Oil Leakage Sensing Composition and Oil Leakage Sensor Comprising the Same

摘要

The present invention provides an oil leakage sensing composition comprising a mixture, which rapidly reacts with leaking oil upon contact with the oil to change its electrical resistance, and an oil leakage sensor comprising an electrically conductive line formed of the composition on a base film. The oil leakage sensing composition comprises a mixture of 70-85 parts by weight of a dispersion of carbon nanotubes (CNTs), 3-15 parts by weight of an alkyd resin, and 5-15 parts by weight of silver flakes. The oil leakage sensor comprises a tape-shaped base film layer, and at least one electrically conductive line printed on the upper surface of the base film layer in the length direction, wherein the electrically conductive line is formed by applying the composition to the base film layer by a printing process.
