毛竹纳米纤丝化纤维素/TiO2气凝胶的制备及表征

Abstract

Abstract: Nanofibrillated cellulose(NFC)/TiO₂ aerogel was prepared with tetrabutyl titanate as raw material and NFC as template. NFC/TiO₂ 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/TiO₂ aerogel.TiO₂ mainly existed in the form of particles attached on the surface of cellulose nanofibrils.For NFC/TiO₂ aerogel, the specific surface area was 12.55 m²/g and the average pore size was 17.07 nm analyzed by BET method.

Key words: Phyllostachys heterocycla cv. Pubescens, nanofibrillated cellulose, template, titanium dioxide

CLC Number:

TQ352
O636
