Abstract
An ultrasonic-assisted electrostatic spinning apparatus is characterized by jointly comprising a spinning machine main body, an ultrasonic vibration device, a liquid supply device, a spinning nozzle, a high-voltage wire, a high-voltage generator and a receiving device, wherein an amplitude-change pole part of the ultrasonic vibration device is extended into the spinning machine main body and is fixed on the spinning machine main body through a transducer part; the liquid supply device is connected with a liquid supply port in the lower part of the spinning machine main body through a liquid supply pipe; the spinning nozzle is connected with the spinning machine main body through a spinning port; the high-voltage wire is used for connecting the spinning nozzle with the high-voltage generator; the high-voltage generator is connected with the spinning nozzle through the high-voltage wire; the receiving device is located below the spinning nozzle. The spinning apparatus under the coupling action of ultrasonic vibration can effectively reduce viscosity of an electrostatic spinning solution and a melt, broaden electrostatic spinnable concentration range of the machine, effectively reduce diameter of fibers, reduce the structural defects of the fibers and increase the crystallization degree of the fibers, thereby achieving the purpose of improvement of mechanical performance of the electrostatic spun nano-fibers.
