Polymer/Carbon Composites for Sensing

Abstract

It is indisputable that sensors are indispensable in our daily life. In parallel to the research in the field of organic electronics, there is a serious effort to develop technologically compatible sensors based on polymers. Due to the widespread usage of microelectronics, it is quite natural that the main effort is focused on the development of sensors providing electrical output. But until the discovery of conducting polymers, it was necessary to find a way how to increase the basic electrical conductivity of the polymers, which had been considered to be perfect insulators. The easiest way to do it is to add and disperse in a polymer a small amount of conducting or semiconducting material with particles on the micro- or sub-micrometer scale, for example, carbon fibers or carbon black. A proper concentration of the “filler” is around the percolation threshold, at which the sensor’s sensitivity reaches the maximum. The details are described in Sect. 2.
