Abstract

Polymer nanocomposites (PNCs) are specific materials in which the polymer serves as matrix and the other materials in nano scale are fillers. Polymers are active ingredients in sensor technology, and several medical and electronic equipments are based on these materials. They are used in real-time analysis of biological and environmental samples. The properties of a polymer itself are interesting, but the filler normally has a very prominent role in engineering these properties. The matrix and filler make a hybrid material, and their biomedical applications range from tissue engineering to bone reconstruction. Energy storage devices, energy harvesting devices, and corrosion protection. This chapter covers sensing applications of PNCs for selected chemicals in the field of environmental chemistry, medical, and several other industries. Sensors for some of the chemicals containing criterion air pollutants (CAP) are described in this chapter. Besides CAPs, sensors for selected notorious volatile organic and inorganic pollutants are outlined. The chapter provides important insights about sensing technology, two tables that summarize the properties of materials are given, and also necessary mechanism of action is explained for several sensing materials.
