Abstract
The present provides an electrospinning apparatus for fabricating a nanofiber of core-shell structure, including a high-voltage electrostatic generator, a frame and a liquid brusher. A horizontally moving means is connected to the frame, and the horizontally moving means is connected with the liquid brusher. A chain-drive mechanism and a first reservoir are provided below the liquid brusher, the chain-drive mechanism includes a first sprocket and a second sprocket, and a chain is connected between the first sprocket and the second sprocket. The chain is engaged with a spray sprocket, and the spray sprocket is connected with a first motor via a revolving shaft. A core solution is contained in the first reservoir, and the lower portion of the spray sprocket is immersed in the core solution. The horizontally moving means drives the liquid brusher to move along the chain, and the liquid brusher brushes the shell solution over the chain.
