Description
Technical field
The present invention relates to a kind of electrostatic spinning apparatus of preparing nanofiber, belong to weaving and new material technology field,Specifically spray the thin liquid film of similar trumpet flower shape with a kind of bubbler, and at HV generator, electrode and reception curtainThere is multiple jets to produce and the final device that forms nanofiber mats on this liquid film top under acting in conjunction.
Background technology
Electrostatic spinning technique is that one utilizes electrostatic force to make polymer solution or melt produce jet and finally be cured as and receiveThe technology of rice fiber. The cardinal principle of this technology is drop, the fluid column that first makes polymer solution or melt composition surface curvatureFilm, bubble, crateriform protuberance etc., then utilize electrostatic force from curved surface top ejection jet. Jet is on electric field force, surfaceUnder the effects such as tension force, fly to negative plate, the refinement that is stretched during this time, solvent evaporation, jet is cured as nanofiber and is finally deposited onOn dash receiver, form nanofiber mats. The nanofiber diameter being obtained by electrostatic spinning technique is not from tens nanometer to several micronsDeng, its specific area is large, and between fiber, porosity is high, delays at textile garment, environmental project, sensor, organizational project, medicineRelease, the aspect such as energy and material and catalysis is applied widely.
Traditional electrostatic spinning apparatus adopts the pinhead-sized spinning head of syringe-like more, and therefore spinning head top formsTaylor cone be generally the droplet of 1 millimeter of diameter. Single jet is generally only sprayed on the medium and small drop of electrostatic spinning process top,Nanofiber output is lower, be about 0.01-0.3g/h (visible document " Needlelesselectrospinning:influencesoffibregeneratorgeometry》(NiuH，WangX，LinT.TheJournaloftheTextileInstitute, 103 (7), 2012,787-794.)), can not meet suitability for industrialized production and application to nanofiberDemand. Therefore, the numerous and confused development of new electrospinning process of domestic and international many researchers and enterprise and device.
At present, the electrostatic spinning apparatus of conventional improved nanofiber output comprises multiple injector electrostatic spinning device, revolvesTumbler cylinder electrostatic spinning apparatus etc. These electrospinning process and install visible document " Experimentalinvestigationsonthemulti-jetelectrospinningprocess》(A.Varesano，R.A.Carletto，andG.Mazzuchetti，，JMaterProcessTech，209(11)(2009)5178-5185)、《Needlelesselectrospinning.I.Acomparisonofcylinderanddisknozzles》(H.Niu，T.Lin，andX.Wang，，J.Appl.Polym.Sci.，114(6)(2009)3524-3530.)、" multiple spray head static spinning machine spinning state and fibre structure are arranged in parallel " (Pan Fangliang, looks into handsome punching, Pan Zhijuan, silk [J],2012 (1), 21-26.) and Chinese patent as CN200999274, CN101050550 etc., United States Patent (USP) as US1975504,US2011/0059261A1 etc., world patent WO2012/077867A1 and European patent EP 2557206 etc. These methods are still depositedAs equipment complexity, cost is high, technology is perfect not, commercially produce difficulty etc. defect.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of simple in structure, reasonable in design, cost is low and can improveThe electrostatic spinning apparatus of nanofiber output. This device comprises four of spinning system, liquid-supplying system, receiving system and transmission systemsPart composition.
