摘要:

为扩大纤维素膜的使用范围,使其可应用于医用、建筑等领域,利用纳米氧化锌具有紫外线屏蔽、抗菌等特性,采用原子层沉积(ALD)技术在纤维素膜表面沉积纳米氧化锌,制备具有紫外线阻隔以及抗菌功能的纤维素膜,并探讨不同ALD温度和循环次数对纤维素膜性能的影响。借助紫外分光光度计、扫描电子显微镜、X射线衍射仪、热重分析仪等对纤维素膜的结构和性能进行分析。结果表明:随着ALD温度和循环次数的增加,纤维素膜的紫外线透过率由74.50%下降至1.46%; ALD功能化纤维素膜对金黄色葡萄球菌的抑菌率高达99.9%;经改性的纤维素膜表面附着了六方晶系纤锌矿结构的纳米氧化锌层,残碳率由16.61%增加至31.20%。

Abstract:

In order to expand the use of cellulose membranes into medical, construction and other fields, with the characteristics of ultraviolet shielding, antibacterial of nano-zinc oxide, atomic layer depos-ition technology (ALD) were used to deposit nano-zinc oxide on the surface of cellulose membrane. The cellulose membrane was prepared to offer UV-blocking and antibacterial functions, and the effects of different temperatures and cycle numbers on the membrane properties were discussed. The structure and performance of the cellulose membranes treated with ALD were analyzed using ultraviolet spectrophotometer, scanning electron microscopy, X-ray diffraction, thermogravimetric analysis and other analytical tools. The results show that as the temperature and the number of cycles increase, the UV transmittance of the cellulose membrane treated with ALD is reduced from 74.50% to 1.46%, and the antibacterial rate of ALD functionalized cellulose membrane against Staphylococcus aureus reaches 99.9%. In addition, on the surface of the treated cellulose membrane with nano-zinc oxide with hexagonal wurtzite structure, the residual carbon rate increases from 16.61% to 31.20%.

Key words: cellulose membrane, atomic layer deposition technology, nano-zinc oxide, UV-blocking, antibacterial property
