Novel Carbon Nanotube-Based Non-Woven Composite Sensors: Processing, Characterization and Potential Applications

摘要: Carbon nanotube-based composites have exhibited tremendous potential for a variety of multifunctional applications. Recent advances in processing carbon allowed the formation conductive networks on surfaces wide range fibers. In this research, nanotubes (CNTs) are selectively deposited onto randomly oriented, non-woven aramid fabric using dipcoating process as well an innovative electrophoretic deposition process. The these electrically enable nanotube based nanocomposites to be used sensors. exhibit piezoresistivity, that is, resistance changes lot more than standard change due deformation. This unusually large is because nanotube-nanotube tunneling effect. These sensors then characterized under different loading conditions and optimized improved sensitivity. novel approach utilizing fibers backbone piezoresistive network enables broad application flexibility integrating into strain damage detection capabilities. Opportunities future structural health monitoring will discussed.
