摘要：

In this study, cellulose possessing beta-cyclodextrin (beta-CD) is employed as a host molecule, and cellulose possessing ferrocene (Fe) is used as a guest polymer. The properties due to the host-guest interactions are presented. The results show that beta-CD-cellulose and Fc-cellulose can form inclusion complexes wherein hydrophobic interaction caused by beta-CD-cellulose and Fc-cellulose significantly affect the performance of the cellulose gel. A physical gel based on cellulose that can autonomously heal between cut surfaces after 24 h was formed under mild conditions. Moreover, ferrocene redox status affects the hydrophobic interaction, such that the hydrophobic interaction can strengthen the gel strength and affect the self-healing property.
