Conductive Polymer/Graphene‐based Composites for Next Generation Energy Storage and Sensing Applications

Abstract

Growing environmental and health demands along with the deficiency of conventional energy sources result in the need for alternative solutions in the field of energy storage and analyte detecting systems. To address these issues, a significant increase in research interest for novel composite materials has been observed in recent years. Conductive polymers and graphene‐based composites have emerged as promising electrode materials for supercapacitors and electrochemical sensors due to their improved electrochemical properties and versatility of the synthesis methods. The synergistic effect between the composite components and the unique morphology, physical and chemical characteristics result in enhanced performance of the electrochemical devices. In this review, we discuss recent trends and achievements in the synthesis, nanoarchitecture, and application of conductive polymers and graphene‐based composites in the field of supercapacitors and electrochemical sensors. Finally, the remaining challenges and future perspectives are discussed. It is believed that this review will provide a current summary and new inspiration for groundbreaking research on advanced electrochemical devices.

Surface Properties of Graphene and Graphene Oxide Aerogels for Energy Storage Applications

“…They have great importance in our daily lives because of their distinctive characteristics, such as high porosity and lightweight, which have led to the possibility of using them in thermal insulation, packaging, and even sound insulation. However, their use is still minimal due to the large size of the pores and the low number of functional groups they have [93]. In recent studies, it was found that the addition of the polymer to the graphene aerogel significantly improves its properties [94].…”

“…[37][38][39][40][41][42]; dedicated sensors for environmental monitoring by the detection of pollutants in water, including heavy ions [43,44]; finalizing with food and drug analyses [45,46]. The second main application of the hybrid structures obtained from graphene and conducting polymers, occurring mainly in the last 10 years, is related to photovoltaic energy generation and energy storage applications/supercapacitors [47][48][49] as well as other photocatalytic applications [50].…”

Recent Progress in Polymer Waste‐Derived Porous Carbon for Supercapacitors

“…Due to the fact that electrode material determines the factors such as the specific surface area for charge storage, the pathway for charge diffusion, the conductivity of the electrode, etc., electrode material is crucial for supercapacitor performance. [42] Porous carbon materials, MOF materials, metal oxides, conductive polymers, and etc. have been applied as electrode materials.…”
