Description
Technical field
The present invention relates to material synthesis method, the preparation side of a kind of sodium alginate/polyvinyl alcohol nano
Method.
Background technology
Sodium alginate (SA) is the natural polysaccharide copolymer extracted from natural Brown algae, the polysaccharide structures of SA and human body
Extracellular matrix main polysaccharide composition Fructus Vitis viniferae ammonia glycan structures is similar, has preferable biocompatibility and no antigen.This
Outward, SA also has high-hygroscopicity, biocidal property, gel blockage and good anthemorrhagic performance, is ideal medical material.
SA spinning means in a wet process prepare, and fibre diameter is relatively thick, and the main environment extracellular base of human body cell growth
The main component proteoglycan of matter and fibrin are nanostructured.Therefore, SA nanofiber can be from structure and composition
Upper imitation extracellular matrix, beneficially cell attachment and propagation.Electrostatic spinning is method simple, that quickly prepare nanofiber.
SA solution is difficult to electrostatic spinning, it is necessary to could realize Static Spinning by the carrier polymer and intensive polar solvent being prone to Static Spinning
Silk, but intensive polar solvent such as glycerol and dimethylformamide (DMF) are the most toxic, can be to human body for medical field
Tissue and cell work the mischief.
Polyvinyl alcohol (PVA) is nontoxic, non-stimulated hydrophilic polymer, has preferable mechanical property and chemically stable
Property, it is common medical material, it is easy to prepare nanofiber by electrostatic spinning means.
Summary of the invention
The technical problem to be solved is to provide the preparation side of a kind of sodium alginate/polyvinyl alcohol nano
Method, it is provided that a kind of new synthetic method.
The synthetic method that the present invention uses, comprises the steps:
2gSA is added in 98g deionized water, under room temperature stir 2h, prepare 2%(wt, mass fraction, lower with) SA solution,
10gPVA added in 90g deionized water under conditions of 90 DEG C and stir 4h, preparing the PVA solution of 10%, by SA solution and
PVA solution mixes with the ratio of 3:8-4:8, prepares SA/PVA electrostatic spinning solution, then is 18-20kV applying voltage, accepts
Distance is 10-14cm, and under conditions of flow is 0.5-0.7mL/h, spinning obtains sodium alginate/polyvinyl alcohol nano.
The invention has the beneficial effects as follows: synthesis technique is simple, reaction condition is gentle, and production cost is relatively low, favorable repeatability,
Film hot strength is preferable.
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 pass through other
The scheme without departing from the technology of the present invention feature describe, 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.

PVA solution mixes with the ratio of 3:8, prepares SA/PVA electrostatic spinning solution, then is 16kV applying voltage, and accepting distance is 10
Cm, under conditions of flow is 0.5mL/h, spinning obtains sodium alginate/polyvinyl alcohol nano.
Embodiment 2:
2gSA is added in 98g deionized water, under room temperature stir 2h, prepare 2%(wt, mass fraction, lower with) SA solution,
10gPVA added in 90g deionized water under conditions of 90 DEG C and stir 4h, preparing the PVA solution of 10%, by SA solution and
PVA solution mixes with the ratio of 4:8, prepares SA/PVA electrostatic spinning solution, then is 20kV applying voltage, and accepting distance is 14
Cm, under conditions of flow is 0.7mL/h, spinning obtains sodium alginate/polyvinyl alcohol nano.
