摘要

对废纸纤维素进行处理，以甲基三甲氧基硅烷（MTMS）作为硅源，制备纤维素/SiO

复合水凝胶，经过冷冻干燥得到性能良好的纤维素/SiO

复合气凝胶。利用扫描电镜（SEM）、接触角测量仪及热重分析（TGA）等对制得的气凝胶进行了表征测试。结果显示材料由大孔、介孔、微孔组成，最低密度为0.107 g/cm

，具有较好的疏水性能，静态疏水接触角可达148.5°，力学性能良好，可实现50%范围内压缩后100%恢复，材料具备良好的吸附性能，吸附油污可达到本身质量的12.7倍，热稳定性提高。在处理有机废水，尤其是水体油污方面有着广阔的应用前景。

Abstract

The waste paper cellulose was treated

and the cellulose/SiO

composite hydrogel was prepared by using methyltrimethoxysilane (MTMS) as a silicon source

and freeze-dried to obtain a cellulose/SiO

composite aerogel having good performance. The prepared aerogels were characterized by scanning electron microscopy (SEM)

contact angle measuring instrument and thermogravimetric analysis (TGA). The

results show that the material consists of macropores

mesopores

and micropores with a minimum density of 0.107 g/cm

which has good hydrophobic properties

static hydrophobic contact angle of up to 148.5°

good mechanical properties

and 100% recovery after compression in 50% range. The material has good adsorption performance

and the adsorbed oil can reach 12.7 times of its own quality

and the thermal stability is improved. It has broad application prospects in the treatment of organic wastewater

especially water pollution.
