Thermoreversible Gels from Mixtures of a High-melting Ionic Liquid and a Polar Polymer for Self-Healing Materials

Abstract

We investigate a new kind of PVOH physical gel in which the volatile water is replaced with a non-volatile ionic liquid (IL). High melting IL containing Br- anion was chosen so that the hydrogen-bond accepting Br- can enhance miscibility with PVOH while the high melting point can lead to solid mixtures at room temperature. The thermal and mechanical properties of the mixtures of IL and PVOH were investigated and the results are discussed in terms of the interaction between the two components. Thermal healing properties were evaluated visually by optical microscopy for macroscopic scratches after mild heating treatment.
