Multi-functional supramolecular materials by mixing hydrophobic cyclodextrin based host polymer and guest polymer;; recycle, healing, and toughening

摘要

We successfully prepared multi-functional cyclodextrin (CD) based supramolecular elastomers. Until now, elastomers with CDs have been obtained by forming rotaxane structure 1 or polymerizing complexes between CD monomers and guest monomers 2 . Mixing host polymer and guest polymer has not been tried yet to prepare elastomers. We prepared elastomers from host polymer and guest polymer by mechanial mix. Mechanically mixed elastomers were not only tough, but also recyclable and healable.
