The invention proposes a preparation method of an environment-responsive cellulose aerogel. The key point of the preparation method is to use an environment-responsive polymer monomer and reactive organosiloxane to copolymerize to form a block copolymer, which is used as a fiber cellulose nanowires (CNFs); the chemically cross-linked CNFs are freeze-dried and thermally cross-linked to form cellulose aerogels with excellent mechanical properties and environmental responsiveness. The aerogel material combines high specific surface area, biocompatibility, regular microstructure and environmental responsiveness (such as temperature, carbon dioxide, pH), and the aerogel structure has excellent stability, which can be used in protein adsorption and desorption. , dye adsorption, directional transport and other fields have broad application prospects. |
