Cellulose aerogels is considered as one of the most promising eco-friendly heat insulating materials due to its abundant internal pores, low density, low thermal conductivity and high mechanical strength. However, cellulose aerogel is easy to ignite, which makes it impossible to be used as building materials or domestic appliances. In this regards, in this research first nanocellulose aerogel prepared from waste newspaper and then for the flame retardant modification to it, cellulose -magnesium hydroxide nanocomposite aerogels synthesized. This environmentally friendly method for the preparation of flame retardant nanocomposites not only reduces the waste newspaper pollution but also promotes the application of cellulose aerogels in heat insulating materials. For the studied samples some characterizations such as X-ray diffraction, Surface morphology, density and porosity calculation and the flame retardant properties were carried out.
