The ionic medical nanometer antibacterial material that above embodiments and reference examples are prepared is tested for the property, and is surveyed
Try Escherichia coli inhibiting rate behind 50 day after tomorrow and 100 days, anti-microbial property experiment: aseptically by suitable Escherichia coli kind
(staphylococcus aureus) is moved in sterile physiological water with oese, shaken well.It is coated with nano combined sterilization material
Test plate body is put into sterilized culture dish, and the bacterium solution of 1mL debita spissitudo is coated in breadboard body surface face with rubbing method,
Sterilized agar medium is added after irradiating 1h under fluorescent light, additional amount is advisable to cover breadboard body surface face.With
After put it into incubator, and for 24 hours in 37 DEG C of constant temperature incubations, examine or check sterilizing rate using colony counting method, it is as a result as follows；
The experimental results showed that the nano anti-biotic material in chopsticks body surface of the present invention face has good antibacterial effect, material is in standard
Under test condition, embodiment 1 arrives embodiment 10, and staphylococcus aureus and Escherichia coli inhibiting rate are more than common antibacterial material
Material changes the proportion of each raw material composition in anti-biotic material respectively, has a different degrees of influence to the anti-microbial property of material, and two
Silica and MOF-SO3@MCM-22 nano material quality proportioning is 1:4, and when other ingredient dosages are fixed, antibacterial effect is best；
It is worth noting that 11 modified Nano ZY-14CMS nano powder of embodiment, antibacterial effect and antibacterial stability are significantly improved, are said
Bright modified Nano ZY-14CMS nano powder is to MOF-SO3The anti-microbial property of@MCM-22 tectum structure has preferably optimization to make
With it is long that antibacterial stablizes the time；Reference examples 1 to 2 each raw material dosage of composite brass powder of reference examples, antibacterial effect is decreased obviously, explanation
The dosage of zinc, copper and charcoal powder has an important influence on the antibiotic property of material；Reference examples 3 and reference examples 4 change composite brass powder
Still very low with the material bacteria inhibiting rate of the proportion of polybasic ion mixed solution, synthesis, anti-microbial property is bad；Reference examples 5 arrive
Reference examples 6 change MOF-SO3The raw material proportioning of@MCM-22 nano material, effect is also bad, illustrates to be hydrated zirconium oxychloride and 2-
Matching for sulfonic acid terephthalic acid (TPA) sodium raw materials compares MOF-SO3@MCM-22 nano material obtains compound have a major impact；7 He of reference examples
Reference examples 8 change SPEEK sulfonation degree and DMF additional amount, and the anti-microbial property of material is still very poor, illustrates the conjunction of SPEEK solution
At critically important；Reference examples 9 and example 10 change MOF-SO3The usage amount of@MCM-22 compound particle, antibacterial effect are substantially reduced,
Illustrate compound particle it is excessive it is very few all can the Bacteria suppression rate to material produce a very large impact；Therefore had using chopsticks body of the present invention
Excellent antibacterial effect.
