“…In order to improve the EMI SE properties of conductive polymer, carbon‐based compounds are commonly employed as filler materials. [ 38–46 ] Among then, graphene (GR) is an allotrope of carbon with layered structure, which has excellent electrical and thermal conductivity. [ 47–52 ] Naeem et al researched and created a new and ecofriendly way to manufacture epoxy resin/GR nanocomposites, the conductivity of the films created by this approach reached 889 S/cm by grafting epoxy molecules onto graphene sheets.…”

Polypyrrole (PPy), an ideal organic electroactive material, shows limited application in the field of electromagnetic interference (EMI) shielding for its relatively low shielding effectiveness (SE), significant stiffness, difficult solubility, and poor processing performance. A strategy is proposed to construct three‐dimensional network structures of graphene/CNT/polypyrrole by electrochemical deposition to improve the EMI SE of polypyrrole composite films. In the graphene/CNT/polypyrrole films, the graphene/CNT substrates form the skeletons, and polypyrrole acts as bridges between graphene sheets and CNTs to form percolation networks in the multiphase and multihierarchical nanocomposites. When the deposition time increases to 80 min, the content of polypyrrole increases to 30 wt%, the conductivity improves by 27.7%, and the EMI SE improves by 11.4% at X‐band. The final film thickness is 249 μm, the conductivity is 3.06 S/mm, and the average EMI SE is 59.6 dB.

“…As a result, these polymeric entities can have their electrical conductivity fine-tuned from insulative to metal ranges via reversible and simple electrochemical or chemical doping/de-doping [4]. erefore, by simply controlling the doping level, CP electronic structure can be engineered by chemically altering new chemical structures within the molecular range through the application of chemical or electrochemical approaches, leading to the formation of a class of tunable and crucial optically, electronically, and redox/electrochemically attributable properties [5]. As a consequence, an enormous variety of stretchable, lightweight, chemically diverse, and polymeric structures with fascinating properties have been produced for a variety of extremely valuable applications.…”

Conducting polymers (CPs) have received a lot of attention because of their unique advantages over popular materials, such as universal and tunable electrical conductivity, simple invention approach, high mechanical strength, low weight, low price, and ease of processing. Polymer nanocomposites have been enthusiastically explored as superlative energy generators for low-power-consuming electronic strategies and confirmed progressive surface area, electronic conductivity, and amazing electrochemical behaviour through expanding the opportunity of utilization. The hybridization of conducting polymer with inorganic hybrid and organic nanomaterials also resulted in multifunctional hybrid nanocomposites with better capabilities in a variety of devices, including sensors, energy storage, energy harvesting, and defensive devices. The capability and assistance of modern advancements for the development of multifunctional nanomaterials/nanocomposites have been presented, as well as the approaches for producing nanostructured CPs. The mechanisms underlying their electrical conductivity, and ways for modifying their properties, are investigated. The ongoing research towards generating superior CP-based nanomaterials is also discussed. This assessment focuses on the important schemes involved in the scientific and industrial use of polymeric materials and nanocomposites intended for the scheme and manufacture of energy strategies such as solar cells, rechargeable batteries, supercapacitors, and energy cells, as well as the waiting problems and their prospects.
