Electro-spinning of highly-aligned polyacrylonitrile nano-fibres with continuous spooling

Abstract This paper reports on a new configuration for producing highly-aligned electro-spun fibres that can be produced on a static substrate or one where it is hauled off and spooled continuously to enable the production of continuous lengths. The fixture consists of a Vee-shaped polytetrafluoreth...
