23 Jul Electrostatic spinning device for preparation of fluffy-state nanofibers and method for preparation of fluffy-state nanofibers
Abstract
The invention discloses an electrostatic spinning device for preparation of fluffy-state nanofibers and a method for preparation of fluffy-state nanofibers. The electrostatic spinning device comprisesan air supply device, an injection device and a fluffy-state fiber collection device. The air supply device is connected onto an air guide device through an air guide pipe. A stainless steel needle head of the injection device penetrates through the air guide device and extends above a receiving device. The method for preparation of fluffy-state nanofibers comprises the following steps: solutionpreparation; substrate preparation; preparation of fluffy nanofibers. The production process of the fluffy-state nanofibers comprises the following steps: performing pre-spinning in the environment without sheath gas; introducing sheath gas after a silk film appears; stopping spinning when fluffy-state fibers ascends to the top nearby in order to acquire fluffy-state nanofibers. The device is simple in technique, low in cost and higher in fluffy degree. The high porosity is used as a support of tissue engineering so that a cell-scaffold complex body is formed in vitro.
