Self-Healable Poly(ionic liquid) Copolymers Driven by Polar and Dipolar Forces.

ABSTRACT: Commodity aliphatic and aromatic acrylic-based copolymers self-heal due to ubiquitous key-and-lock, ring-and-lock, and fluorophilic-σ-lock van der Waals (vdW) interactions. However, the role of these interactions in the presence of covalently copolymerized ionic liquid (IL) is not known. This study is driven by the hypothesis that covalently incorporated cation-anion pairs to form poly(ionic liquid) copolymers (PILCs) can perturb inter- or intra-chain vdW interactions reflected in mechanical and electrical responses. To test this hypothesis, we synthesized a series of PILCs comprising of pentafluorostyrene (PFS) and imidazolium-based IL monomers with variable-length aliphatic tails (methyl and butyl).
