6. Electrospinning Fibrous Material
Electrospinning is one of the most important methods to prepare nanofibers. It has the advantages of wide range of spinnable materials, adjustable structure and extensive preparation technology.By choosing different spinning raw material, with a wide variety of nanofibers can be prepared, including organic nanofibers (natural polymer fibers, synthetic polymer nanofibers) and inorganic nanofibers (oxide nanofibers, carbon nanofibers, metal fiber, carbide and nitride nanofibers, etc.) and inorganic/organic composite nanofibers (oxide/polymer composite, metal/polymer composite and metal sulfide/polymer composite and carbon materials/polymer composite).
(1) Natural polymer nanofibers: cellulose, sodium alginate, chitosan, hyaluronic acid, gelatin, collagen, silk fibroin, natural rubber, etc.
(3) Synthetic polymer nanofibers: PVA, PEO, PAA, PVP, PAN, PA, PVC, PVDF, PS, PMMA, PCL, PLGA, etc.
Inorganic nanofibers: the preparation of inorganic nanofibers by electrospinning is generally divided into three processes:
1) Prepare spinnable precursor solution;
2) Inorganic/polymer hybrid nanofibers were obtained by electrospinning.
3) Remove organic components by calcining.Titanium dioxide, zinc oxide, tin oxide, silicon oxide, iron and carbon nanofibers can be prepared.
Inorganic/organic composite nanofibers: the preparation methods of composite nanofibers by electrospinning technology mainly include the following four methods:
A. Dispersed mixed electrospinning.The inorganic nanomaterials were directly dispersed into polymer solution and mixed to conduct electrospinning.
B. Sol-gel electrospinning.The precursor solution of inorganic nanomaterials is mixed with polymer solution for electrospinning.
C. Preparation of inorganic nanomaterials in the original position of polymer solution for electrospinning.
D. Post-treatment of electrospinning fiber.Such as ultraviolet reduction, liquid phase deposition, atomic layer deposition, gas-solid heterogeneous reaction, etc.TiO2/PVP, SiO2/PVA, Ag/PAN, Zns/PPV, graphene /PVAc, hydroxyapatite /PLA and other inorganic/organic composite nanofibers can be prepared.
