NONWOVEN-BASED CHEMI-CAPACITIVE OR CHEMI-RESISTIVE GAS SENSOR |
摘要 |
A chemical gas sensor formed from a nonwoven material is described. The gas sensor includes a flexible, gas-permeable, nonwoven web-based material substrate having a matrix that is composed of a plurality of inert thermoplastic, pulp, cellulose or staple fibers as either a major or minor portion, with a plurality of gas-sensitive fibers formed from a polymer that can absorb volatile organic compounds (VOC), and a plurality of electrically conductive fibers. The gas-sensitive fibers are intermixed with and associated spatially among a network of adjacent electrically conductive fibers, such that a change in physical morphology of said gas-sensitive fibers as a result of interacting with volatile organic compounds, causes a change in dielectric properties that disrupts said network of adjacent electrically conductive fibers. The sensor can be configured as either a resistive or a capacitive chemisensor. |
