Materials Science & Engineering B, 2022

Advances in conducting polymer-based nanocomposites (CPNCs) as sensing materials offer unique prospects to apprehend previously inaccessible sensing properties and applications. In this review article, the synthesis and properties of CPNCs are highlighted as pioneer transducers for designing advanced sensing devices. Synthetic strategies of CPNC are also discussed in the brief and classified into ex-situ and in-situ categories employing (1) chemical; (2) electrochemical; (3) photochemical; and (4) hybrid approach. The composite structure of conducting polymers (CPs), with inorganic and organic compounds, has enhanced surface adsorption, responsiveness, catalytic, and/or electron transport behavior for sensing applications. Thus, CPNCs are explored to sense atmospheric gases, humidity, explosives, water pollutants, and food adulterants. The literature reveals that sensor technology has been effectively improved in terms of sensitivity and selectivity due to progress in CPNCs. However, there are still several technical challenges that need to be solved for CPNCs based sensor technology. Herein, the key issues regarding the use of CPNC based materials in the development of state-of-the-art sensors are discussed. Furthermore, a perspective on the next-generation sensor technology concerning materials has been demonstrated with exclusive examples of conducting polymers based nano composite.
