New Trends and Challenges of Smart Sensors Based on Polymer Nanocomposites

The consistent environmental issues of population-driven intensified modern agricultural activities, urban growth, and industrialization lead to bargained environment quality because of pollution from toxic, assiduous, and bio-accumulative rising pollutants; hence it is crucial to detect them. Remarkably, electrochemical methods are appealing because of their advantages. The most recent progress in the electrochemical detection of environmental contaminations is discussed in this chapter. Polymer-based sensors are commonly utilized in environmental management because of their smart monitoring response, compact size, high sensitivity, and suitability in mild and natural conditions. Accordingly, this chapter delves into the potential of polymer nanocomposites (PNC)-based electrochemical sensor applications. It also investigates broad progress and concerns in polymer-based electrochemical sensor technology and also displayed different examples of the trendiest electrochemical sensor technologies concerning to PNC-based sensors. Furthermore, a strong emphasis has been assigned to the difficulties and developments in the current field of research.
