ABSTRACT
Polymers form a large class of materials that are promising for a wide variety of applications including humidity sensors. The main properties of humidity-sensitive polymers, which allow one to realize a large number of humidity sensors operating on the basis of various principles, were considered in detail in Vol. 2 of our series. Therefore, in this chapter, we focus on the issues of stability of their properties. It is stability that largely determines the possibility of using one or another polymer in the development of humidity sensors designed for the market. It is known that organic materials are by nature more susceptible to chemical degradation under the influence of oxygen or water than inorganic materials. In addition to consideration of main degradation reactions, such as thermal degradation, oxidative degradation, hydrolytic degradation, and conducting polymer dedoping, approaches to polymer stabilization are discussed as well.
