New Polymer Engineering Findings from Soochow University Discussed (Mechanical and Electrical Properties of the PA6/SWNTs Nanofiber Yarn by Electrospinning)

By a News Reporter-Staff News Editor at Journal of Engineering -- Investigators publish new report on Polymer Engineering. According to news originating from Suzhou, People's Republic of China, by VerticalNews correspondents, research stated, "In this article, continuous PA6/single-wall nanotubes (SWNTs) nanofiber yarns were obtained by a special electrospinning method; the mechanical and electrical properties and the electric resistance-tensile strain sensitivity of the as-spun yarns were specially studied. The main parameters in the spinning process were systematically studied."

Our news journalists obtained a quote from the research from Soochow University, "Scanning electron microscope images and mechanical tests indicated that the optimum parameters for the electrospinning process were operation voltage = 20 kV, spinning flow rate = 0.09 ml/h, and winding speed = 150 rpm. Transmission electron microscopy images showed that the SWNTs have aligned along the axis of the nanofibers and thus formed a continuous conductive network which greatly improved the electrical conductivity of the PA6 nanofiber yarn and the percolation threshold was about 0.8 wt%."

According to the news editors, the research concluded: "The electric conductivities of the yarns at different stretching ratios were also measured with a custom-made fixture attached to the high-resistance meter, and for a given carbon nanotube concentration, the conductivity changes almost linearly with the tensile strain applied on the yarns."
