Description
Technical Field
The invention belongs to the technical field of antibacterial materials, and particularly relates to an antibacterial fabric based on a zinc oxide nano array, and a preparation method and application thereof.
Background
The living environment of human beings has a large amount of microorganisms invisible to the naked eye, including various bacteria, fungi and viruses, which can rapidly propagate under certain conditions (proper temperature, humidity and sufficient nutrients), so that the living environment of human beings brings fatal danger to human beings and causes great harm to the society. Meanwhile, through research, 80% of bacteria are transmitted through surface contact, so if some fabrics with antibacterial property can be used for manufacturing various common daily necessities such as antibacterial socks, antibacterial insoles, antibacterial cleaning towels and the like in daily life, bacteria attached to the surfaces of the articles can be killed while the articles with the antibacterial property are prevented from being polluted by the bacteria.
At present, antibacterial fabrics are researched more, and the main solution is to add an antibacterial agent with a bactericidal effect on the fabrics to realize the antibacterial property of the fabrics. Common antibacterial agents include three types of antibacterial agents, such as natural antibacterial agents, organic antibacterial agents, and inorganic antibacterial agents. Inorganic antibacterial materials are increasingly important because of their better safety and chemical stability, and their convenient use. The patent application No. CN202010496460.3 discloses a method and a device for preparing silver-plated antibacterial fabric, wherein the surface of the fabric is pretreated, and then a silver plating layer is combined with a fiber base material through plating film sputtering treatment, so that the fabric has lasting antibacterial capability. Patent application No. CN201810878958.9 mentions a reproducible antibacterial fabric with bacteria blocking capability and a green preparation process thereof, the common fabric has certain antibacterial capability through a bacteria blocking layer loaded on the surface of a base fabric layer (common fabric), the bacteria blocking layer is composed of a nanofiber membrane loaded with polyethyleneimine, the surface-loaded polyethyleneimine can enable the nanofiber membrane to have antibacterial effect through complexing copper ions with antibacterial performance, although the overall use cost of the fabric is reduced by adopting the copper ions as an antibacterial agent, the copper ions are poor in stability and easy to oxidize, and therefore the antibacterial performance of the fabric is affected. In addition, the nano zinc oxide as an inorganic antibacterial material is a traditional antibacterial material, has been widely used in the past years due to safety and stability, excellent antibacterial performance and low cost. The sterilization mechanism of the nano zinc oxide is the interaction between ROS generated in the photocatalysis process and bacteria, so that the antibacterial performance of the nano zinc oxide can be influenced in dark and lightless environments.
Therefore, it is still necessary to develop a fabric having both "prevention" and "killing" effects by a simple process.
Disclosure of Invention
In order to solve the technical problems, the invention provides an antibacterial fabric based on a zinc oxide nano-array, and a preparation method and application thereof.
The invention is realized by the following technical scheme.
The invention aims to provide a preparation method of an antibacterial fabric based on a zinc oxide nano-array, which comprises the following steps:
s1, mixing zinc chloride and water to obtain a solution A; adding ammonia water into the solution A to obtain a solution B;
s2, growing a layer of nano zinc oxide on the surface of the fabric through a magnetron sputtering coating instrument to obtain a modified fabric with a zinc oxide seed crystal layer;
and S3, adding the fabric modified by the S2 into the solution B for hydrothermal reaction, and after the reaction is finished, sequentially washing and drying to obtain the antibacterial fabric based on the zinc oxide nano-array.
Preferably, in S1, the ratio of the zinc chloride to the water is 1.8-2.0 g: 100 ml.
Preferably, in S1, the volume ratio of the ammonia water to the solution a is 2-3: 50.
preferably, in S2, the zinc oxide seed layer is grown by magnetron sputtering under a growth pressure of 1.5 to 2.5Pa, a growth time of 10 to 20min, an output of 50 to 70W, and an oxygen and argon flow rate of 10%.
Preferably, in S2, the zinc oxide seed layer has a thickness of 30 nm.
Preferably, in S3, the temperature during the hydrothermal reaction is 80-100 ℃, and the reaction time is 100-140 min.
The second purpose of the invention is to provide the zinc oxide nano-array-based antibacterial fabric prepared by the preparation method.
Preferably, an array structure formed by zinc oxide nanowires is uniformly grown on the antibacterial fabric, and the zinc oxide nanowires are 1 μm in length and 50nm in diameter.
The third purpose of the invention is to provide the application of the antibacterial fabric based on the zinc oxide nano-array in the preparation of antibacterial articles.
