| titleOfInvention | Preparation method of aerogel |
| abstract | The invention discloses a preparation method of beta-cyclodextrin polymer aerogel, which comprises the following steps: and sequentially adding the beta-cyclodextrin, the polyethylene glycol and the epichlorohydrin which are recrystallized twice into a sodium hydroxide solution, stirring and reacting until hydrogel is formed, then refrigerating and soaking the hydrogel, and finally freezing and freeze-drying to obtain the aerogel. The preparation method has the characteristics of flexible and simple process, low cost and short gelation time, adopts polyethylene glycol as a soft-segment polymer, further regulates and controls the properties of the beta-cyclodextrin polymer aerogel, and the apparent density of the prepared aerogel is 0.1-0.7 g/cm 3 Controllable, and has stable gel skeleton structure. The aerogel prepared by the invention has the basic characteristics of high porosity, large specific surface area, integral three-dimensional network structure and the like, maintains the capabilities of catalysis, identification, inclusion and slow release of cyclodextrin, and has specific adsorption capacity on aromatic organic matters such as toluene, aniline and the like. |
