Try Escherichia coli inhibiting rate behind 50 day after tomorrow and 100 days, anti-microbial property experiment：Aseptically by appropriate Escherichia coli kind
（Staphylococcus aureus）Moved to oese in sterile physiological water, shaken well.It is coated with nano combined sterilization material
Experiment plate body is put into sterilized culture dish, and the bacterium solution of 1mL debita spissitudos is coated in into breadboard body surface face with rubbing method,
Sterilized agar medium is added after irradiating 1h under fluorescent light, addition is advisable to cover breadboard body surface face.With
After put it into incubator, and in 37 DEG C of incubated 24h, sterilizing rate is examined or check using colony counting method, it is as a result as follows；
Test result indicates that the nano anti-biotic material in chopsticks body surface face of the present invention has good antibacterial effect, material is surveyed in standard
Under the conditions of examination, embodiment 1 arrives embodiment 10, and staphylococcus aureus and Escherichia coli inhibiting rate exceed common anti-biotic material,
Change the proportioning of each raw material composition in anti-biotic material respectively, have different degrees of influence, dioxy to the anti-microbial property of material
SiClx and MOF-SO3@MCM-22 nano materials quality proportioning is 1：4, when other dispensing dosages are fixed, antibacterial effect is best；Value
It is to be noted that the modified Nano ZY-14CMS nano powders of embodiment 11, antibacterial effect and antibacterial stability significantly improve, explanation
Modified Nano ZY-14CMS nano powders are to MOF-SO3The anti-microbial property of@MCM-22 tectum structures has more preferable optimization function,
Antibacterial stabilization time is grown；Reference examples 1 to each raw material dosage of composite brass powder of reference examples 2, antibacterial effect is decreased obviously, illustrate zinc,
The dosage of copper and charcoal powder produces material impact to the antibiotic property of material；Reference examples 3 and reference examples 4, change composite brass powder and
The proportioning of polybasic ion mixed solution, the material bacteria inhibiting rate of synthesis is still very low, and anti-microbial property is bad；Reference examples 5 to pair
6 change MOF-SO as usual3The raw material proportioning of@MCM-22 nano materials, effect is also bad, illustrates to be hydrated zirconium oxychloride and 2-sulphur
Matching somebody with somebody for sour terephthalic acid (TPA) sodium raw materials compares MOF-SO3@MCM-22 nano materials obtain compound have a major impact；Reference examples 7 and right
As usual 8, change SPEEK sulfonation degrees and DMF additions, the anti-microbial property of material is still very poor, illustrates the synthesis of SPEEK solution
It is critically important；Reference examples 9 and example 10 change MOF-SO3The usage amount of@MCM-22 compound particles, antibacterial effect are substantially reduced, said
Bright compound particle is excessively very few all to be produced a very large impact to the Bacteria suppression rate of material；Therefore had using chopsticks body of the present invention excellent
Different antibacterial effect.
