Abstract
This paper has been developed and tested process of manufacturing functional nanocomposites based on epoxy resin and multi-walled carbon nanotubes (CNT) of the “Taunit-MD”. Developed a method of manufacturing small sensors based on ordered structures of nanocomposites with various mass fraction of CNTs. The results of the test sensor manufactured in change the temperature (from 27 to 90 °C) and pressure (from atmospheric to 30 bar). The coefficients of thermal- and bar-sensitivity for sensors with different orientation of the carbon nanotubes and mass content of 1, 2 and 3 %. The findings of this research shows perspective of using CNTs as conductive particles in a highly sensitive sensors of pressure and temperature.
Keywords
