<p>The present invention relates to an oil leakage sensing composition and an oil leakage sensor using the same, and more particularly, to an oil leakage sensing composition that quickly responses to a solution of petrochemicals and an oil leakage sensor using the same. According to the present invention, the oil leakage sensing composition is composed of a mixture of 75 wt% to 95 wt% of a carbon nano tube (CNT) dispersion solution and 5 wt% to 25 wt% of an alkyd resin. Also, the oil leakage senor includes: a base film layer having a tape shape; a conductive line lengthily disposed in a longitudinal direction on a top surface of the base film layer; a sensing line disposed in parallel to the conductive line on the top surface of the base film layer; and an interaction protection film layer stacked to cover the top surface of the base film layer and having sensing hole at a predetermined distance to expose the sensing line. The sensing line is composed of a mixture of 75 wt% to 95 wt% of a carbon nano tube (CNT) dispersion solution and 5 wt% to 25 wt% of an alkyd resin.</p> |
