Developing biodegradable and biocompatible products to replace non-biodegradable petrochemical products is of great importance for supplementing rapidly diminishing oil resources and reducing environmental pollution. Based on this belief, the goal of this research was to introduce a green/clean procedure to prepare an aerogel using biodegradable cellulose as feedstock and renewable choline butyrate as solvent. Scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and thermogravimetric analysis (TGA) were used to investigate the morphology, chemical structure and thermostability. The results indicated that the cellulose aerogel possessed a porous structure which was composed of randomly oriented cellulose sheets. The cellulose aerogel had an amorphous structure compared to the original cellulose (cellulose I), and displayed good thermal stability.
