Polymer Composites for Sensor Applications

Abstract

Polymers play a major role in sensor research nowadays. Specifically, when the electrical modality of sensing is concentrated then conducting polymers is found to be highly useful. They have been explored for the development of sensors to cope with advanced modern-day requirements. There is a huge demand for sensors in detecting and assessing environmental dynamics, harmful working conditions, food poisoning, and water contaminations, and diagnostic purposes. The recent pandemic, the COVID-19 outburst all over the world, ascertained the urgency of research in the direction of designing and developing biosensors enabling distinction among the diseases and enabling medical professionals to take faster clinical decisions. The conventional approaches in environment pollutant detection techniques have no universally accepted code of conduct. Moreover, there are various experimental drawbacks of poor calibration, tedious sample preparation, blank determination, and lengthy time-consuming procedure. The composites involving conducting polymers and CNTs bring in unique multifunctional features. The motive of the present work is to review various latest developments in conducting polymer composite-based sensors.
