Abstract

The invention discloses a tip-induced electrostatic spinning nozzle which comprises a nozzle body, a spinning needle and an airflow assisted nozzle. A liquid cavity and an air cavity are formed in thenozzle body, a liquid inlet, a liquid outlet, an air inlet and an air outlet are formed in the nozzle body, the liquid inlet and the liquid outlet are communicated with the liquid cavity, and the airinlet and the air outlet are communicated with the air cavity. The airflow assisted nozzle is fixedly arranged at the air outlet and communicated with the air cavity; the spinning needle is fixedly arranged at the liquid outlet and communicated with the liquid cavity; a free end of the spinning needle penetrates the air cavity and extends out of the airflow assisted nozzle; a conductive needle isarranged in the spinning needle. Besides, the invention further discloses a tip-induced electrostatic spinning device. The large-diameter spinning needle can be used without greatly increasing operating voltage, the production efficiency of nanofibers can be improved, and the tip-induced electrostatic spinning nozzle is good in spinning quality and high in safety.

Description

technical field [0001] The invention relates to the technical field of electrospinning, in particular to a needle-point-induced electrostatic spinning nozzle and a needle-point-induced electrostatic spinning device. Background technique [0002] Electrospinning technology is a special process for preparing nanofibers by using electric field force and solution viscous force to stretch the solution. Among them, the range of solutions suitable for electrospinning is extremely wide, and nanofibers can be prepared by electrospinning technology from polymer solutions to metal solutions. Utilizing the advantages of high specific surface area and high porosity of nanofibers, it can be applied to corresponding fields, including wire printing in the field of microelectronics technology, catalytic applications in the chemical industry, tissue engineering in biomedicine, filtration and water purification, etc. [0003] The traditional electrospinning method mainly uses a nozzle with a ...
