Description
Technical field
The present invention relates to the applied technical field of optothermal material and biological medical polymer material, specifically a kind of base
The coating and its preparation method and application of light healing is fast implemented under near-infrared laser response.
Background technique
In recent years, magnesium-base metal is repaired due to its excellent mechanical property and the degradability in physiological environment in tissue
Concern in terms of multiple and joint, structural transplantation by more and more researchers.Magnesium alloy can overcome titanium alloy, stainless steel and cobalt
The shortcomings that alloy cannot degrade in physiological environment and must receive second operation.But magnesium metal is active metal, in vivo
Degradation speed it is too fast, cause magnesium metal to lose the mechanical property close with natural bone too early, and in degradation process, produce
Alkalization is crossed in raw hydrogen and part will affect the growth of surrounding tissue cells, influence healing process be also possible to cause inflammation or its
The symptom of his discomfort.
Prepared on magnesium alloy intelligent stimuli responsive self-healing coating be it is a kind of prevent the too fast degradation of magnesium alloy it is effective
Method.Extraneous stimulation such as pH, redox reaction and Mg2+Deng, using oversubscription sub switch, such as Subjective and Objective reciprocation,
Redox reaction etc., the nano container of stimulation encapsulation in the coating discharges anticorrosive, or promotes to be formed in coating surface
Hydroxyapatite delays corrosion process.But these stimulating courses are slow, and preparation process is more complicated, it is time-consuming
Long.
Summary of the invention
The object of the present invention is to provide coatings and its system that light healing is fast implemented under a kind of response based on near-infrared laser
Preparation Method and application, to prepare while have the coating of light healing properties, good corrosion energy.
First aspect present invention protects a kind of preparation side that light healing coating is fast implemented under responding based on near-infrared laser
Method includes the following steps:
S1, dried up using magnesium metal disk as substrate, and after ultrasound it is spare；
S2, the magnesium alloy substrate cleaned by step S1 is immersed in hydrofluoric acid, Mg alloy surface is made to form one layer of MgF2
Pretreatment coating；
S3, in the uniform three strata caprolactone of spin coating of pretreated Mg alloy surface；
S4, the magnesium alloy for handling S3 immerse in deionized water, then pyrrole monomer, nine nitric hydrates are successively added dropwise
Iron, so that Mg alloy surface forms one layer of black polypyrrole coating；
S5, the 10 strata caprolactone of Mg alloy surface spin coating handled in S4 form one layer of macromolecule with shape memory
Coating.
Preferably, in step S1, magnesium metal disk uses sand paper step by step after surface polishing as substrate；
In step S1, the successively ultrasound 20min in ethyl alcohol, acetone by substrate, then cold wind drying are spare.
Preferably, in step S2, magnesium alloy substrate is immersed in the hydrofluoric acid of wt% >=40% three days.
Preferably, in step S3, three strata caprolactone of spin coating gathers in oneself to ensure that Mg alloy surface can cover
Ester, and three layers provide pre- protective effect enough for substrate.If two layers of spin coating is less, the heavy of polypyrrole coating is easily influenced
Long-pending and uniformity；If spin coating number is excessive, coating is too thick, and preparation process is cumbersome, wastes time；
Step S3, in S5, the revolving speed of spin coating is both preferably 5000rpm 30s, and the concentration of polycaprolactone is 80mg/
ML, 5000rpm high speed spin coating 30s are the too low homogeneity for being unfavorable for film of revolving speed and film in order to guarantee that the thickness of film is uniformly unified
It can thicken, the excessively high thickness that can make film of revolving speed is thinning, to influence subsequent smooth healing time；
Pyrrole monomer in step S4, in every 1ml deionized water containing 0.02g Fe(NO3)39H2O and 3ul.Nine hydrations
Ferric nitrate makes oxidizable pyrrole be polymerized to polypyrrole as oxidant, and in ratio as shown above, the amount of Fe(NO3)39H2O is enough
So that oxidizable pyrrole is polymerized to polypyrrole, if the amount of Fe(NO3)39H2O is on the low side, is unfavorable for pyrroles's complete oxidation；If nine water
The amount for closing ferric nitrate is on the high side, and since Fe(NO3)39H2O is hydrolyzed in aqueous solution in acidity, amount excessively reinforces solution acidic, base
Bottom may be corroded, and be unfavorable for pyrroles and be deposited in substrate；
In step S4, after Fe(NO3)39H2O and pyrrole monomer is added, reaction is maintained under the conditions of 4~6 DEG C and stands 2h,
Low temperature be maintained at 4~6 DEG C be oxidizable pyrrole aggregate into polypyrrole optimum temperature and reaction speed it is fast, save experimental period, protect
Card reaction carries out at a suitable temperature；
In step S5, the thickness of 10 strata caprolactones is about 125 microns.If 9 layers of spin coating is less, illumination makes coating
The time of upper scratch healing extends, and will increase phototoxicity；If spin coating number is excessive, coating is too thick, be not suitable for investment application and
It wastes raw material, so 10 layers are optimum spin coating numbers.
Light is fast implemented under the near-infrared laser response of second aspect of the present invention protection first aspect the method preparation to be cured
The material of conjunction.
Third aspect present invention protects application of the material on magnesium alloy anticorrosion material described in second aspect.
The coating and its preparation method and application of light healing, advantage are fast implemented under a kind of response based on near-infrared laser
It is:
The good photo-thermal effect having using polypyrrole (polypyrrole, PPy) shines in 808nm near-infrared laser
Penetrate down, can be rapidly heated to required for polycaprolactone (Polycaprolactone, PCL) compared with low melting point temperature so that poly-
Caprolactone plays the characteristic of shape memory, and quick non-union defect position achievees the purpose that delay corrosion process；
The figure layer even compact of the method for the present invention preparation, there is good Corrosion Protection；And it can be applied to magnesium alloy anti-corrosion
On corrosion material；Meanwhile this method equipment investment is few, consumption resource is few, highly-safe.
