纳米纤维素基高吸水抗菌抗氧化双相凝胶的制备与性能
Preparation and Properties of Nanocellulose-based Superabsorbent Antibacterial and Antioxidant Biphasic Gels
摘要
Abstract
The aerogel-hydrogel biphasic gels with high water absorption,antibacterial and antioxidant properties were prepared by using nanocellulose fibers as the hydrogel skeleton.The structure and properties of the aerogel-hydrogel biphasic gels were characterized by scanning electron microscopy,Fourier transform infrared spectroscopy,ultraviolet-visible spectrophotometer.The analysis results showed that the aerogel phase had excel-lent water absorption properties and the water absorption rate reached 1342.2%within 5 hours.After the aerogel phase absorbed water to form the hydrogel phase,tannic acid was released,the inhibition effect on Staphylococ-cus aureus reached 98.72%and that on Escherichia coli reached 83.62%,demonstrating excellent antibacterial properties.The removal efficiency of free radical was 91.89%,which could effectively inhibit the generation of reactive oxygen species and reduce the occurrence of inflammation,showing application potential in wound care.关键词
