Characteristics：
1. The gel combined with cyclodextrin can include various guest molecules, broadening the application range of the gel.
2. After being made, it is thermally reversible, and becomes a fluid liquid at 50°C, and then solidifies into a gel again when it is lowered to room temperature.
3. The flexibility and mechanical strength of the gel can be adjusted.
4. The stability of cyclodextrin gel is better.
