Nowadays, chemical sensors are attracting great interest because of their widespread applications in the industrial and environmental fields. Indeed, sensors with high sensitivity and selectivity are required for real-time detection of hazardous gas leaks. In order to detect a chemical agent, the sensing platform should be capable of detecting multiple compounds simultaneously at low concentrations without interference from background materials and with an acceptable level of false results. One potential platform for detecting a series of diverse analytes appears to be carbon nanotubes (CNTs). However, current efforts in the area of nanosensors have been concentrated on expensive single nanostructures or complex arrangements of multi-nanostructures. This has left a gap in the scientific understanding between threatening chemical agents and the sensing properties of low cost, physically modified, randomly orientiented, bulky nanotubes. The present paper investigates the bulky detection properties of low cost MWCNTs towards gas analytes. This paper will also discuss the methodology of selecting polymeric materials for tailoring their sensing properties.
