  • Polysaccharide aerogel
    Patent number: 11103845
    Abstract: Disclosed herein is a polysaccharide aerogel comprising cotton cellulose fibres and a method of preparing the polysaccharide aerogel. The method comprises: mixing cotton cellulose fibres and a cross-linker to form a mixture; sonicating the mixture; freezing the sonicated mixture; and freeze drying the frozen mixture to form an aerogel. A further embodiment provides a polysaccharide aerogel comprising cotton cellulose fibres and paper cellulose fibres in a weight ratio of 1:1 to 1:6 and a method of preparation thereof wherein in the mixing step, the paper cellulose fibres are added to the cotton cellulose fibres to form a mixture.
    Type: Grant
