remarked for the development of carbon-based polymer nanocomposites. Carbon-based materials and their composites hold encouraging employment in a broad array of fields, for example, energy storage devices, fuel cells, membranes sensors, actuators, and electromagnetic shielding. Carbon and its derivatives exhibit some remarkable features such as high conductivity, high surface area, excellent chemical endurance, and good mechanical durability. On the other hand, characteristics such as docility, lower price, and high environmental resistance are some of the unique properties of conducting polymers (CPs). To enhance the properties and performance, polymeric electrode materials can be modified suitably by metal oxides and carbon materials resulting in a composite that helps in the collection and accumulation of charges due to large surface area. The carbon-polymer nanocomposites assist in overcoming the difficulties arising in achieving the high performance of polymeric compounds and deliver high-performance composites that can be used in electrochemical energy storage devices. Carbon-based polymer nanocomposites have both advantages and disadvantages, so in this review, attempts are made to understand their synergistic behavior and resulting performance. The three electrochemical energy storage systems and the type of electrode materials used for them have been studied here in this article and some aspects for example morphology, exterior area, temperature, and approaches have been observed to influence the activity of electrochemical methods. This review article evaluates and compiles reported data to present a significant and extensive summary of the state of the art.
