摘　　要：为了制备细菌纤维素超过滤、杀菌水吸附材料,探究过滤材料的性能,采用纯棉针织物作为过滤材料的基底,分别用Si O2,Al(OH)3,Ti O2进行改性处理,再运用细菌纤维素进行外层包覆,制备出纳米级的超过滤水吸附材料。详细阐述了细菌纤维素超过滤水吸附材料的制备过程,并结合电镜观察和红外分析,探究新型材料的元素组成、纳米结构特征及过滤、杀菌机理,通过对比过滤实验分析各阶段产物及涂覆循环数对材料过滤效果的影响,说明制备的细菌纤维素超过滤、杀菌水吸附材料具有优良的过滤性能,单次循环涂覆制备工艺已达到很好的过滤效果。In order to prepare bacterial cellulose ultrafiltration and sterilization water adsorbent material, the properties of the filter material were investigated. Cotton knitted fabric was used as the base of the filter material, with silica, aluminum hydroxide, and titanium dioxide modified treatment, respectively. And then bacterial cellulose was covered on above materials to obtain nano-grade ultra-absorbent material. Its filtration performance was also studied. In this paper, the preparation process of bacterial cellulose ultrafiltration water adsorbent material is described in detail. The elemental composition,nanostructure, filtration and sterilization mechanism are analyzed by electron microscopy and infrared spectroscopy. In addition, the effect of the product and the number of coating cycles on the filtration efficiency of the materials was also analyzed by comparing the filtration experiments. It showed that the prepared bactericidal cellulose had excellent filtration performance. The single cycle coating preparation process has achieved good filtration effect.
