Embodiment 10:
A kind of preparation method of multifunctional antibiotic film, is comprised the following steps that:
(1)Silverskin is plated, using magnetron sputtering plating mode, silverskin 200nm is plated on matrix, process conditions are as follows:Using Φ
60mm, the silver-colored target that thickness is 5mm.Target spacing is adjusted to 60mm, power 120W, DC mode sputtering.
(2)Spray TiO2, nano particle TiO is sprayed using injecting type air gun2To Ag films surface.
(3)Poly tetrafluoroethylene is plated, using PECVD plated film modes, is being loaded with nano particle TiO2200 are grown on silverskin
The polytetrafluoroethylene (PTFE) of nm thickness.In cavity, C is passed through4F8Gas, process conditions are as follows:Sample stage is highly adjusted to 35mm, gas
Press 18Pa, power 100W.Plated film speed can reach 20nm/min.
(4)Nano impression, polytetrafluoroethylene (PTFE) is heated into 200 DEG C of progress vitrifying processing first, then in design size(Circle
Post punch-pin is highly 180nm, and body diameter is Φ 200nm)Mould under carry out impressing processing.
Produce, thickness is the Antibiotic Membrane that 400nm carries groove structure.
Antagonistic property can be evaluated using the absorbance of bacterial concentration, briefly, for bacterium solution, if the concentration of bacterium is high
If, absorbance is just high.Sample causes the concentration step-down of bacterium solution, and bacterial concentration is more few better, and sample just has bacteriostasis property.
The height of microorganism concn is characterized using staphylococcus aureus culture medium turbidity height.Using control sample and reality
The bacteriostatic film sample of the preparation of example 3 is applied, carries out the antibacterial tests of Antibiotic Membrane, the anti-bacterial result is as follows:It is from fig. 6, it can be seen that right
More poor than sample antibiotic property, light absorption value is bigger than normal, and light absorption value keeps high stable state substantially;Bacteriostatic film prepared by embodiment 3 exists
Within one week, good inhibition is kept to staphylococcus aureus always.
Above-mentioned control sample is existing composite disinfecting film.
Above-described is only the preferred embodiment of the present invention, it is noted that for those skilled in the art,
Under the premise of general idea of the present invention is not departed from, some changes and improvements can also be made, these should also be considered as the present invention's
Protection domain.
