Abstract
In this paper, a carbon nanotubes (CNTs) films around microfiber gas sensor is reported. The CNTs films are deposited uniformly on the surface of microfiber with Langmuir-Blodgett(LB) coating technology. The CNTs which are rank tightly perform as cladding of microfiber and show the well absorption characteristic when they are used for gas sensing. The experimental results have shown the variations of intensity of transmitting light while the concentration of acetone and xylene around CNTs films based microfiber are different, The changes of light intensity are 3.1dB and 9.5dB respectively, when acetone and xylene concentrations reached 1200ppm. As the gas vaporizing freely, the results also show the fine characteristic with real-time response. The results demonstrate that this type of CNTs films around microfiber structure has great potential applied in trace gases detecting in micro-scale.
