Description
Technical field:
The present invention relates to a kind of technical field of modification of sterilization material more particularly to a kind of fluorescence houghite sterilization materials
And preparation method thereof.
Background technique:
With the development of the social economy, the microbial contamination of environment is got worse, it has also become the significant problem that the whole world faces,
Great harm is brought to our production and life.Nano anti-biotic material is a kind of novel antibacterial material developed in recent years
Material, with the basic performance with nano material, such as skin effect, small-size effect, quantum size effect and macroscopical tunnel effect
Answer, and have the function of anti-biotic material, such as safe and efficient, wide spectrum, the property released it is good, be not likely to produce drug resistance and heat resistance
Advantage.
Anti-biotic material is broadly divided into natural, organic and inorganic three categories at present.Natural antibacterial agent is from natural animal-plant
Extract, such as chitosan and its derivative, have the characteristics that non-toxic, highly-safe, but service life is short, easily decomposes and loses
Effect.Organic antibacterial agent main component is quaternary ammonium salt, organic acid, azoles, can effectively inhibit the generation of bacterium, mould
With breeding, but be more toxic, persistence and stability it is poor.Inorganic antiseptic has silver ion, zinc ion, copper ion, titanium oxide, oxygen
Change aluminium etc., have the characteristics that less toxic antibacterial spectrum, but inorganic antiseptic has the characteristics that poor with environment, describing property of base-material, is difficult
Applied to industrial circle.
Hydrotalcite has soda acid bi-functional, the interchangeability of interlayer ion, thermal stability and memory effect, is a kind of property
It can good catalyst and catalyst carrier.
Summary of the invention:
The object of the present invention is to provide a kind of rodlike Cu2O modified europium doping zinc-aluminum gavite sterilization material and its system
Preparation Method.
Technical scheme is as follows:
A kind of rodlike Cu2O modified europium adulterates zinc-aluminum gavite sterilization material, and the sterilization material is Zn-Al-Eu-
LDHs material, Cu2O and pass through N2Secondary water be mixed with, and the ratio of three be 5mmol:(0.02g~
0.09g): (30mL~200mL).
Preferably, the Cu2O is the rodlike Cu of diameter 7-30nm2O material.
The preparation rodlike Cu2The method of O modified europium doping zinc-aluminum gavite sterilization material, including following step
It is rapid: Zn-Al-Eu-LDHs material being added in a reservoir, Cu is added2O and pass through N2Secondary water, stirring in water bath condition next time
Stream reaction, material centrifuge washing after the reaction was completed, up to rodlike Cu after drying2O modified europium doping zinc-aluminum gavite is killed
Bacterium material.
Preferably, the condition of the back flow reaction is to react 5-20 hours under 30-80 DEG C of stirring in water bath.
Preferably, the drying condition is 30-80 DEG C 3-15 hours dry.
The beneficial effects of the present invention are:
Rodlike Cu prepared by the present invention2O modified europium adulterates zinc-aluminum gavite sterilization material, due to rodlike cuprous oxide
Its order is relatively preferable, nanometer rods it is small-sized, after it is by light, after electrons and holes separation when very short
The interior hydroxyl radical free radical that can achieve surface and form strong oxidizing property, rodlike surface tension is bigger, bond distance's meeting between atom
Becoming larger, the reduction of bond energy makes it be easy to interact with extraneous molecule, and when carrying out sterilization experiment, its absorption property is more preferable,
More mushroom cells can be adsorbed, it is interior at the same time to kill more cells.Rodlike Cu2O modified europium adulterates zinc-aluminium
Houghite sterilization material, rodlike Cu in the material2Hydroxyl around O is integrated to bacterial cell wall precursors peptide with high-affinity and gathers
The alanyl-alanine of sugared end blocks the conjunction for constituting the macromolecule peptide glycan of bacteria cell wall to specifically bind with bacterium
At leading to cell wall defective and kill bacterium.So that sterilization material prepared by the present invention has more compared with conventional antimicrobial material
Excellent bactericidal effect, sterilizing rate is up to 99% or more.