Compared with the prior art, the invention has the following beneficial effects:
the invention grows the zinc oxide nano-array on the fabric through the magnetron sputtering coating instrument and the hydrothermal reaction, the preparation method is simple, and the fabric has the antibacterial function, and the antibacterial way is divided into two aspects: on the one hand, nanometer zinc oxide itself has bactericidal performance, and on the other hand, the zinc oxide nanowire array structure that distributes on the fabric, after the bacterium contacts with this structure, through the membrane interact between bacterium and array or the physics fabric of buckling for array structure destroys bacterium structural integrity, thereby plays the physical bactericidal effect, and this bactericidal mechanism is different with traditional bactericidal mechanism, has avoided the problem that antibacterial property receives the influence under dark light environment. The invention provides a method for constructing zinc oxide nano arrays on various fabrics, so that an antibacterial fabric based on a physical bactericidal effect is obtained, and various articles prepared on the basis of the antibacterial fabric can realize double effects of prevention and killing when facing bacteria.

Detailed Description
In order to make the technical solutions of the present invention better understood and implemented by those skilled in the art, the present invention is further described below with reference to the following specific embodiments and the accompanying drawings, but the embodiments are not meant to limit the present invention.
The experimental methods and the detection methods described in the following examples are all conventional methods unless otherwise specified; the reagents and materials are commercially available, unless otherwise specified.
Example 1
The embodiment is used for preparing an antibacterial carbon fiber fabric based on a zinc oxide nano array, and as shown in fig. 1, the preparation method comprises the following steps:
1) mixing 1.39g of zinc chloride solution with 100ml of water solution to obtain solution A;
2) dropwise adding 5ml of ammonia water into the solution A, and stirring for 5min to obtain a solution B;
3) setting the growth pressure to be 2Pa, the output power to be 60W, the argon and oxygen flow meter to be 10 percent and the growth time to be 15min by a magnetron sputtering coating instrument, and obtaining a zinc oxide crystal seed layer with the thickness of 30nm on the surface of the carbon fiber fabric;
4) and (2) inverting the carbon fiber fabric with the zinc oxide seed crystal layer on the surface in the solution B to perform hydrothermal reaction under the reaction condition of 90 DEG/120 min, taking out the carbon fiber fabric after the reaction is finished, cleaning impurities adhered to the surface of the carbon fiber fabric by using an aqueous solution, then putting the carbon fiber fabric into a 60-DEG drying oven to dry for 4h, and obtaining the antibacterial carbon fiber fabric with the zinc oxide nano-array on the surface after the drying is finished.
The surface morphology of the antibacterial carbon fiber fabric having a zinc oxide nano array on the surface prepared in example 1 was observed by a scanning electron microscope, and the result is shown in fig. 2.
As can be seen from FIG. 2, under different multiplying powers, it is shown that dense zinc oxide nano-arrays grow on the surface of the carbon fiber fabric, the diameter of the zinc oxide nano-wires is about 50nm, and the length is about 1 μm.
In this example, an X-ray diffractometer was used to identify the crystal form of the antibacterial carbon fiber fabric with zinc oxide nano-arrays on the surface prepared in example 1, and the results are shown in fig. 3, comparing with the carbon fiber fabric and the carbon fiber fabric with zinc oxide seed layers on the surface prepared in step 3) of example 1.
As can be seen from fig. 3, the carbon fiber fabric has two distinct diffraction peaks. Meanwhile, a corresponding zinc oxide diffraction peak can be clearly seen on the carbon fiber fabric with the zinc oxide nano array, and in addition, no obvious zinc oxide diffraction peak exists because a zinc oxide crystal seed layer on the surface of the carbon fiber fabric does not form a crystalline state.
In this example, two different antibacterial methods were used to test the antibacterial performance of the carbon fiber fabric with a zinc oxide nano-array on the surface prepared in example 1.
The method comprises the following steps:
attaching antibacterial carbon fiber fabric to the inner wall of a beaker, wherein the beaker contains a certain amount of gram-positive bacteria-staphylococcus aureus (ATCC 6538) bacterial liquid, applying a certain rotating speed to enable the bacterial liquid and the antibacterial fabric to interact, and after 80min, under the rotating speeds of 200r/min, 400r/min and 800r/min, the bacterial quantity is 10 at the beginning8cfu/ml is reduced to 106The sterilization rate was 99% in cfu/ml, and as shown in FIG. 4(a), the sterilization rate was changed with rotation in the same period of timeThe sterilizing rate is increased gradually.
The method 2 comprises the following steps:
dripping 10 on the surface of the antibacterial carbon fiber fabric8cfu/ml of gram-positive bacteria, namely staphylococcus aureus (ATCC 6538) and gram-negative bacteria, namely escherichia coli (ATCC 25312), are slightly bent to enable the surface bacteria to interact, as shown in a scanning electron microscope image of bacteria shown in figure 4(b), bacterial cells of both staphylococcus aureus and escherichia coli are in an intact state under the condition of no bending, and after 300 times of bending, the bacteria are seriously damaged due to physical interaction with the zinc oxide nanowire array and are in a dead state. The scanning electron microscope image of the bacteria can show that the carbon fiber fabric has better antibacterial performance.
