A low temperature operated NO2 gas POF sensor based on conducting graft polymer

Abstract

A simple POF sensor has been developed, which is used to detect and measure the concentration of nitrogen dioxide, at low temperatures (about 50°C). In this work, we present a thermal profiling process of the sensor head type POF, and the application of a sensing structure based on grafted polymer preparation by a dip-coating technique. We made characterization prepared structures and tests with various NO2 concentrations at low temperature and dry atmosphere.
