摘要
以钛酸四丁酯为原料,纳米纤丝化纤维素(NFC)为模板,制备NFC/Ti O2气凝胶。采用扫描电子显微镜(SEM)、X射线衍射(XRD)、傅里叶变换红外光谱(FT-IR)、比表面积及孔径分析仪对其进行表征。结果表明:NFC/Ti O2气凝胶中NFC保留了其原有的空间网络结构;Ti O2主要以颗粒的形式附着在NFC表面;通过BET分析可知其比表面积为12.55 m2/g,平均孔径为17.07 nm。
Nanofibrillated cellulose（ NFC） / Ti O2 aerogel was prepared with tetrabutyl titanate as raw material and NFC as template. NFC / Ti O2 aerogel was characterized by scanning electron microscopy（ SEM）,X-ray diffraction（ XRD）,Fourier transform infrared（ FT-IR） and specific surface area and pore size analyzer,respectively. The results showed that the original space network structure of NFC was kept in NFC / Ti O2 aerogel. Ti O2 mainly existed in the form of particles attached on the surface of cellulose nanofibrils. For NFC / Ti O2 aerogel,the specific surface area was 12. 55 m2/ g and the average pore size was 17. 07 nm analyzed by BET method.
