Cellulose nano fibers (CNF) are being considered as potential material for producing aerogel, an advanced materials for filtration technology. In this study, CNF were extracted from the sugarcance bagasse (a common agricultural waste) using ultrasonic technology and then fabricated with different additives including polyvinyl alcohol (PVA), polyethylene glycol (PEG) and graphene oxide (GO) to formulate aerogels.
