23 Jul Preparation device and method for nanofiber support having three-dimensional structure
Abstract
The invention discloses a preparation device and method for a nanofiber support having a three-dimensional structure. The preparation device comprises an alternating-current high-voltage generator, a liquid supply device, an air supply device, a coaxial sprayer and a rotary receiver. The coaxial sprayer is provided with a liquid outlet and an air outlet. The air supply device is used for conveying a spinning solution or melts to the coaxial sprayer and enabling the spinning solution or melts to flow out of the liquid outlet. The air supply device can be used for generating air flow blowing from the liquid outlet to the rotary receiver via the air outlet. The alternating-current high-voltage generator forms an alternating electric field between the coaxial sprayer and the rotary receiver. The rotary receiver comprises a rotary shaft, a transmission device and support arms. A bowl-shaped revolution surface is formed when the support arms rotate with the rotary shaft. The spinning solution or melts flowing out of the liquid outlet form jet flow under effects of airflow and the alternating electric field.The preparation device and method for the nanofiber support having the three-dimensional structure have following beneficial effects: the method can be used for preparing a nanofiber three-dimensional support which is broad in material scope, tiny in fiber diameter, uniform in distribution of filament diameters, loose in structure, great in thickness and superior in mechanical properties; and the nanofiber three-dimensional support is stably in technology and good in universality and can be extensively applied to the field of tissue engineering.
