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 being marked
Under quasi- test condition, embodiment 1 arrives embodiment 10, and staphylococcus aureus and Escherichia coli inhibiting rate are more than common antibacterial
Material changes the proportion of each raw material composition in anti-biotic material respectively, has different degrees of influence to the anti-microbial property of material,
Silica and MOF-SO3@MCM-22 nano material quality proportioning is 1:4, and when other ingredient dosages are fixed, antibacterial effect is most
It is good；It is worth noting that 11 modified Nano ZY-14CMS nano powder of embodiment, antibacterial effect and antibacterial stability are significantly mentioned
Height illustrates modified Nano ZY-14CMS nano powder to MOF-SO3The anti-microbial property of@MCM-22 tectum structure has preferably excellent
