Synthesis, properties, and function of self-healing polymer-based on eugenol

Eugenol-based self-healing polymers were synthesized in a very short time of 94–159 s. Polymerization of eugenol catalyzed by H2SO4-CH3COOH yielded the corresponding self-healing polymers in quantitative yields in the range of molecular weight (5.18–15.10) × 105 g/mol. The polymer exhibited self-healing behavior at room temperature due to hydrogen bonds between the hydroxyl groups of polyeugenol and the hydroxyl groups of sulfuric acid. This material can function as a polyelectrolyte and a novel self-healing catalyst for biodiesel production.
