| Summary: | Cellulose aerogel (CA) has highly porous structure, environmentally friendly, thermally stable and flame retardant properties. These properties in material worlds have attracted large interest as a potentially industrial material. In this paper, cellulose aerogel with flame retardant was produced from pruned branches and bushes of blueberries wastes (PBBW). Firstly, cellulose raw material these wastes was obtained and then, cellulose aerogel via freeze-drying, followed by cellulose hydrogel production. Our reports showed that three dimensionally network aerogel structure prepared from NaOH/Urea as scaffold solution. The present cellulose aerogel has excellent flame retardancy, which can extinguish within 140 s. By the way, it was inferred thermal stability performance of cellulose aerogel could be efficient potential thermal insulating material. Besides, this process are sustainable, easily available at low cost and suitable for industrial applications.
