摘要：NOVELTY - Preparing highly oriented composite conductive nanofiber involves dissolving polyethylene terephthalate (PET) in a solvent to form a stable solution A, dissolving the metal salt in a solvent and ultrasonically dispersing to form a stable solution B, mixing solution A with solution B to form a homogeneous solution, stabilizing the mixed solution and adding carbon nanotube suspension to obtain precursor. USE - Method for preparing highly oriented composite conductive nanofiber (claimed). ADVANTAGE - The method enables to prepare highly oriented composite conductive nanofiber, which has high electrical conductivity while ensuring the mechanical strength of the fiber membrane, and has good industrial prospect. DETAILED DESCRIPTION - Preparing highly oriented composite conductive nanofiber involves dissolving polyethylene terephthalate (PET) in a solvent to form a stable solution A, dissolving the metal salt in a solvent and ultrasonically dispersing to form a stable solution B, mixing solution A with solution B to form a homogeneous solution, stabilizing the mixed solution and adding carbon nanotube suspension to obtain precursor. The precursor is ultrasonically dispersed for 2-24 hours to obtain the mass of the spinning solution, where the amount of metal salt, PET, solvent and carbon nanotubes in the spinning solution is 10-20%, 10-20%, 60-70% and 5-10%. The metal salt is zinc acetate or/and tetrabutyl titanate, solvent is selected from the group consisting of water, ethanol, acetic acid, phenol, trifluoroacetic acid, dichloromethane and dimethylformamide, and carbon nanotubes are carboxyl grafted multi-walled carbon nanotubes having a graft ratio of 3.84%. The prepared spinning solution is subjected to an electrospinning treatment to obtain highly oriented nanofibers and then dried in a drying oven at 20-100 degrees C, where the spinning voltage at the time of electrospinning is 10-50kv, auxiliary electrode voltage is 10-30kv, receiving distance is 10-30cm, drum speed is 200-1000 revolutions per minute (rpm) and injection rate is 0.1-10ml/hour. The prepared highly oriented nanofibers are heat-treated to obtain highly oriented composite conductive nanofibers.
