23 Jul Centrifugal electro-spinning equipment for preparing large number of three-dimensional nanofibrous scaffolds
Abstract
The invention discloses centrifugal electro-spinning equipment for preparing a large number of three-dimensional nanofibrous scaffolds. The centrifugal electro-spinning equipment comprises a high-voltage power-supply device, a centrifugal sprayer, open-type rotary-receiving devices and a centrifugal driving mechanism. The interior of the centrifugal sprayer is provided with a liquid storage cavity. Slim filament outlet pores are arranged in the centrifugal sprayer. Each open-type rotary-receiving device comprises a rotary shaft, a transmission device and multiple support arms. Bowl-shaped revolution surfaces are formed when the support arms rotate with the rotary shaft. The multiple open-type rotary-driving devices are arrayed in a ring with the centrifugal sprayer as the center. The high-voltage power-supply device is connected with the centrifugal sprayer and the open-type rotary-receiving devices and used for generating an electric field required by solution jet flow or melt jet flow. The centrifugal electro-spinning equipment for preparing a large number of three-dimensional nanofibrous scaffolds has following beneficial effects: nanofibres are formed by polymers ejected out of the electric field and centrifugal force and settled in a three-dimensional structure on the open-type rotary-receiving devices so that thickness for settlement of fibers is increased; better compatibility of biological materials is obtained; a board application range of technology materials is achieved; and scaffold structures obtained are beneficial to cell growth of the application in tissue engineering.
