Electrical conductivity, strength and microstructure of carbon nanotube multi-yarns

摘要: Abstract Since the inception of carbon nanotubes (CNTs), there has been a great deal effort in developing CNT applications. One possible application is to utilize yarn(s) structural and electrical devices. This study investigated 13 different variations multi-yarns. The multi-yarns were evaluated compared terms tensile load behavior conductivity as well interrelationship interdependence these two properties with physical parameters micro-structural features. multi-yarn not affected by apparent diameter, number yarns, tex or density, but instead its interior compactness acid treatment. construction single yarn can be tailored achieve stress–strain ranging from stiff ductile highly non-linear behavior. single-yarn stronger stiffer than multi-yarn. decrease strength stiffness does depend directly upon yarns. Thus, larger diameter developed less no reduction comparison that array. Finally, this study’s observations provide useful information for further improvement performance yarn(s).
