The present invention relates to a kind of preparation methods of highly oriented porous nano-fibre, comprise the following steps：Polylactic-co-glycolic acid is dissolved in organic solvent, to prepare polymer solution, wherein, the quality of the polylactic-co-glycolic acid and the volume ratio of organic solvent are 7% 10%；Multi-walled carbon nanotube is scattered in the polymer solution, obtains spinning solution；Air-flow air bubble spinning is carried out to spinning solution, gas flow rate is 500 1000L/min, and spinning distance is 18cm, and uses netted reception device, and single mesh size is 10cm × 2cm, obtains highly oriented porous nano-fibre.The present invention also provides a kind of highly oriented porous nano-fibres prepared using the above method.For the present invention using PLGA as spinning material, MWCNTs adds particle as nanometer, and the nano-porous fiber with high orientation and excellent mechanical performance has been prepared using air-flow air bubble spinning technique. |
