Fibre-based electrochemical sensor

摘要

The present invention is related to a fibre-based electrochemical sensor for the detection of at least one chemical analyte vapour in a gaseous environment comprising at least one type of composite fibres, said type of composite fibres comprising a co-continuous phase blend with a specific association of 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.
