Graphene‐Based Polymer Composites for High‐Performance Chemical Sensing and Detection: A Critical Review

Abstract Due to its remarkable mechanical, optical, magnetic, thermal, electrical properties, and specific surface area graphene a multifaceted substance composed of carbon atoms hybridized with sp² atoms has attracted much attention recently. Due to its many useful characteristics and morphological features, it is extensively utilized in a number of cutting‐edge technologies. A broad spectrum of biomedical sensing applications, including medication administration, kidney diseases, gas sensing, wastewater pollution monitoring, agriculture, and humidity detection are made possible by graphene and its derivatives' remarkable properties. Graphene‐based composite materials combine the strengths of their pristine components, overcoming the limitations of each on their own. More robust, lightweight, and conductive graphene‐based polymer composites can eventually replace metal and ceramics, saving money and energy and can escalate in the dynamic field of sensing. In this context, this review provides a detailed analysis regarding synthesis techniques and structural characteristics of graphene‐based polymer composites. The different applications of graphene‐based composites are also discussed in the dynamic field of sensing. This review article provides a compilation of the most recent integrated studies. Lastly, the study ends with a precise and concise conclusion further highlighting the future perspectives for upcoming research.
