基于生物质模板制备ZIF-8及抗菌性能

Bio-template synthesis of ZIF-8 and its antibacterial property

摘要:

为赋予皮革表面优异的抗菌性,以己内酰胺改性酪素CA-CPL为模板原位生长金属有机骨架化合物ZIF-8,并将其应用于皮革涂饰中。结合XRD、SEM和TEM等结果发现：通过调整生物质模板的尺寸与形貌,成功生长出晶体结构完整的CA-CPL@ZIF-8。研究结果表明,随着CA-CPL@ZIF-8含量的增加,涂饰后皮革对大肠杆菌和金黄色葡萄球菌产生了明显的抗菌效果,当其含量为0.8%时,皮革对金黄色葡萄球菌的抑菌圈为4 mm。

Abstract:

In order to endow the leather with superior antibacterial behavior, metal-organic frameworks was synthesized by using CA-CPL as the template. Subsequently, CA-CPL@ZIF-8 was applied to leather finishing. The results of XRD, SEM and TEM showed that the CA-CPL@ZIF-8 with complete crystal structure was successfully grown by turning the size of the template. The results illustrated that antibacterial effect on E. coli and S. aureus of leather increased with the increase of CA-CPL@ZIF-8 content (when the dosage was 0.8%, the inhibition zone of S. aureus was 4 mm).
