Abstract

The invention discloses a linear melt electrospinning device uniform in network formation and an application method thereof. The linear melt electrospinning device mainly comprises a base, a tractionbelt, a guide rail, a spinning line, a receiver, a polymer storage device, a heating temperature control system and the like. The guide rail, a stepping motor and a supporting column are fixed on thebase. The polymer storage device bestrides on the guide rail, bottom studs at one side of the polymer storage device are fixed together with the traction belt, and the traction belt is connected withthe stepping motor, so that the polymer storage device does reciprocating motion on the guide rail. The outer surface of the spinning line is grounded, the interior of the spinning line is connected with a heating system, and the spinning line passes through the polymer storage device to be in close contact with materials. The receiver is connected with a high voltage electrostatic generator and used for receiving fibers. The linear melt electrospinning device has the advantages that a high temperature metal wire is utilized and is in the close contact with a reciprocating solid-state polymer,so that the polymer is melted and adhered on the surface of the metal wire, uniform distribution of an electric field is guaranteed, microscopic uniform distribution of a Taylor cone and macroscopicuniform network formation are realized, the performance of melt electrospun nanofibers is improved, and the application fields of the linear melt electrospinning device are broadened.

Description

technical field [0001] The invention relates to a linear melt electrospinning device and method with uniform netting, belonging to the field of electrospinning. Background technique [0002] Melt electrospinning is that the polymer melt forms a Taylor cone under the action of a high-voltage electrostatic field, and then is stretched to the receiving device. During the stretching process, the melt solidifies, and finally forms a micron-sized, sub- Micron-scale or even nano-scale fibers, its products can be widely used in micro-nano filtration, lithium battery separator, biomedicine and other fields. Compared with solution electrospinning, melt electrospinning has the advantages of low production cost, high production efficiency, green, non-toxic and non-polluting, and small-scale industrial products are now available. [0003] For melt-spun fiber membrane products, the uniformity of its microstructure has a significant impact on product performance. Existing large-scale mel...
