| Research Abstract |
We have prepared thermoreversible supramacromolecular ion gels via hydrogen bonding by blending a telechelic polymer and a multifunctional polymer (supramolecular cross-linker) in an ionic liquid. Supramacromolecular ion gels with best responsivity were obtained at a concentration with stoichiometric balance of hydrogen bonding functional units. The gel transition temperature increases with increase in the degree of hydrogen bonding groups per cross-linker, regardless of the same weight concentration of the cross-linker. Furthermore, bulk supramolecular polymer gels were prepared via hydrogen bonding.
