The PET/TPEE composite nanofiber membrane has the advantages that the synthesizing technology is simple, the reaction condition is mild, the production cost is low, repeatability is high, and the composite nanofiber membrane is in an amorphous state with the melting temperature and thermal stability between those of two monomers.
Description
Technical field
The present invention relates to material synthesis method, the preparation method of a kind of PET/TPEE composite nano-fiber membrane.
Background technology
Electrostatic spinning technique is to prepare submicron to one of simplest method of nanofiber, and its principle is to make high-pressure electrostatic on the solution of polymer or melt band, and when electric field force is sufficiently large, polymer drop overcomes surface tension, forms injection thread.Charged polymer drawn refinement, is deposited in base fabric formation nano fibrous membrane.Electrospun nano-fibers has purposes widely, the aspect such as including filter, catalyst, protective garment, organizational project, sensor and water process.
Polyethylene terephthalate (PET) is a kind of thermoplastic engineering plastic, has the combination properties such as high intensity, high rigidity, excellent thermostability, chemical proofing, and at electronic and electric components, be used widely in the field such as machinery, automobile component.Thermoplastic polyester elastomer (TPEE) is all thermoplastic engineering plastic, combines the elasticity of rubber and the intensity of engineering plastics and thermoplastic processing characteristics.Research finds, dichloromethane and the good solvent that mixed solvent is PET, TPEE of trifluoroacetic acid, thus, two kinds of high polymers of PET Yu TPEE are blended and carry out electrostatic spinning.
Fabric nonwoven cloth is widely used in filtration art, and according to filtration theory, under the conditions of certain bulk density, thinner fiber has higher filter efficiency.Because electrostatic spinning nano fiber has less diameter, higher porosity, relatively traditional fibre filter, there is the advantage become apparent from, can effectively cross the micron particles thing in air filtering.
Summary of the invention
The technical problem to be solved is to provide the preparation method of a kind of PET/TPEE composite nano-fiber membrane, it is provided that a kind of new synthetic method.
The synthetic method that the present invention uses, comprises the steps:
It is 25-30%(w/v% at polymer solution concentration) under conditions of, weigh PET, TPEE that mass ratio is 3.75:1-3.5:1, it is dissolved in respectively in the mixed solution of 2mL dichloromethane and 8mL trifluoroacetic acid, at room temperature, magnetic agitation 8-10h, until forming homogeneous solution, draw 5-8mL mixed solution and carry out electrostatic spinning, with PET non-woven fabrics as receiving screen, spinning voltage is 16-18kV, and syringe needle is 12-14cm away from cylinder distance, and drum rotation speed is 70-73r/min, spinning temperature is 30-32 DEG C, and humidity is ambient humidity.
The invention has the beneficial effects as follows: synthesis technique is simple, reaction condition is gentle, and production cost is relatively low, favorable repeatability, and composite nano-fiber membrane is amorphous state, and melt temperature, heat stability are between two monomers.
Detailed description of the invention
Further illustrating present disclosure below in conjunction with example, as known by the technical knowledge, the present invention also can be described by other the scheme without departing from the technology of the present invention feature, the most all within the scope of the present invention or equivalent the scope of the invention in
Change and be all included in the invention.
