Abstract
A novel electrostatic spinning collector comprises a spinning jet connected with a reservoir and a collector body. The collector body is a rotary barrel or a fence-shaped rotary barrel. The collector body can be a cylinder, a sphere with two symmetrical end openings, or an ellipsoid. The spinning jet and the collector body are disposed on an insulation support. An axial line of the spinning jet coincides with that of the collector body, the head of the spinning jet is extended into the collector body so that a strong electrostatic field between the spinning jet and the collector is sealed in the barrel. Field strength is evenly distributed 360 degrees along a vertical axial line. The collector can be placed horizontally and vertically to place the collector on the insulation support. When the collector is placed vertically, drops of precursor solution do not fall on spun nanofiber membranes during fast spinning, and production efficiency is improved.
Description
Technical field
The present invention relates to a kind of novel electrostatic spinning gatherer.
Background technology
Electrostatic spinning plays an increasingly important role in fields such as bio-medical material, catalysis, filtration, photoelectricity, the energy as the technology of a kind of simple and efficient ground preparation superfine nano fiber.The nanofiber that how to prepare characteristics such as having excellent optics, electricity, mechanics has become the hot issue of electrostatic spinning research field.Gatherer is the important component part of electrospinning device, and the shape of gatherer, structure and placement location have determined efficient, structure, performance and the distribution of institute's spinning nano fibre.At present, the gatherer that is applied to electrospinning device has a lot, such as: drum-type gatherer, disc type gatherer, static state (dynamically) water-bath type gatherer, and flat gatherer etc.Yet the position relation between these gatherers and the spinning head all has a common ground, and promptly shower nozzle is positioned at a side or the outside of gathering-device, and keeps certain distance with gatherer.Limitation below this configuration mode exists: the first, in the electrostatic spinning implementation process, can only collect nano fibrous membrane in one direction, and tunica fibrosa exists area little, shortcoming such as thickness is irregular is unfavorable for preparing the nano fibrous membrane of large-area uniformity; The second, because institute's making alive is very high between shower nozzle and the gatherer, usually between several kilovolts to tens kilovolts, and be exposed to open space fully, this has brought very big potential safety hazard to actual mechanical process.
Summary of the invention
The objective of the invention is provides a kind of novel electrostatic spinning gatherer to above-mentioned technical problem.
The objective of the invention is to realize through following technical scheme:
A kind of novel electrostatic spinning gatherer; Comprise the spinning head and the gatherer body that link to each other with reservoir; Said gatherer body is single-revolution cylindrical shell or paliform rotating cylinder, can be spheroidal or elliposoidal cylindrical, the two ends symmetrical openings, and said spinning head that links to each other with reservoir and said gatherer body all are placed on the insulating support platform; The axial line of spinning head overlaps with the axial line of gatherer body; And make spinning head put in the inside of gatherer body, and guaranteeing that the strong electrostatic field between spinning head and the gatherer is enclosed in the tube, electric-field intensity is evenly distributed in vertical central lines 360 degree directions.
Said gatherer body according to different needs, may be selected to be rotating cylinder or paliform rotating cylinder, and the nano fibrous membrane effect that it obtains also will be different.
The said spinning head that links to each other with reservoir according to actual needs, can move at the direction of axis line of gatherer body.
The measuring pump that said reservoir and configures flow is connected.
The inner wall surface of said gatherer body can (according to actual needs) with the layer of metal paper tinsel, for example aluminium foil, Copper Foil, thus on metal forming, collect nano fibrous membrane.
After add positive voltage to spinning head, gatherer added negative voltage, the electric field between spinning head and the gatherer will be enclosed in the tube, and formed electric-field intensity is evenly distributed on vertical central lines 360 degree directions between spinning head and the gatherer.When precursor solution after the spinning head place forms taylor cone, under the electrostatic field force effect, spray many jets, stretched, solvent evaporates, solidification process finally are deposited on the inner surface of gatherer, form the uniform nano fibrous membrane of a layer thickness.
The gatherer of this patent design is except horizontal positioned; Can also vertically place, gatherer is placed on the insulating support platform, the advantage of vertically placing is to spray at a high speed in the silk process; The drop of precursor solution will can not be dropped on the nano fibrous membrane that has spun, help enhancing productivity.
The said spinning head that links to each other with reservoir must be inner at gatherer, guarantees that strong electrostatic field is enclosed in the tube, and can deposit uniform nano fibrous membrane along inner collector wall;
The said spinning head that links to each other with reservoir is placed on the axial line of gatherer, guarantees that electric-field intensity is evenly distributed in vertical central lines 360 degree directions.
In the electrostatic spinning process, the space of not only collecting nano fibrous membrane is expanded, and the strong electrostatic field between spinning head and the gatherer is shielded in the tube, effectively reduces the potential safety hazard that high pressure brings.
