Revealing the influences of cellulose on cellulose/SrF2 nanocomposites synthesized by microwave-assisted method

摘要

The purpose of this article was to investigate the effect of the cellulose content on the synthesis of cellulose/SrF2 nanocomposites, which were successfully synthesized by the microwave-assisted method at 100 degrees C for 20 min. These nanocomposites were investigated by X-ray powder diffraction (XRD), scanning electron microscopy (SEM), field emission scanning electron microscopy (FE-SEM), thermogravimetric analysis (TG), and derivative thermogravimetric (DTG). In addition to this, this synthetic route was also extended to fabricate the other cellulose/alkaline earth metal fluorides (MF2, M = Ca, Mg, Ba) nanocomposites. What's more, the influence of cellulose/alkaline earth metal fluorides (MF2, M = Ca, Mg, Sr, Ba) nanocomposites on the tensile properties of paper were also explored. The cellulose content is found to have a certain influence on the morphology, crystal lattice, crystallinity and thermostability of alkaline earth metal fluorides. The different types of alkaline earth metal fluorides have an effect on the tensile strength of paper. (C) 2016 Elsevier B.V. All rights reserved.
