Selectivity enhancement of carbon nanotube composite sensor response to organic vapours by choice of the polymer matrix
Original language description
Recent literature has widely reported the utilisation of multi-walled carbon nanotubes (MWCNTs) in various sensors. Most of the applications are in the field of organic vapour sensing. Nevertheless, entangled MWCNTs structures suffer from low selectivity although their excellent sensitivity. Namely, nanotubes are a perfect nanomaterial for use as electrically conductive nanofiller, whereas the polymer matrix plays a significant role in the selectivity of sensors. The study presents a new method for measuring and sensing a volatile organic compound by a simple sensor made from a copolymer composite based on elastomeric matrix/MWCNTs.The selection of three different matrices imparts the selectivity to the sensors when reading simultaneously. Using Multiplex datalogger 34980A, the electrical resistance was measured, and data were used to select the concentration of MWCNTs in polymers to measure vapour effects.
