title = "SWCNT thin film enabled piezoresistive sensors - Fabrication, characterization and application for structural health monitoring for polymeric composites structure",
abstract = "With the quantitative carbon nanotube dispersion characterization methods (preparative ultracentrifuge method (PUM) and dynamic light scattering (DLS)) and the spray-coating technique, the processingstructure-property relationships of single-wall carbon nanotube (SWCNT) thin film piezoresistive sensors were studied. It was found that the gauge factor of the sensors for a small tensile deformation (less than 2\% strain) is close to unity and showed negligible dependence on the film thickness and SWCNT bundle length (L) and diameter (d). With incorporation of a small amount of conducting polymer - poly (3, 4- ethylenedioxythiophene)-poly (styrenesulfonate) (PEDOT: PSS) into SWCNT network, the SWCNT/PEDOT: PSS hybrid thin film sensor showed significantly improved gauge factor and electrical conductivity. The spray coating technique was further developed into a roll-to-roll process for continuously fabricating SWCNT thin film enabled fiber sensors. A promising application of the fiber sensor for real-time monitoring the curing process of epoxy resin has been demonstrated.",
