Cyclodextrin-based supramolecular hydrogel
WebJan 1, 2024 · In contrast by covalent crosslinking, cyclodextrin based hydrogels are constructed through dynamic noncovalent bonds, such as host–guest interactions and hydrogen bonds. Supramolecular crosslinking is a variety of physical interaction with great flexibility, and it can be easily to fabricate different kinds of “smart” hydrogels [ 23 ]. WebThe supramolecular hydrogel presented a porous network structure observed by positive fluorescence microscopy (PFM) was found to be thixotropic and reversibl. The gel kinetics has been studied by monitored the viscosity of the supramolecular system, which was well illustrated according to the Stokes-Einstein equation.
