Abstract

This study aims to investigate advance material and develops a technique that detects the smallest traces of hazard gases for the instantaneous rate of atmospheric corrosion of archaeological materials indoor and outdoor. This article describes the advance and use of multiple-walled carbon nanotubes (MWCNT) with carbon nanoparticles and spheres as a network to investigate it as resistive gas nanosensors for SO2 detection. The responses of the sensors based on the MWCNs in various concentration to SO2 responses, in SO2 ambient air, performed by resistance measurements from room temperatures of 25 °C to 250 °C, more than 400 °C the structure will. SO2 gas concentration from 0.5 to 20 ppm to find new application, particularly application in Museums to conserve cultural heritage materials from deterioration caused by hazard gases.
