Реферат: The present invention is related to a method for detecting at least one chemical analyte vapour in a gaseous environment comprising the steps of: - providing a fibre-based electrochemical sensor, said fibre-based sensor comprising at least one type of composite fibres, said type of composite fibres comprising a co-continuous phase blend comprising a first and a second continuous polymer phase, the first polymer phase being sensitive to the chemical analyte vapour to be detected in use, wherein said first polymer phase comprises a dispersion of carbon nanotubes at a concentration above the percolation threshold and wherein the chemical analyte is soluble in said first polymer phase; - measuring the initial electrical conductivity of the fibre-based sensor; - bringing said fibre-based sensor into contact with at least one chemical analyte to induce a modification of the electrical conductivity of the fibres; - measuring the modification of the resulting electrical conductivity of said fibre-based sensor and correlating said modification with the identification of the chemical analyte to be detected.
