Description
Technical field
The present invention relates to nano fibrous membrane, be specifically related to a kind of gelatine nano fiber film that contains nanometer silver and its production and application.
Background technology
The manufacturing of nanofiber at present one of is the focus of world attention.Nanofiber has less diameter and bigger specific surface area, therefore makes nanofiber have purposes widely.The non-woven fabrics that utilizes nanofiber to make has the feature of highly air-permeable, adds nanofiber and has big surface-area, is commonly used to make medical dressing and restores to promote wound.Nano fibrous membrane has high porosity, helps the evaporation of wound fluid, avoids the surface of a wound long-pending; And oxygen sees through easily, helps the growth and the regeneration of wound tissue cellular respiration, epithelium, accelerates the healing of wound.In addition, nanofiber also can be used to make high efficiency filtering material, protective clothing etc.
Silver has the effect of broad-spectrum antimicrobial, is a kind of natural antibacterial material, uses also relatively safety, therefore has use range widely.At present make or form the nanometer-level silver fine particle in the mode of nanotechnology, can make the activity of silver become big, antibacterial effect strengthens.With nanometer silver attached to becoming antibacterial fiber and antibiotic facing material on the fiber.Nanometer silver is compound to makes antiseptic dressing in the medical dressing, have many effects such as sterilization, anti-inflammatory, promotion wound healing.On nanofiber, adhere to nanometer silver, usually adopt the mode of dipping and coating, nanometer silver is attached on the nanofiber and forms nano silver fibre.These methods with dipping or coating are difficult to obtain the little silver-colored particle to several nanometers of diameter, and the distribution of silver-colored particle on fiber surface be difficult to reach very even, and the usage quantity of nanometer silver is increased.Adopt the method for electrostatic spinning can in nanofiber, mix nanometer silver, strengthen antibacterial effect.
Relate to the fibrous reticulum that contains nanometer silver with the method for electrostatic spinning preparation in patent CN1851087A, its method is that the nano-Ag particles uniform mixing is formed spinning solution in polypropylene solution, carries out electrostatic spinning again nano-Ag particles is mixed in the fiber.The shortcoming that contains two aspects of nano silver fibre existence that this method makes: the one, the diameter of nano-Ag particles is bigger, is 100～500 nanometers; The 2nd, nano silver powder is reunited in the mixing process of polymers soln easily, is difficult to be uniformly dispersed.
The present invention is the presoma with nanometer silver---Silver Nitrate joins and makes uniform spinning solution in the gelatin solution, by electrostatic spinning silver ions is sneaked in the fiber, and the method by photoreduction becomes nano-Ag particles with the silver ion reduction in the fiber then.The nano-Ag particles diameter can be very little like this, is low to moderate several nanometers, and nano-Ag particles can be evenly distributed in the tunica fibrosa, can utilize the antibacterial effect of nanometer silver to make products such as artificial skin, medical dressing, hemostatic material, cotton wool.
Summary of the invention
One of the technical problem to be solved in the present invention is that to overcome in the prior art nano particle bigger, nano silver powder is difficult to finely dispersed defective, provide a kind of nano-Ag particles diameter very little, nano-Ag particles can be evenly distributed in the gelatine nano fiber film that contains nanometer silver in the tunica fibrosa.The gelatine nano fiber film that contains nanometer silver provided by the invention comprises gelatine nano fiber and is evenly distributed in the nanometer silver of gelatine nano fiber, utilize this natural macromolecular material of gelatin, method by electrostatic spinning embeds nanometer silver or makes nanometer silver attached on the fiber surface in nanofiber, the gelatine nano fiber diameter is 60～200 nanometers, nano-Ag particles mean diameter 4～50nm.
Another technical problem to be solved by this invention has provided a kind of preparation method who contains the gelatine nano fiber film of nanometer silver, and this preparation method adopts electrospinning process, comprises the following steps:
(1) preparation gelatin solution: gelatin is dissolved in the formic acid, and magnetic agitation is transparent, glassy yellow liquid, i.e. gelatin-formic acid solution to dissolving fully;
(2) preparation gelatin-silver nitrate solution: in the gelatin-formic acid solution of (1) preparation, add the Silver Nitrate powder, continue to stir 1 hour, dissolve fully to Silver Nitrate;
(3) carry out electrostatic spinning in the gelatin-silver nitrate solution immigration plastics needle tubing with preparation in (2), the electrostatic spinning process condition is: static voltage is 14～32 kilovolts, and accepting distance is 6～24 centimetres, and spinning speed is 0.4 milliliter/hour, 0.7 millimeter of orifice internal diameter, spinning is at room temperature carried out;
(4) nano fibrous membrane that electrostatic spinning is made carries out photoreduction with UV-irradiation, makes the silver ions in the fiber become nano-Ag particles, and wherein the nano-Ag particles major part is distributed in the surface of fiber;
Formic acid mass concentration in the step (1) is 70%～90%; Gained gelatin-formic acid solution concentration is 14%～22% (grams per milliliter);
In the step (2) to add the Silver Nitrate powder concn be 0.3%～6%.
The nano silver fibre film of electrospinning process preparation of the present invention can make nanometer silver and nanofiber once-forming, allow nano-Ag particles attached to the nanofiber of gelatin surface or embed in the fiber and form the nano silver fibre film, can reduce coming off and agglomeration of nanometer silver effectively, avoided direct adding nano silver powder, and can reduce the silver-colored addition of making nano silver fibre, the nanometer silver of formation is distributed in tunica fibrosa more equably.
Utilize the antibacterial effect of nanometer silver, the gelatine nano fiber film that contains nanometer silver of the present invention can be applicable to make products such as artificial skin, medical dressing, hemostatic material, cotton wool.
