Study of Organic-Inorganic Polymer Nanocomposite Materials for Polyfunctional Resistive Sensor Devices

Abstract

The research of features of electrical conductivity of organic-inorganic polymer nanocomposite materials, filled with functionalized multiwalled carbon nanotubes depending on humidity and temperature is done using the impedance spectroscopy method. It was showed that the electrical conductivity of the probed systems in the temperature range from 280 K to 370 K increases more than 10 times. It is shown that the probed systems are perspective and can be used as thermoresistive materials for temperature sensors. It was shown, that sensor, which contains 1 % nanotubes, demonstrates the greatest speed of reacting and sensitiveness. This material is very perspective for creation of capacitance-resistance gas sensors for monitoring of environments humidity level.
