Electrostatic spinning machine having special reticulate pattern electrode and use method thereof

Abstract

The invention relates to a high-efficiency static spinning and film-preparing device capable of controlling the orientation of nano fibers, in particular to a static spinning machine provided with a special reticulated electrode and a device for preparing a high-strength nano fiber film by application of the static spinning machine. The method changes the design concept of arranging a common metal plate or a metal roller electrode in a common static spinning device, designs the small-sized static spinning machine by utilization of the special reticulated copper electrode to be matched with a high-efficiency spiny nozzle, and prepares the high-strength nano fiber film capable of controlling the orientation of the nano fibers.

Description

technical field

[0001] The invention relates to a high-efficiency electrospinning film-making device capable of controlling the orientation of nanofibers, in particular to an electrospinning machine with special mesh electrodes and a method for preparing high-strength nanofiber films using the electrospinning machine. technical background

[0002] Electrospinning is an important method for preparing nanofibers and functional nanofiber films. At present, the research of electrospinning mainly focuses on basic research, and the simple device of single-needle nozzle and metal plate (or roller) receiving electrode is used to prepare various nanowires and nanocomposites.

[0003] The strength of nanofibers is usually high, but the strength of nanofiber membranes prepared by electrospinning is generally relatively low. The reason is that the nanofibrous membrane is formed by stacking layers of nanofibers, there is no fusion between layers, and there is not enough interpenetration...
