Abstract:
A nanocellulose aerogel, a preparation method therefor and an application thereof. On the inside, the nanocellulose aerogel has a porous network structure, with an average pore diameter of 100-240nm and a porosity of 69-88%; the nanocellulose aerogel is prepared from nanocellulose, the nanocellulose has a length of 200-800nm and a diameter of 5-80nm, and the content of a surface carboxyl functional group is 0.3-1.0mmol/g. The nanocellulose aerogel has a high specific surface area and porosity, and can take into account both a resistance pressure drop and filtration efficiency; moreover, the nanocellulose itself likewise has a porous structure, which also has a certain interception effect on particulate matter.
